Diadrake

Diadrake, known (roughly) as "Admarat" (アドマレイト) in Japan, is an enemy Mechaniloid fought in Mega Man ZX. It appears as one of the sub-bosses of Area I, a confinement center where Hurricaune the Wolveroid terrifies the captives. Diadrake originally belonged to a wealthy individual, but was infected with a virus several days after purchase, which made it act strangely. It was disposed of soon after. It is equipped with a dispersion laser in its mouth.

Etymology
Its name is probably a combination of adamant (アダマインタイン, which is also known as adamantine and other names) and drake (ドレイク, an archaic word for dragon).
