Sting Chameleon is a minor antagonist from Megaman X1. He is a Reploid who was part of a special battalion of the Maverick Hunters but once Sigma's rebellion began, he sided with him for the sole reason of "Leaving his mark" likely to prove his worth. He oddly enough shows some form of respect for criminals like Vile.

He is a green reploid modeled after a chameleon, even his left eye is designed to resemble one which is also likely created to act as a zoom lense possibly. He is designed with climbing in mind as he has 3-digit suction fingers. He sports spikes along his back and a flexible metal tongue and tail, the latter which is spiked at the end.

In his arsenal he can lash out with his tongue and tail as well as utilize Chameleon Sting which is a later that can split into 3 more. He even possesses the chameleon trait of going entirely invisible.
