Abaddon

To solve the problem of rouge demons, scientist created a defense robot just in case. But no ordinary robot, for it has a miniature black hole inside of it so that it can really dispose of it's targets as well as devouring everything for a significant power boost. But it also came at the cost of said robot to weigh more than it looks. So the scientist programmed the knowledge of gravokenesis in him. They also gave the robot nanobots for extra locomotion and superb flexibility as well. These nanobots will always return to the robot and if they get in someone's bloodstream, they'll always aim to destroy the heart on the inside but for allies, heal major wounds and reattaching cut limbs. After it was finally completed, they named the robot Abaddon the Devourer . After the angel of the abyss.

Weaknesses - Slow, nanobots take time to regain, is still affected of suction, powered up state lowers defense, arrogant

Strenghts- Body can produce more nanobots to replace lost ones, limbs can mold into anything like spears, hands, and axes, Defense strong enough to survive the suns core, Gravokenesis
