Mazinger Z fights to protect the Photon Power Lab from Dr. Hell's Mechanical Monsters. This is a nod to one of the Shin Mazinger Z episode, were these three Mechanical Monsters are team up attacking Osaka. I kept Ghostfire on his Shin design and colors, while KingDan I decided to keep it on the original Anime. Toros was difficult for me, because I like the Shin Design, but wanted to draw the original look, so I drew the Shin Design but painted it with the original 70's colors. The Outside of the background, the Mechas and lab where sketch - I used hard brushed and then the various natural textures in photoshop to work that background.

Ghostfire V9 and KingDan X10 were first introduced in the both the Manga and Anime.

Toros D7 was first introduced in the Manga and later Anime version of Mazinger Z vs Devilman.
