Born from a mortal, he was nothing but an insignificant pebble, with one thing on his mind, to become HUGE. From a pebble, he trained and committed cannibalism, becoming Bulk, then Huge, HugeXL and eventually he became Perfectly Huge, becoming Huge Incarnate. To became so he had to defeat a Huge Lady scientist, and defeat the evil mastermind behind all of this Hugeness, HugeXXL, who apparently was his father. He defeated him by eating his brain, then transforming into Perfect Huge, kicking him to the moon and burning him in the sun.
Now the only way to satisfy his hunger is by eating stars and galaxies, becoming Huger by the second.
Also, he has an amazing mullet and piercing blue eyes.
