Grisha
Name: Grisha
age: in human years would be 29
about him: Grisha may seem like an asshole at the first sight and oh yes!,he is!.Grisha is very self confident,astute and LOVES to do bad taste jokes,be extremely sarcastic,and especially annoy too serious people,like Roth.He knows a lot of things,he has read about humans all his life,and knows more about humans that humans themselves(because books of other dimensions are better(?)).He always have a BIG and large smile on his face,he is really difficult to bother because everything is always under his control,because he is very intelligent and knows a lot how to manage things to his self profit.
Although he seem he only likes to annoy Roth,mostly he is teaching him about life,because Roth hates doing stuff by himself.So Grisha give him problems and obstacles to surpass and learn from it.But sometimes he just wants to annoy(?) and using his knowdledge about humans he can make Roth go from extreme panic or fear to extreme pleasure.
Grisha can take many forms due to his body shadowy made of a weird material.Can take a human form,cat form,even more monstery look.And many others.
