Ultra Pride

Ultra Pride is a mini-boss and one of the Seven Super Deadly Sins. Ultra Pride resembles Edmund McMillen, while the Ultra Pride Baby resembles Florian Himsl.

Behavior
Ultra Pride differs from its normal counterparts by having attacks more similar to Super Sloth and a Baby than Pride. They perform attacks independently of each other.

Edmund wanders randomly around the room and performs one of two attacks: Utra Pride Edmund deals a whole heart of contact damage.
 * Shoots out 3 arcing homing projectiles.
 * Throws out a horizontal line of Green Creep if Isaac is to his left or right.
 * The line is cone-shaped and will always be wider to the right end, no matter which direction it was sent from.

Florian slowly floats towards Isaac and can randomly teleport around the room.
 * If Isaac is close, he periodically shoots out a homing projectile that deals one full heart of damage.
 * Florian has slightly more health than other Babies, 30 HP instead of 25.

If Florian is defeated first, Ultra Pride drops The Left Hand, regardless of whether or not it has already appeared during that run. If this is the first time it is defeated, the Left Hand achievement is also unlocked. If Edmund is defeated first, there is a 25% chance of a pedestal item from the treasure room appearing. Otherwise, the player receives a normal room clear drop. If Edmund is defeated first, Ultra Pride has a 25% chance to drop the if it has been unlocked.
