Arkkadion

 Arkkadion is a Demolem from Baaldoze in Ben 10: Alien Alliance. He appears for the first time in The Next Generation by Ben's great grandson: Seth. He was used to attack Vilgax as revenge for the death of his father.

Physical Appearance
Arkkadion looks like a statue of a demon. He is 2 meters tall. His body is made of stone. His lower arms and legs are indigo, as are his stomach and claws. The rest of his body is purple-pink in color. He wears a giant black skirt, a giant black neckpiece and a black mask. He has two large claws at each limp with the same purple-pink as his main body but with indigo tips. On his head, he grows two curved horns with the same color pattern as the claws, as on his shouldes and elbows. He has bright green eyes, and small mouth. But this mouth is accompagnied with four long curved tusks (same color pattern as the rest)

Powers and Abilities
Arkkadion has super strength but is also one of the most poisonous aliens in the universe. His claws, horn and teeth contains the most painful poison in the galaxy. In low doses it can drive someone insane of agony. The mere touch is already as painful as the bite of a king cobra. In high doses it will lead to instant death.

Weaknesses
He's big and heavy, causing him to lack agility and speed. He's also lacks empathy. He will feel no remorse nor mercy for his victim and it takes a strong mind to convince him of his misdeeds.
