Vexor
The leader of the Magnavores, he looses his patience with his Magnivores' incompetence. He was destroyed briefly by the combined efforts of all three Beetleborgs, after Drew battled with and destroyed Shadow Borg. He quickly revived himself, sprouting a new body and face and managed to grow giant. In his following appearance, he somehow switched back to his old appearance.
Typhus
A monster with a strong upper-body, he prefers brawn over brain. His flattop acts as an extra mouth with which he eats food or other objects. In battle, he sometimes wields a sword-like weapon that latches to his arm or his mouth. This weapon can also blast lasers when shoved into his extra mouth.
Noxic
Android that can control machinery and other objects by removing his head and attaching it to them. In a dream of his, he took control of a bulldozer with his head and tried to destroy the Beetleborgs. He later used this same technique to take control of Ghoulum, when he went bad from the comic book's formula. He has an unseen wicked friend, from the comic books as well, named Dr. Cackle, who created the evil formula. Noxic prefers to eat donuts all day long instead of doing Vexor's bidding. He has an older brother named Super Noxic, though technically Noxic was created first. In battle, he sometimes wields an umbrella-like weapon.
Jara
Female humanoid clad in red attire and a white mask, who speaks with a Russian accent. Despite her face being remade 3-dimensional, she cannot consume food or smile in the real world because the mouth on her mask could never open. She was bitten by Wolfgang one time and became a werewolf and enamored with Wolfgang, but was returned to her normal form and retained none of her affection for Wolfgang. In battle, she sometimes wields a whip that when cracked releases destructive energy.
Magnavore Jet Fighters
Air-borne, wasp-resembling machine jets. Summoned to attack the Beetleborgs on several occasions, when in their A.V.s.
Scabs
Yellow-black footsoliders dispatched rarely against the Beetlborgs.
