Chase #8

After she tries unsuccesfully to hack Oracle's files in order to find information about Bats, he is warned by Oracle herself, but he answers that he already knows who is trying to expose him and that he is already working on it as he demonstrates this first by hacking into DEO's systems, then by spying on Chase talking to her superiors despite her line is protected also by a white noiser that should prevent anyone from listening in.
Later, the Dark Knight invites her to a party he'll attend in his Bruce Wayne persona and totally fools her by acting like a rich snob, leading her to think that it's Alan Scott (i.e. the first Green Lantern) who is Batman
Finally, he arranges things for her to realize she doesn't really want to unmask Batman (something he already knew), in the process proving unnecessary Nightwing's precaution of having a disguised as Bats Alan switch with the Dark Knight
Knightquest: the Search
1 - While having his back broken & confined to a wheelchair as Bruce Wayne, he uses his contacts with a Mister Jones (J'onn?) at the Justice League's headquarters to assemble a team consisting of Bronze Tiger, Gipsy and Green Arrow (Oliver Queen) to save Jack Drake (Robin III's father) and Dr Shondra Kingsolving from their kidnappers. Notice how Batman shows his smarts by forseeing the assassination attempt against him and Bronze Tiger's save, arranging for a transmitter planted on one of the killers to lead his team to the killers'hideout, and figuring out the presence of Gipsy in the hotel room. (JLA Task Force #5)
2- Forsees the second assasination on him, escapes it, and reveals that he was disguising as.....himself the whole time in order to make Bronze Tiger and co, who would have suspected of someone like Bruce Wayne organizing this rescue mission, that they were just dealing with someone pretending to be Wayne, thus protecting his secret identity (JLA Task Force #6)
just to show that Batman's ruse succeeded:
3 - Reveals that he had 4 ways prepared to leave Santa Prisca (i.e. where the action was taking place) in case of need (JLA: Task Force #6)

The Dark Knight has to face his old foe, Doctor Phosphorus. Just to point out how much formidable Phosphorus is:
In their first round, Batman uses a clever battle tactic, but doesn't manage to beat his enemy due to the fact that the latter has grown stronger since their last clash, as mentioned by Bats himself
Apparently, Phosphorus has turned into living fire
How to beat him? Well, thanks to an hint casually given him by Alfred, the Caped Cruiser decides to use baking soda to neutralize the villain's power, and, after successfully executing this plan, owns him with a punch

then, assisted by a disguised as the President Alfred, luring KGBeast's spy into the open and the Beast himself into a trap that will ultimately cost his defeat (see later in the issue):
Detective Comics #468
A group of JLAers formed by Atom, Batman, Black Canary, Elongated Man, Green Arrow and Hawkman has to face the Calculator (i.e. the same super-villain who will later appear in Identity Crisis), who has already given a tough fight to any of them thanks to his ability to produce out of thin air counters to their abilities & gadgets. Each time he was defeated, he managed to press a special button , just before being taken out. Because of this, he is not only able to prove to the Leaguers that he can't anymore be beaten by any of them, but also shows them, by taking all of them out when they launch a combined attack, that he is too much for them even if they team-work.
Nonetheless, Bats later manages to defeat Calculator on his own thanks to a brilliant plan that showcases his great forward thinking and is implemented perfectly by the Dark Knight, turning his opponent's own ability against him
Blue Beetle #18 & 25
Correctly mistrusting the Reach (race of aliens whose goal is to covertly conquering Earth while pretending to be friendly), Bats arranges for a satellite with a payload to be used against them, and for the Teen Titans to protect said satellite. The young heroes, helped by the new Blue Beetle, succeed in protecting it.
Later, the satellite turns out to be instrumental in ruining Reach's scheme, transmitting their plan of world domination all over the world thanks to Beetle cooperating with Batman and Oracle to make this happen.
