Satan

Satan is the ruler of hell and a recurring villain in jakkid166's fanfictions. He first appeared in Phoenix Wright Ace Christian as the main antagonist, and since his defeat has harbored constant resentment for Phoenix Wright and acts as an occasional nuisance for both him and Detective Jakkid166. And also Jesus, of course.

History
Phoenix's first meeting with Satan was in Phoenix Wright Ace Christian, with Satan showing up in court to prosecute Jesus. Despite tricking Phoenix into forging evidence, Satan was eventually revealed as the culprit and was somehow transported back to hell from the guilty verdict.

Satan disappeared until Phoenix Wright Turnabout Portal, where he teamed up with Manfred von Karma, Bowser, and Doctor Eggman to form the BESK team and take over Phoenix's world. They were all defeated and killed by the end of the story, however, save for Satan who survived Gumshoe's rocket launcher blast due to his immortality.

He had a brief appearance in Phoenix Wright Dank Attorney, testifying against Phoenix in an attempt to get him convicted for Manfred's murder.

Soon after, he had a brief appearance in Phoenix Wright Escaps From Hell, where he tries to stop Phoenix from turning off the Hell Generator and bringing the victims of Phoenix's earlier massacre back to life. He fails, however, and stabs Pearl's ghost in revenge - which causes her to return to life, as is jakkid's ghost logic. He then gets too distracted arguing with Manfred over burgers to prevent Phoenix from escaping.

His last appearance in the Phoenix Wright Series was Steven Universe: Human of Bad, having a small appearance near the end where he is seen "torturing" Edgeworth's ghost in hell by insulting him repeatedly. Phoenix shows up and demands Edgeworth back, but Satan refuses, leading Phoenix to call Jesus. Jesus shows up, and Phoenix leaves with Edgeworth while the two fight.

Satan did not appear in another jakkid story until The Fall of Detective jakkid166, where he is revealed as the surprise main antagonist after Detective jakkid166 and Dick America falsely believe it to be Big Macintosh. (Their reasoning being that the culprit had to be a "red guy with horn", based on the incorrect information that Big Macintosh is a unicorn.) Satan takes the opportunity of jakkid being framed to bring in his demon army and take over Ponyville, but jakkid eventually defeats Satan by stabbing him with the Sword of Demon Ass Kicking. Satan dies, but later shows up again at the end of the story as a ghost. He vows to return when he is "not dead anymore", but Jesus suddenly calls him on his phone and orders him to stop. Satan then leaves to go watch the Breaking Bad movie with Jesus.
