I've seen a ton of Batman gauntlets (insider suit, bloodlusted, etc) but none fall under standard conditions. So, enjoy.
Rules (these are important... don't skim over them):
-Always a random encounter (that means no prep, people).
-Always begin 50 feet apart on opposite sides, visible but near cover.
-Batman has 7 hours rest between matches. During rest, he has access to:
A) Alfred is waiting in a room with all of the medical supplies from the batcave.
B) An ammunition room with all of his standard weapons... smoke pellets, small explosives, grappling lines, assorted batarangs. Basic stuff, nothing over-the-top like freeze tech or the brain fart card of doom, silly. Supplies to repair his cowl / armor as well.
C) And how could rest be complete without a cozy bed as well?
-Everyone (Batman and his gauntlet foes) are in character, but all are determined to win.
-Batman knows he's going into a series of fights.
-Standard elimination rules apply.
-All gauntlet characters have standard gear.
-All DC characters are pre-New 52
-Batman has no knowledge of the Marvel characters and vice versa.