After studying Know Man's technology (given to him by a Controller) in seemingly a few minutes, he quickly comes up with a plan for Martian Manhunter, Dr. Destiny, and Aquaman to free the minds of everyone on earth and restore reality itself using their telepathy in combination with the technology (Justice League: A Midsummer's Nightmare #3)
Studying the Starro bot made of alien technology, he learns how it works and thinks up a plan for the JLA to counter them (JLA #23)
Predicting the ill effects a psychological attack could have on him, The Dark Knight has prepared a back-up identity in order to be able to function despite the attack, a move that proves itself useful once Simon Hurt turns off the "mainstream" Batman's identity (as shown in the "Batman: RIP" story arc) (Batman #679)
Batman #680 & 681 (end of Batman: RIP)
The Black Glove (a "club" that has been planning the Dark Knight's demise for years) finds out at its expenses how much ready is Batman for everything. First, Joker's new, lethal Venom doesn't find Bats unprepared, KOing him instead of flat out killing him:
And it's revealed that an earlier attempt to kill the Caped Crusader by poisoning him was totally unsuccessful
Then, as the Joker predicts, not only the Dark Knight is able to escape from his grave (literally) with his faculties intact, but the Black Glove ends up losing control of Arkham Asylum (that they previously conquered), all the doors closing before them
Finally, Batman reveals he has (rightly) suspected of Jezebel Jet's involvement in the Black Glove for a long time, thus only pretending to love her while finding out everything about her and deprieving her of the only thing she really cared about
Activates his JLA emergency protocol having replicated Mr. Terrific's t-sphere technology and forming a new JLA to replace the previous one just in case they should go MIA (JLA #69 - begin of the Obsidian Age saga)
JLA #74-75 (end of the Obsidian Age saga)
While being 15000 years in the past fighting alongside the Justice League and being on the losing end against the League of Ancients, who are being manipulated by one of their own (aka atlantean sorceress Gaemnae, who wants to eliminate both leagues in order to insure that Atlantis rules above all and is determined to kill her own team-mates after the fight with the JLA weakens them), Batman takes out Sela & saves Wonder Woman, then shares with her & makes her accept the plan Manitou Raven (the only one of the Ancients who understood they're being manipulated) formulated and Bats deems as the only way to save themselves & have a chance to continue the fight. Said plan being to use GL Kyle's heart (who valiantly sacrifies himself after Raven spoke to him) to save the spirits of the Leaguers
Then, Bats begins to plan things out: first, he and the Leaguers convince Raven to avoid a direct battle against Gaemnae (a fight he could have lose), opting instead to cast a spell of containment (which will be broken only by his future self) on her (and themselves) and strategize.
Then, he anticipates to Raven that, in order to fix things, the present day JLA (i.e. the one that formed during the main rooster's absence as devised by the Dark Knight himself) has to travel in the past, confront Gaemnae there and eliminate her source of power, things that the JLA indeed decides to do upon consulting with present day Raven (i.e. the same one who saved the League's spirits, but after he & said spirits remained confined for 15000 years until a time-travelling from the past Raven broke the containment spell (freeing also Gaemnae in the process)).
Later, while in the present and in sort of zombie form, and knowing that Jason Blood is inside Gaemnae, exploites this to his advantage by leading J'onn to have Blood change to his alter-ego, aka Etrigan the Demon, and J'onn later complies
Then (i.e. just after the Gaemnae is tricked to ressurrect the main rooster of the League to their real bodies), therefore, Etrigan bursts out of the atlantean witch and starts kicking her butt (thus temporarly turning the fight in the JLA's favour), before threatening to turn rougue and having to be put on its place by Batman's contingence against him (see JLA #69), aka Faith, and blasting alongside her at Gaemnae some more
JLA #86-89
Martian Manhunter, upon overcoming his weakness to fire, got possessed by the spirit of, and reverted to, a Burning Martian, i.e. the way martians were before the Guardians of the Universe tampered with their genetics and made the fearful of fire (i.e. what, along suffering, enables the burning martians to breed) in order to spare the universe from the threat they could have become. J'onn, now calling himself Fernus the Burning, handled Supes and Firestorm and is now attacking his other team-mates. The JLA manages to survive this first clash, and decides that the best way to handle J'onn is to travel to the Phantom Zone and get one White martian in order to get inside knowledge about their fellow martian. Bats, however, states he has already a contingency in place in case their trip to the Phantom Zone goes bad
It turns out, Batman's contingency will be needed, since Fernus anticipated the League's tactics, travelled to the Phantom Zone himself and killed the White martians (he is literally the Burning, and the white martians were still weak to fire), and is now manhandling the JLA. Only the Dark Knight is able to escape in order to implement his back-up plan
as later noted by the Leaguers once John Stewart has saved them and told them about Fernus' history
Batman's plan? To get the only one who, in his opinion, can stop the Burning martian: Plastic Man. Unfortunately, Plas has self-hypnotized in order to forget his super-hero life and stay with his son, and it takes the latter, once Bats explains just how badly his father is needed, to get Plastic Man back in the game
So, Plas intervenes, and does so just in time, since Fernus has arranged nukes to be launched on various cities (while distracting the Leaguers by targetting their loved ones), has handled the JLA while they were trying to dispose of the nukes, and has taken out Bats, who is saved from a fall to death by Plastic Man himself.
