Unicron

he has many names: the destroyer of planets, the chaos bringer, the world eater, but his real name is Unicron. he is the biggest transformer ever, he transformers into metal planet that devours other planets. he is yellow, perse (grayish blue). his are glowing green. he has two horns on his head in robot-mode. usually he is in planet mode and travels across the space and galaxy. you can be anyone. Unicron is property of Hasbro and Takara Tomy. He is usually calm, kinda toxic, he is the world evil, so he can resurect and repair transformers, and if you live on planet he plans to devour, you better leave it before he comes. if he is angry, then it's nearly impossible to stop him, he will destroy everything and everyone, so you are better not to annoy him.
