Some time ago an alien craft crashed into the Earth's ocean, injuring a coelacanth. Taking pity on the fish, the aliens brought it inside and froze it so that they might have some later project to work on in their free time while trying to repair their ship. 80 million unsuccessful years later they finally got bored. The coelacanth had its intelligence increased and was bonded to a robotic life-sustaining humanoid suit. It would be sent out from the alien's underwater base to do whatever in the world above for their entertainment. It just so happens that it decided to become a superhero.
