Babies slowly float towards Isaac, occasionally shooting a single blood shot. They also have the ability to teleport to anywhere in the room, occasionally close to Isaac. They usually teleport after a shot, the only random element is the shooting, and they have no specific cue to indicate incoming attacks.
They have much higher health and are more aggressive than the regular Baby.
Instead of the normal one shot, the Angel Baby fires 3 blood shots at Isaac. When fighting against Isaac, they will shoot regular tears. They also teleport more often, usually near Isaac.
- Angel Babies will sometimes shoot slowing tears. (needs confirmation)
- Version 1.33 introduced a bug called "Psy Baby" which was fixed in 1.4
- Babies always spawn in pairs or fours. The lowest spawning babies in each room were always the psychic ones, whether normal or angel. This also applied to Isaac and ??? spawning 2 angel babies; each time they were spawned, the lower one of the two would be psychic.
- Babies use the same death sounds as gooballs from the game World of Goo.
