ROBOSHARK RAAAHHH

Backstory: A spaceship had arrived near earth, launched 3 weird alien capsules. One of them had arrived in the ocean, an caught/eaten by shark. The shark has suddenly evolved and transformed into a robot, feeling how every inch of it's body felt a sudden burning pain, feeling how every fiber of it's body and soul was replaced by just machinery. Turning it into a control-less robot to fight.

Powers/Abilities: X-Ray Vision, Saw Teeth, Welding, Machine Guns (that come out of compartments in it's body), Super Strenght and Resistance (It's durable enough to withstand thousands of bullets and even missile strikes and as powerful enough to swim through any surface, whether solid or liquid.) and is even able to fly, talk and adapt to the movements of it's enemies.

Appearence: It used to be a common shark but because the alien teach it ate it was turned into a completely different being, made out of an unknown material and having various bright-red lights around it's body. (Despite it being alien tech it can be hacked easily, once hacked it's red lights will turn green.)

Personality: Obviously it has none, atleast as a robot shark. Being just merciless and murdering everyone and everything in it's pact. But when the spirit of the once organic shark manages to take control it tries to give proof that it didn't want to be like this and that it wants to be free. Constantly trying to get control of it's body.
