Sicko Mode is a powerful transformation in the Zerde x Jeffy fanficamatic universe. It is a form which can only be achived out of pure blood lust and mental anguish. There are only a handful of people powerful enough to go Sicko Mode at will.

Upon going Sicko Mode, the user has increased strength, speed, durability, and god like abilites. However, they will be overcome by an uncontrolable sense of rage killing anything in a 50 mile radius. Those who have mastered the ability of Sicko Mode will be able to control their blood lust and go Sicko Mode at will.
