The Horsemen

Powerful Creatures from beyond Japan, Earth, or even HARVEST. The sworn foes of COURAGE.

Famine
The driving force for the destruction of Earth, Famine seeks to devour all that exists within Infinity. Now that Courage is gone, he drives relentlessly to expand the breach and take over Japan, followed by the rest of the world.

Through the use of The Pact, he owns the souls of every single user of Courage, to what end he needs them for, or why he does not simply wipe them out of reality if he truly controls them, is a mystery.

Malice is Famine's trusted Herald, Malice stands to spread Famine's will. However, the Lich has his own plans, and usurped control of the position of Horseman from Famine during the season 3 Finale. Now, Malice holds control over the fate of Japan. Though he kept his word by letting Reo exit The Pact, he easily tricked him into taking it again. For whatever reason he has, Malice continues to carry out Famines original plan...

War
Once the driving force for the destruction of reality, War has been silenced when delt a death blow by Courage. Now War is paralyzed, unable to rise from his throne when he sat to rest off his wound. His servants search endlessly for a way to bring their master back.

The master fighting Lich, Slaughette, serves War, rumor has it that she's slotted to be the primary antagonist for season 16, but no official source has confirmed it.

Death
All that is know about death is know by his servant, Fane, who comes to battle Malice for killing Famine. Fane is a Lich with no magical abilities, but a near total resistance to magic, and the ability to ignore any physical damage. Allegedly, Death wanted no part in the plan to take over Earth, simply wanting to end Courage since he could not stand a being that stood to live forever. This implies Death is the most passive of all the Horsemen, and as Fane said, "He [Death] own all, eventually, why would he rush anything?"

Pestilence
Pestilence is rumored to be on the horizon, still being the only Horseman without an introduction yet in the series, fans rumor his arrival in season 16.
