Skull Fish

Skull Fish is one of the many Chaos creatures. They do not have a ranged attack nor a melee attack, so they rely on their speed to approach the player and explode nearby to cause damage. They can float, emit a distinct sound, possess a tail of reddish light which makes them easier to spot.

They appear in groups of either 2 or 3. They have little health, it's even possible to destroy one and its explosion cause a chain reaction on other Skull Fish. Skull Fish are notably the only members of Chaos who are not affected by buffs from the Slayer or the Hunter.

Skull Fish first appear in Research, although they don't become common until Genesis Part 1.
