Demon King

Oliver is a major antagonist in JAFT 2. He helps Raven in her plan to collect the Magnum Rifts and create the Colossus into a mecha-doomsday machine.

Basics
Oliver has white shaggy hair and wears a turquoise lab coat and shoes. His skin is overly pale, unlike the rest of his family. His weapon of choice is a double-edged sword with demonic runes etched on its surface, which give it power. He uses this sword to fight Jeremy in the Force Sanctum. Later, when Jeremy encounters Oliver in the Colossus, he fights the group again. This time, Oliver transforms into his more powerful form which grants him more powerful abilities. In this form, the runes on his swords glow red, and the swords become detachable. Oliver also ditches his lab coat in favor of black and gold armor. Energy from the souls of his victims flows through his veins, as indicated by the skulls with green circling around them. He wears a silver crown, similar to Demon Queen's gold crown. During the second fight, Oliver has incredible power and almost defeats Jeremy again, but Kitachi comes in and delivers the final blow.

Abilities
Oliver's main offensive spell is Iron Spike, which does a modest amount of damage but takes a handful of magic to actually cast. He can also cast Metal Trap, which binds an enemy in place. His strongest magic spell, Iron Soul Nexicon, can be used to deal heavy damage to all enemies. Besides magic, Oliver can use his double-sided sword to deal heavy physical damage to multiple enemies at once. He also has a wide variety of healing abilities.

When Oliver reaches his second form, his power vastly increases, although his move set is pretty much the same as before. His swords can now discharge electric energy, and he can sand the swords using the blood of his rivals. His soul energy, represented by the skulls on his shoulders, can be used to replenish his health and magic.
