Gravel

Gravel is one of the Fundamental Four from the Special Zone. As part of the villainous team, Gravel acts as the muscle and represents the "Earth" element. Aside from his large frame, Gravel's most notable feature is that he speaks in an unintelligible language, one that his teammates have no trouble understanding.

History
Along with the rest of the Fundamental Four, Gravel spent four years in prison after being caught by the Chaotix Crew. In order to exact their revenge, the Four escaped from prison and flew to Chaotix's Satellite Base. Gravel's powers were put to use first, smashing a hole in the wall to gain entry. His next move began the battle, smashing the floor (in the style of Knuckles the Echidna) to unbalance the heroes whilst Squall shook them about. Following an attempted regroup by Chaotix, Gravel focused his attentions on Vector the Crocodile, seemingly ramming his jaw into his skull.

Gravel and the others were soon able to trap Chaotix (sans Charmy Bee) in a liquidiser, with the bulky muscle particularly keen to track down the missing bee. However, Charmy eventually found him, armed with several workers bees borrowed from The Hive. Their first target was Hydran, whose spilt water poured all over Gravel. The soggy mixture was shovelled into the passing Squall and the all thing was turned into a pot when incinerated by an out-of-controll Flare.
