Sasoreenu

Sasoreenu (サソリーヌ) is a scorpion robot enemy from Mega Man 4 and Mega Man IV that only appears in Pharaoh Man's stage, on the sand area in the surface. They are invincible as they emerge from or sink back into the sand, and while on the surface they tend to zoom forward to try to sting Mega Man.
