Morph Moth (Metamor Mothmeanos in Japan) is one of the eight Maverick bosses from Mega Man X2.
Morph Moth is a Reploid capable of changing his own body by absorbing scraps and junk. While his origins are unknown, he joined Sigma's rebellion, taking over a robot junkyard where he uses his abilities to restore fallen Reploids using the recycled machinery in the place.
The battle with Morph Moth has two phases. Beginning in a cocoon form, he will swing while scattering junk, eventually dropping into the ground and dashing. After stopping he will dangle himself again and start absorbing junk in a circular motion, becoming larger. After absorbing enough junk or getting low on health he will pull himself up and morph into his second, humanoid phase. In this form Morph Moth will fly above the player and scatter dust, eventually stopping to fire a laser beam. His weakness is the Speed Burner.
