Howard "Hellion" Fightington or Howard Fightington is one of the Zombies from the Regular Show episode "Grave Sights."
He was voiced by Mark Hamill, who also voiced Skips.
After Rigby accidentally revives all the dead people in the graveyard as zombies he and Mordecai along with the other park employees try to fend them off from attacking the audience of people for their movie night using Muscle Man's sports equipment. While fighting them Howard Fightington is revived as one too. When he emerges he looks similar to the big zombie in the movie. Due to large size and fighting skills he becomes to strong for the park employees to beat. He even proves to be too strong for Skips to beat, even when he kicks Howard in the groin, which causes it to disintegrate. It wasn't until Mordecai and Rigby finally killed him by driving a golf cart right into him, which is similar to how the guy in the movie defeated the big zombie.
- In "Exit 9B", Howard is seen amongst the resurrected zombies, however, in the next scene, the zombie boss from Zombocalypse (3D) is standing in his place.
- He also appears as the boss of World 2 in the game "Best Park in the Universe." However, he is dubbed as the Keeper of Records.
- He may be based off "The Tank" from Left 4 Dead.