Then, Plas attacks Fernus & frees the JLAers, and proves that Batman was right in believing the elastic hero to be the key to beat the Burning. In fact, as forseen by the Dark Knight, Fernus can't take control of Plastic Man's mind, and Plas is superior to the martian as far as shape-shifting is concerned. Thus, PM is able to stall Fernus long enough for the Leaguers to handle the nukes (the last one (kept hidden by the Burning), hits its target despite Superman's effort, but that city gets evacuated by Flash so no life gets lost) and land an attack on the Burning
NOTE: Fernus is later defeated, with an assist from the JLA, by Martian Manhunter himself, who was able to literally burst free from Fernus mainly thanks to Atom, Major Disaster, Manitou Raven and the sacrifice of J'onn's lover Scorch
JLA #112-114
The League has to face the Crime Syndacate of America and a mega-powerful weapon from Qward that can blow up planets and stars. So, also the reserves are called in by the Martian Manhunter. Bats "suggests" him to send 3 teams to deal with the problems instead of 2, the third being headed for the Syndacate's world (aka Earth Two) in the anti-matter universe to gather intelligence and to find something to use against the CSA to beat them or force them back. Then he switches sides with J'onn and disguises as him while a morphed like Batman MM goes with the team bound for Earth 2, in order to have a telephat beyond enemy lines without their knowledge
This tactic will later pay his fruits, since not only J'onn & co will find info that will lead to the CSA being in debt with the JLA, but will also destabilize things on the Syndacate's Earth so much that Ultraman & co will at least be too busy to do anything but take care of their planet, both things meaning the Crime Syndacate won't be a threat to the League and the positive matter universe for awhile
Against the Qwardian uber-weapon, instead, Bats finds a simple but effective way to overcome the fact that it has already battled both the JLA & the CSA & developed counters against them, and to take it by surprise long enough to disable its guns and break into it: having Supes bring spare uniforms so that the Leaguers and the CSAers (save for Bats & Owlman) can disguise as each others (still, it's to Flash and the Construct whom the League and the Syndacate owe the final victory).
Trinity #5 (2008)
With Superman's help, Batman comes up with a way to stop Konvikt (alien monster able to own the JLA and one-punch KO Kal), namely a weapon designed to put the monster to sleep through a special gas. Said gas works, as the monster finds out when Wonder Woman prevents him from holding his breath.
