Fantacle

Fantacle (ファンタクル) is a plant-like Mechaniloid enemy from Mega Man ZX Advent. At first they may look like simple flowers living on the walls of buildings, but when it detects an intruder, it spins its razor sharp flower. The flower itself is invincible, its weakness being the central part with a red core attached to the wall. They appear in the Tower of Verdure.
