And sometimes humans want too much, go too far. He was a victim, a creation of cruel underground experiments. Made up of dead body parts in a frankenstein manner as well as robotic parts, only to become someone's favorite hobby - and an unholy being that should not exist.
In his world, robots androids and cyborgs are common, but they all look friendly and humanoid for the most part - nothing quite as extreme unless you go to the worse parts of the city where people are desperate and lack the cash for high quality parts.
Although this is the case, desecrating the dead is something that the law forbids.
His brain after being brought back in his new body was weak and slow, leaving him without much of a personality or thought at first.
Like a child he has to learn again. He is mostly passive unless something strikes his interest.
He has no interest in causing harm, but can be very determined if he wants something.
Eventually, he starts remembering bits and pieces of his past - potentially due to his brain being the only part "alive" for the experiment that created him. He will then have to face a cruel reality.
He has 3 hearts, 1 of which he could technically exchange himself.
He does not have toes anymore
He can't speak well due to his missing lips, but he can write and gesture. Eventually, he might get a voice box implanted.
He does not need to eat, he gets nutrients via tubes in his back.
His breath is really really hot.
When he gets emotional or unsettled/upset, he grows double his size (see image 1). It takes a while of being calm to get back to normal (aka still two people tall).
Yes I will throw a human at him, open for suggestions cx
