Monsuno

Monsuno hurtled through space before man existed. Upon burning through the planet's atmosphere and crashing to Earth, they brought chaos and the extinction of the dinosaurs. Over millions of years, the Monsuno essence slowly disappeared as it dropped deeper and deeper below the planet’s surface, until a scientist named Jeredy Suno at the secret government agency found a way to bring them back and control. He took his research and vanished, but not before he left his only son a special gift.