Defeats 3 White Martians by luring them into a trap exposing their weakness to fire (JLA #3-4)
JLA #56 (Batman's actions) and JLA #57 & #58 (details of Batman's actions and its consequences) - part of the "Terror Incognita" story arc
After finding out the White Martians' hideout, Batman successfully sneakes into it by using Brain-Wave's neural amplifier (taken from the JLA's trophy room before teleporting out of the Watchtower). He remains there undetected while gathering info on the WM's plans (using a martian-to-english translator in the process) until the martians learn of his presence due to J'onn unwittingly betraying it. Then, Bats fights off various attacking White Martians (who got detected due to the neural amplifier) with a flame-thrower. Despite, in the end, he gets subdued and Martian Manhunter has to save him, the Dark Knight still manages to reach his goal, i.e. to bring Atom near J'onn. Atom later is instrumental in disposing of the psi-spikes in the green martian's brain (put there by the WM) & healing J'onn enough for him to telephatically shield his mind, in freeing the JLA from the Phantom Zone, and in implementing Martian Manhunter's plan
The Key, in order to avoid capture and exile in another planet at the hands of a Squad led by Amanda Waller, leads some of his fellow supervillains to surrender to the Justice League, convinced he would be able to free himself and the rest once the JLA solve their problem for them. Too bad Bats has studied him, so Key finds himself in a prison he is unable to escape from (at least for now) (Justice League Of America #18 (2008))
Justice League v1 #112
In the previous issue, the League faced (and beated) the very first version of the Injustice Gang led by the mysterious Libra, who caused the Leaguers to lose half their powers & skills in order to test a machine that was designed to make him one with the galaxy (and which ultimately caused his death). So, in order to recover the lost abilities, Atom has suggested to use Amazo to get them back, and then arrange him to be de-activated and put in a device in order to synphon off back to the JLAers the missing power & skills. While the rest of his team set in motion to enact Atom's plan, a Batman who has only half his intellect still manages to find out the flaw in the League's strategy (namely that Amazo would guess their plan due to having half Batman's detective skills & would therefore take advantage of that to take the team out) and to arrange things for them & him to get their abilities back and for the android to be defeated.
NOTE: The comic from where the above scans were taken is a pre-crisis one but, since nothing suggests its story got ret-connetted out post crisis, and given that the fact we saw in Identity Crisis #3 (aka a post crisis comic) the Injustice Gang (aka the same team the JLA faced in Justice League of America v1 #111, i.e. the issue that shows what caused what happened in the comic we are talking about)'s satellite suggests the events shown above could have happened, we saw fit to include the above feat
Amazons Attack #5
A magical force-field has cut off Washington from the rest of the state, leaving inside Batman and the attacking amazons while preventing the other heroes (including big guns like Superman, Zatanna and Martian Manhunters). After having deduced it was Circe's doing, Bats confronts her, electrocuting one of her followers into unconsciousness while reciting words given him by Zatanna that nullify Circe's magic for an hour, then knocks the witch out. Thus, the magical shield disappears and the big guns enter, turning the tide of the battle.
Batman And The Outsiders #3 (2008)
In the previous issue, the new version of the Outsiders (whose leader is Batman) captured an OMAC. Bats anticipates the arrival of part of the League to retrieve the OMAC, and the "awakening" of the latter to cause trouble, and is ready to manipulate things & lead Metamorpho & co to solve both problems. So, the OMAC unit is stopped by the Outsiders (wheras the Leaguers failed), the JLA is left with a dead shell, Geoforce is fine with being transferred from the League to Dark Knight's new team, and an OMAC remains to Batman & co for further study.
After Tangent Batman helps him escape and bring him to the other Tangent heroes (the Outsiders), Bats plans the liberation of his JLA team-mates and of Tangent Atom, a goal he and the Outsiders reach, discovering in the process that the Superman travelled to the League's Earth to conquer it (Tangent: Superman's Reign #7)
Thus, the Dark Knight take steps to take the Superman out. First he leads the assembled JLAers and Outsiders to break into Superman's private computer room, in order to learn the wherabouts of Lori Lemaris (i.e. the Superman (aka Harvey Dent)'s wife), an information he didn't get in his previous trip to the Core. Then he confronts Lori in her home and convinces her to help taking down his former husband (Tangent: Superman's Reign #9-10)
Once back on his Earth, Bats divides the JLA, the Outsiders and an assemblage of supervillains (who first worked for the Superman but then were persuaded to switch sides) in 4 teams: 2 of them to attack Superman directly, in order to determine his strenght & weaknesses and have him waste energies. A third to confront Dent's allies and take out Tangent Ultrahumanite (Harvey's former archfoe who could threaten the planet and was reprogrammed to serve his former enemy), a goal they nearly reach (he is finished by the Man Of Steel), but at the apparent cost of Tangent Batman's life. Finally, Batman leads the fourth team in the final showdown against the Superman & co, defeating them (ironically with another Superman delivering the final blow). Thus, the defeated enemies are imprisoned and transferred elsewhere (Tangent: Superman's Reign #12).
