Raven bleeding as the result of Catwoman's SP1.
Bleeding is a type of Damage-Over-Time in the game.
Bleeding characters take 20% increased damage from all sources. This stacks additively with itself (e.g. if there are 3 active bleeds on a character, they take 60% increased damage; the most of this effect observed is at 5 bleeds, or +100% damage). Bleeding's damage boost serves as a damage multiplier, therefore, it will multiply the damage, including other sources of damage boosts or bonus damage from special attacks' mini-game performances, while those damage boosts stack additively with each other. With enough stacks of bleeding, attacks can deal damage to enemies who have over 100% damage reduction, which normally reduce all damage received to zero (damage reduction also acts as a damage multiplier, so at 100% its multiplier will be 0 and no damage will be taken regardless of how many damage boosts other than bleeding).
This works with almost any source of damage there is, even unconventional ones like the passives of Hal Jordan/Red Lantern (self-damage would be increased if he's bleeding), Black Adam/Prime and Black Adam/Regime's damage reflect, The Joker/Insurgency and The Joker/Prime's damage upon KO, or Batgirl/Cassandra Cain's tag in attack, or the unique damage effects of The Ibistick or the LexCorp Set.
They also allow any character that can normally only KO one opponent with a special to KO multiple opponents. However, a special may fail to KO if the bleed deals damage and makes enemy health reach to 1 before the hit lands. It is currently unknown if this was intentional or a bug.
