Epidem

Epidem is the third of Innocent Zero's sons.

Due to his actions and role, he is a major antagonist in the Eclipse Arc.

Appearance
In contrast to his siblings' bizarre and dramatic appearance, Epidem is appears as a young man in his 30s dressed in an immaculate three piece suit consisting of a black overcoat and pants followed by a white dress shirt and a black tie.

His magic line is crossed over in an X-style under his chin.

Personality
Epidem loves pudding to the point of obsession, constantly praising, singing and even forming an entire religion around it called "Puddingology". Any who ruins his sweets would suffer greatly for such slights.

He is also rather polite/cunning, choosing to approach Dot and Lance under a friendly guise; inviting them for tea and willing to lend an ear to their plight. His polite persona hides a sadistic side.

Magic and Abilities
Orichalcum (オリハルコン, Oriharukon): Epidem's personal magic. It creates the legendary metal of the same name. It's the toughest metal in the world and can change its shape. It is sturdy enough to withstand Lance's Graviole.

Immense Magic Power: Epidem has incredible magic power, enough to wipe out the entire giant clan and to defeat Tsurara Halestone, a Divine Visionary.

Potion Brewing: According to Cell War, Epidem specializes in brewing magical potions that can drain a person's life and magic energy from them. It is later revealed that Epidem creates magic-deficiency viruses that drain magic from humans and puts them into his potions and even his pudding to feed it to others such as Dot.

Immortality: Epidem and his brothers got their hearts replaced by demonic ones, that can use magical energy to heal bodily injuries. They cannot be killed by conventional means, as they can regenerate at an extreme speed, as long as they have enough magic power, which will not run out due to a dose of Innocent Zero's powerful blood in their veins.

Trivia
