Retch

[Chemoeum]

Or maybe the Retch gives off some kind of status effect, kind of like the Bombshell with his health meter replaced with a shield when he retracts. He may poison them, wear their health away, and stay poisoned even when outside of its spores.

May have three health (because of its low range of two), or one or two health (if Retch is granted the ability to move after its spores are toggled, or if Retch can kill any enemy that survives the spores closest to him),or just one health (if Retch can attempt a secondary move up to three spaces of its spore range, a toxic shock that deals one damage and poisons the enemy).
