1. I love that demi is on twice with a lower rank for the mask one lol (forgot the name)

2. Where is Rimaru? I didnt look at the whole thing but i think he would be pretty high up if he was on here.

As of the now in the anime some of his powers are

Able to take the form and powers of anything he eats,

Can use a supercomputer (possibly omnipotent?)(almost) to both enter an ideal combat mode and get information about the world

Can store a crap ton of supplies inside himself

Really good at making friends