JLA Classified #36
Darrin Profitt is a regular guy who stumbled upon Doctor Destiny (aka John Dee)'s Materioptikon and used it to create various realities and versions of himself in order to try his luck and become a successful man (discharging the realities where he failed in the process). Accomplished that, he used the same system to find a way to beat the League and rule the world, and in the 3 remaining scenarios he became the ultra-powerful Red King. In one of these 3 realities, he managed to manipulate events in order to be accepted with open arms in the Justice League (see JLA Classified #33). Unfortunately for him, Batman has figured out he isn't what he seems and, after talking with Destiny, the Dark Knight and Dee come up with a plan to take Profitt (both the one in mainstream Earth and the Red King survivor of a reality he had to erase where he won but the world was ravaged and the few people who remained hated him) out, a plan the League successfully enact (thanks in no small part to the third reality's only other survivor, aka Plastic Man).
Outsmarts the Shaggy Man by luring him into a trap
Detective Comics #840
A Ra's Al Ghul fresh from ressurection has come to Gotham in order to set up there his base of operation and kill the "Detective" (i.e. Batman). This obviously doesn't sit well with the Dark Knight, especially considering the fact his opponent knows his secret identity. So, Bats plans the defeat of his long time enemy, finds his temporary head-quarters, and disable all his henchmen in order to confront him one to one and subdue him
Then, he brings a drugged Ra's in Arkham's Asylum under a false identity, making sure he is kept in isolation and constantly under medication that keeps him nearly unable to move or to speak, ending his threat for the forseeable future.
After beating an army of Lex's robo-soldiers last issue, Batman uses one of them he re-programmed to sneak in the base "Luthor" was in, while causing a temporary black-out. Later he has that same robot save him from one of his fellows and cause the self-destruction of all the others, thus ruining Luthor's plan to seize control of the USA (albeit the Lex Luthor in the military base is revealed to be a mind-controlled robotic sosia, thus allowing the real Lex to escape justice) (Batman Confidential #6)

Trying to find out how to take out Superman, Bats figures out what red sun radiation truly does to him and designs a projector of said energy, as noted by Supes himself (Superman #667)
Having to face a Supes gone rougue, Bats uses a kryptonite sample he had in his belt to incapacitate him, long enough for the Dark Knight to merge with the Black Rock, a move that saves his life and makes him able to slug it out with the Man of Steel, but unfortunately also causes him to be possessed and to battle Kal El after the kryptonian (thanks in no small part to Lois) freed himself from alien control (Superman/Batman #32)
After being entrusted with (supposedly) the last piece of kryptonite on earth by Superman, it turns out that he now has much more kryptonite then anyone else known on earth at the moment including other unique types of kryptonite within the most secure part of his batcave (Superman Batman #49).
Cosmic Odyssey
A group of heroes including Batman is summoned to New Genesis by Highfather and Darkseid, the latter revealing that 4 aspects of the Anti-life entity are loose on this universe and, if they manage to destroy 4 key solar systems of the Milky Way, the whole galaxy will collapse. This would cause the Anti life entity to enter wholly our universe, which would ultimately results in its and the universe's destruction. So, the heroes are enlisted to stop the aspects. However, Bats doesn't trust Darkseid and believes he has a secret agenda, so he phones a friend and ask him to keep an eye on the ruler of Apokolyps:
It turns out the Dark Knight was right, since Darkseid does have in mind to exploit the situation to his advantage by absorbing the Anti-life's power to become ruler of the universe, something that doesn't escape to Batman's friend
Said friend is revealed to be Doctor Fate, who is instrumental in saving reality from the Anti-life essence once Darkseid's plan backfires
After outsmarting/trapping Desaad, he takes his identity tricking Darkseid into thinking its really Desaad he's been speaking to for several months.
