Vomit leaves on a long boat from America to Japan and hides there, as he is depressed and ends up in the city were the suinami occurs at and he is washed away and in pieces. his acid body rots the core then, he reforms in the nucelar reactor and gets the japanese army and navy spray him and he falls in the hole, his body created and he mutates and becomes radio active or nueclear enabled and when things came down, he climbs out, with a throbbing headache and glowing eyes and more limbs and much more mass.
He'd look to people who have seriously wronged him in life and start out by taking revenge, but he is actually gentle.by nature..so he picks his battles carefully but, prefers the seagulls and rats as they do not judge him. and his two headed dog loves him too.
But he changed similarly like hulk and looks hedgehog most of the time, but when he has to do damage or in a fight he changes total size shape.
He is a monster of sorts.. and mutant. and his sickness causes the nuclear wall to rot and he fell in when the sunami occured and him getting sprayed and when he reformed, he was radiation active and mutated again when he climbed out.. so as well as a big headache, and sickness, he got a cold soaking..
Think when Martin from The Simpsons made a small power plant which was powering the building.
so a radioactive mug of water.
[well if you read the plot, his vomit and stomach acid rotted a nuclear wall and he fell inside. and became radioactive]
Meshronic "I say not to wash me" [yah good plan there..]
