Not too long ago I talked about the Monstroids here. It was always odd that there was a groups of 'evil transforming robots' in the cartoons, but in the toy line Monstroid was an individual robot monster who worked with the Evil Horde. If you've never seen him, Monstroid is a really large toy that looks like a crab. The top half spins around chaotically which make the body rock around. Said rocking makes Monstroid walk around on his long legs in whatever direction gravity takes him. Stick a figures arms or legs in those claws and watch them be flung around like rag dolls. It's pure insanity and maybe a broken lamp if the figure flies loose from the evil grip of MONSTROID.
The big guy didn't get much fiction time aside from random art appearances. However he did show up in a comic story in which The Evil Horde summons him from Sea of Rakash. Under Hordak's magic spell, Monstroid attacks He-Man and Skeletor. Orko and Extendar save the two and Multi-Bot is eaten in the process. It's nice that such a chaotic toy is just as out of control in his fictional debut. I like that without a doubt, Monstroid is a monster. He's aligned with The Evil Horde, but that's basically thanks to a spell. In any other situation, there's just a giant robot-crab thing that's going to kill everything in it's path. I also like the fact that a living robotic creature that lives in the sea without any explanation and we're just supposed to go with it. Pure chaos on every front.
