Fightgar
From Homestar Runner Wiki
Fightgar is one of The Cheat Commandos with a speaking part in Cheat Commandos...O's. He's the one whining about the heat despite the fact he's more naked than the rest of them.
As far as rank goes, he appears to be a grunt fighter. He has a British accent. This may be a spoof of Wreck-Gar, a Transformers character who was voiced by Eric Idle, who of course has a British accent. In Shopping for Danger, Fightgar assumes the role as spy, disguising himself as an old lady to report on Blue Laser inside the Price Style.
He also makes a cameo in a Easter Egg in Teen Girl Squad Issue 7.
