Grrkek is a giant alien lizard monster capable of mass destruction. He has killed millions and destroyed entire planets, and he cares for nothing but destruction and misery.
Biography
Breakout
Grrkek was sealed away long ago for his crimes against the galaxy. Because no physical prison hold contain him, he was digitized and rendered immaterial, his digital essence stored inside a device resembling an old video game cartridge along with many other monsters. Grrkek was released by Coop when he was testing a new game, not knowing it was a containment cartridge. Coop fought Grrkek and then blasted him with an energy weapon, but this only caused a cocoon to form around him. Thinking Grrkek was defeated, Coop turned his attention to the other released monsters, which he finally subdued, only to find Grrkek emerge from the coccoon transformed into an even bigger and stronger form that easily shrugged off Megas' direct attacks.
Grrkek was finally defeated when he got caught in a tidal wave which Coop had caused; the cold ocean water sapped his strength and he lost his size and mass. He is now trapped in a "Love Those Lurps" game console cartridge, which greatly annoys him to no end.
Personality
Grrkek is very cruel, arrogant and sadistic, caring for nothing but destruction and misery.
Abilities
Grrkek has super-strength that rivals Megas when he was released from his prison. If hit with certain energy weapons, a coccoon will form around him and he will enter a dormant state but he eventually emerge even larger and stronger than before. By placing both hands together Grrkek can also power a nuclear fusion orb that can, at a minimum, devastate a city-sized area; in his larger, more powerful form, it is capable of destroying an entire planet. Grrkek's size and mass vary based on how much energy he has absorbed. Even at his normal size, his combat skills proved to be difficult for Coop/Megas to handle. His weakness is apparently water: large quantities of it can extinguish his fusion orbs and shrink him into a much smaller, weaker form.
