Catharsis user

A catharsis user is an entity that has the ability to both focus their anger onto their strength and enhance their adrenaline rush at the same time. A user that does those two enters a state known as catharsis, and both abilities are collectively known as the catharsis abilities. Due to the combined strength of focused anger and enhanced adrenaline rush, it is a law of nature that most entities cannot have both abilities at the same time. Catharsis users, as such, are very rare, even across other universes.

Catharsis users can fuse with one another. Upon doing so, the strength of both entities are combined, with the power of their focused angers and enhanced adrenaline rushed squared. The result is essentially an entity that can be much, much more powerful than even a lower deity, and can even match the power of the most powerful entities in the entire Multiverse.

For an entity to be able to use the catharsis abilities at the same time, they must unwillingly go through a devastatingly horrible life-changing experience, though it is highly unclear as to what is considered a devastatingly horrible life-changing experience, thus not many people, even if they end up miserable in their life, gain the catharsis abilities.
