AIsaac


Spawns a free bimb every floor.
If you dont use your bimbs, he will place one automatically after some time. The more bimbs he has, the less is the cooldown.
Your bimbs have +25% explosion radius (huge).
The damage you take from your own bimbs counts as "self-damage", doesn’t decrease deal chance and drains the red health first.
Starts with all stats slightly lowered, and with a Bomb Bag. His main mechanic is "bimb strats".
He gets different buffs or effects based on how his bimbs (bombs) explode.[isaacguru.com]

RIsaac


Starts with Metal Plate
Follows your cursor and shoots towards it
Hold LMB to make him stop moving
Hold RMB to make him stop shooting

LAIsaac and RAIsaac


2 characters at once
LAI doesnt shoot and cant place bimbs
RAI is controlled by arrow keys and is invulnerable to any damage
