Batman Birth of the Demon:
After taking out all the men but one on the digging site, Batman mistakenly lets his guard down around one who succeeds in knocking him down into toxic waste grounds.
As a result of being exposed to the toxic waste, Bruce has become noticeably ill with a serious high fever as we see Alfred, Talia, and Ra's point out how sick he appears.
Despite his illness, Bruce goes on to fight Ra's Al Ghul (who hasn't had a dip in the lazarus pit so he wasn't in his typical prime form either) in a brutal battle where they're both severally burned as they fight in fire for a short period of time with neither showing no signs of pain and Bruce managing to get the upperhand. We then see Bruce manage to yet again get the upperhand as he successfully fends off Ra's attack despite being blinded by the wind of sand. With Bruce still blinded however, Ra's takes advantage of the opening taking Bruce down with the shovel nearby then impaling the shovel seemingly to his heart. However, through an inhuman act of stamina and willpower, Bruce still rises and wrestles Ra's into the lazarus pit close by ending their battle in a stalemate. We then see Bruce is completely healed as a result of being inside the lazarus pit as he rises out of the sand that he's buried in.
Withstands a ton of punishment from The Sensei (who's had centuries to perfect his martial arts skill) with his arm and fingers getting broken, being blinded, even impaled and yet he's still able to impressively fight on and outsmart The Sensei to win the fight. Which proved The Sensei wrong about it only taking 1 minute to break him (Batman #671)
