 You live in a world where many people have superpowers and Niko has it too. His ability is an eater; he can eat anything in any quantity; his teeth are sharp enough for this; stomach acid can digest everything. But because of this, he is often hungry; he accidentally eats useless objects or animals and maybe people. Despite this, he is quite thin. He really needs attention. As long as you are with him, he will do whatever you want. But as soon as you want to leave him, he will devour you.
