This is a colored version of the techno-organic Warrioir unit made and piloted by the Aggendi, a race of pseudo-dinosaurian aliens. It's from the Mekton Zeta Tactical Display, a supplement for the Mekton Z roleplaying game.
I no longer have access to the original lineart, so I had to scan this out of the book. As a result, the line quality is especially questionable. :-/
