Underrated Character From Ben 10

Exoskull is a villain created by Dr. Animo who has fought Ben 10,000 before. He is a cybernetics enhanced rhino/human hybrid, and part of a gang of human/animal hybrids. He is also one of Maltruant’s henchmen. Exo-Skull seems to be surprisingly intelligent, even though he likes to skip the fancy stuff and focus on smashing things. Exo-Skull has enhanced strength and endurance due to his large size and cyborg form. He is strong enough to overpower Four Arms and Rath, and easily smash through walls. He even can destroy some of Argit’s Techadons, even without the Dwarf Star in his possession. Exo-Skull can shoot energy blasts and nets out of his horn.
