Sinister is a Dark Ultra that is older than Belial thus meaning that he has been around for a while. He is the leader of the Neo Interstellar Union, an evil faction of aliens that are the successor to the original Interstellar Union.


Due to his confidence and immense power, Sinister has a calm and condescending demeanor, confident even when thwarted. Sinister prefers to use forceful actions rather than emotional words. Despite his power and authority, Sinister is respectful with his subordinates and associates being generally polite rather than patronizing. Sinister claims that he is unable to resist taking a power once it piques his interest, much like a hoarder. He also prefers stealing powers that don't require extreme experience and difficulty to master.


Sinister is a Dark Ultra that has been around for thousands of years. Not a lot is known about him. His origins are shrouded in mystery, there are theories ranging from him being a normal Ultra or even being created by an alien race. To put it simply, no one truly knows anything about him... yet.
