Bonsect

Bonsect (ボンセクト) is a caterpillar-like enemy from Mega Man Zero 4. It comes in different lengths and appears out of enclaves in the walls or simply out of thin air, and will slowly home in on Zero. It appears in Noble Mandrago's stage, Popla Cocapetri's stage, as well as during the final battle with Dr. Weil, the latter summoning them via green portals.
