Trigon is a non-playable boss character in the fighting video game, M.U.G.E.N Trilogy. He was confirmed along with many other boss characters on July 4, 2018. Kevin Michael Richardson provides the role for Trigon in this fighting game.
A sadistic, cruel, dangerous, and powerful demon of inter-dimensional origin, Trigon is a result of the mating between a female member of a mystic sect and the god they worshipped. A side effect of this pairing is that their child was filled with the cast-off evil energies of the inhabitants of Azarath, forming him into their personification. At birth, Trigon killed everyone around him (including his own mother), at the age of one, he ruled an entire planet, at the age of six, he destroyed an entire planet, and by the age of 30, he held dominion over millions of worlds in his dimension. There is some confusion regarding the origins of Trigon, as he claims to have existed as formless energy since the beginning of his own universe, while the energies cast off by Azar and Azarath simply allowed him to take physical form roughly a thousand years before DC's present day.
Arella was a depressed woman who decided to join a cult known as the Church of Blood that was trying to kill Trigon. When the ritual was performed, Trigon, disguised as a handsome male, emerged and married Arella. After making love, Arella discovered Trigon's true nature after seeing his true form. Trigon sends Arella back to Earth, and Arella is pregnant and on the brink of suicide when she is found by an extra-dimensional cult and is brought to Azarath, where she gives birth to their daughter Raven. Raven is brought up to "control her emotions" in order to suppress and control the demonic powers she inherited from Trigon. During this time, Trigon was aware of his daughter's whereabouts, but rarely intervened, except when a renegade monk named Juris attempted to cast Raven as an infant into another dimension to avert her potential threat; Trigon struck him down at the moment of the deed, and allowed the cult to keep her safe at present.
Raven learned of Trigon's intentions to conquer the Earth and vowed to stop him; she initially approached the Justice League, but they refused her on the advice of Zatanna, who sensed her demonic parentage. In desperation, she reformed the Teen Titans with several new members in order to fight her father. The team was eventually able to defeat Trigon and seal him in an interdimensional prison. However, Raven still had to fight her father's influence as he was not completely destroyed.
Trigon eventually escaped and came to Earth, taking control of Raven and destroying Azarath in the process. The Titans came together and tried to fight Trigon, but were contaminated by his demonic influence and killed Raven; this allowed the souls of Azarath to possess her and use her as a channel to kill Trigon—the demonic possession had been part of a plan to defeat Trigon, as the Titans would never have killed Raven on their own—blasting him out of existence with a beam of purifying light. Although Trigon is gone, his followers (led by Brother Blood) have tried to revive him several times.
