Origin
There has been an on-going war between the Betans and Megans for centuries in which they have been using the services of war-monsters. The Megans had plans to conquer and plunder the planet Earth and unleashed three of their most powerful monsters called Krollar, Triax and Rhiahn. The monsters landed on the outskirts of Salt Lake City and battled Godzilla and Red Ronin. Krollar could burrow underground and had a powerful suction mouth that consumed large chunks of land and property. However, Krollar was defeated when Godzilla burned him with his radioactive fire and smashed his body with a few stomps.
Creation
Krollar was created by Doug Moench and Herb Trimpe in 1978 and first appeared in Godzilla King of the Monsters # 12.
Powers & Abilities
Krollar was a gigantic biomech monster which was a living creature with some parts of their bodies functioning like a machine. Krollar had superhuman strength, durability and resistance to injury. Krollar had a biomech horn that he could retract at will and would use it to lock himself into the ground as he burrowed deep into the earth. Krollar had the capability of spitting out whatever he consumed with tremendous force as a range weapon.
