Isaz and Sowilo

Isaz and Sowilo (イーサ&ソウェル) is a two-headed sphinx-like tank from Mega Man Xtreme 2, the second boss of the final stages. It goes forward trying to hit the player with its drill, leaving only a hovering platform to stand in, but Zero can push it away with his Z-Saber. The upper head releases three spheres from its mouth in the players direction, and the lower head shoots a missile up that falls where the player was when released.

Trivia

 * Their names possibly comes from the letters Isaz and Sowilo from the runic alphabet.
 * It has Sigma's symbol on its side, and the faces are similar to Sigma's face.
 * Īsa (イーサ) can also be translated as "Ether", but it doesn't match with Sowilo.
