Akuma is an alternate version of The Bloody Biker and a portrayal of The Fear of Anger seen in the blog Horsemen. Unlike the Bloody Biker, Akuma is considered a Fear in the Horsemen universe and represents the Fear of Rivalry. He will do whatever it takes to kill anyone that is considered to be more powerful than him.
He was once the rival of Dragon Slayer Jack until he finally managed to kill him in The Cliffs of Suffering in Netherworld five years ago. However, years later, Dragon Slayer Jack somehow came back to life or faked his death and has began thwarting all of Akuma's attempts at killing the children of the Horsemen.
Akuma rides a motorcycle which can be melted and reformed into any weapon he wants. Like the Bloody Biker he wears a blindfold, and is often seen wearing satanic symbols.

- Satanic Seal 1 - Fireball: Fires a huge destructive fireball.
