Butt-Ugly Martians - Enemies

Enemies

Emperor Bog - (S. Scott Bullock) The evil but foolish ruler of the Martian populace, Bog is often fooled by the Butt-Ugly Martians' fake progress reports. He has little tolerance for imperfection, his idea of perfection being everything going according to what he wants. In short, Bog is little more than a whiny spoiled brat. As the show progressed, Bog became more suspicious of his "loyal subjects". He likes to roll his R's. He is incredibly lazy, admitting to not even having to pluck his own nose hair, but for some reason has prominent abs and pecs.

Dr. Damage - (S. Scott Bullock) Bog's more intelligent right-hand-man, Damage constantly suspects that the Butt-Uglies are up to something. He's usually right, but rarely noticed. Damage (pronounced "dah-mahj") invents many instruments to conquer Earth, but these usually lead to the Butt-Uglies destroying them and making Damage look like a fool in the process. He constantly insults Bog behind his back, despite Bog usually hearing him, and so always has to make up a compliment that sounds vaguely like what he was saying (e.g. "Royal nincompoop" becomes "loyal troops" in the first episode). He has also, on some occasions, tried to overthrow Emperor Bog as Martian emperor. However, Emperor Bog eventually found out about this ambition and, as Damage's punishment for his attempts to take over the position of Martian Emperor, made Damage wash and wax every ship on their base, and had Shaboom and Infi-Knight watch him to make sure that he did the job right.

Jax the Conqueror - A warlord who despises Martians, but after being defeated and imprisoned by B-Bop and the others pretends to be willing to help them invade Earth to get a chance for revenge. He pilots a ship called the Doom Jax which is impervious to Martian weaponry. He has been "destroyed" three times in the series run, but always manages to come back.

Humanga - A giant alien villain who is the only player of an alien game called Toget. Humanga has won as many games as the Butt-Uglies themselves.

Infi-Knight - A four-armed robotic warrior created by Damage to speed the Earth invasion along. Probably the Butt-Uglies' most powerful enemy.

Koo Foo: - The last surviving member of an alien race. His race was an evil species that tried to conquer the whole universe 2000 Earth years ago before mysteriously vanishing. His crashed ship was submerged in the desert and believed to be a pyramid due to its shape. Muldoon accidentally released him at the same time the Martians arrived to destroy him. He took Angela to save her from danger but the Martians thought he was kidnapping her. It was eventually revealed that Koo Foo was not evil like the rest of his kind and had left the swarm of ships before crashing on Earth. He says he does not want to fight or hurt anyone. The Martians do not believe him until Angela points out that they themselves are different from almost all of their species. Koo Foo leaves in peace. He reappears as a one - off at Do-Wah's birthday party in the comic series.

Gorgon - A fire-breathing lizard-like alien characterized by the ability to change into or possess others and a TERRIBLE smell. He speaks with a hiss.

Klaktor - A Reconabot (portmanteau for "reconnaissance robot") that the Butt-Uglies defeated in the first episode, though he reappeared later in the series. Can fall apart and reassemble himself at will. This trait turned into a common sight gag; his action figure is equipped with ejectable arms.
