Hephaestyr

Hephaestyr (or Alex.pp) is the main antagonist from Dingus Doings and Dingus Ding Dingin'. Hephaestyr is a character made by Luigiphin for the purpose of mixing Friday Night Funkin' music to match the Dinguses.
==== Appearance ====
Hephaestyr looks very similar to Alex in all forms. In his faker form, he looks just like alex but with shadowed eyes and no A on his shirt. When he reveals himself, he looks like a lanky version of Alex with no A, fire on his head and only his left eye is visible. When he is further into his transformation, he gets lankier, more charred, has a sharp mouth and is slightly melty. In his final form, he gets lankier, is almost completley black from being burnt up, loses his "mouth", is really melty and has sharp claw-ish hands.
==== Lore ====
You can view the full (and funnier) lore document here, but here is a summary:
Alex (in the real world), left Cookie Clicker running on his computer overnight. That day, he downloaded a malware-infected mod for Friday Night Funkin' which disguised itself as a playable Boyfriend mod. When Alex went to sleep, the malware transformed into a spicy chicken Doritos Locos taco and magically appeared in a random town in the computers worlds.
For some unexplained reason, Alex decided to visit that specific town, found the taco, and ate it. This action allowed Hephaestyr, a spooky demon virus, to take over Alex's body. Alex, finding this situation intolerable, managed to separate his body from Hephaestyr's control and hid from the demon.
Hephaestyr, enraged by Alex's escape, used the knowledge from Alex’s brain to embark on a mission of destruction. He traveled to various places, including Detroit to kill Ryder, the Deep to kill Max, the Xenoverse to kill T, Green Hill to kill Zax, Hell to kill Plight, and Minecraft to kill Ben, using his fire powers to wreak havoc.
Three days later, Bobby and Ms. Xeno, prompted by Alex's prolonged disappearance, went to the town where Alex was last seen. Hephaestyr also returned to the town out of boredom and a desire to burn things. There, he encountered Bobby, and a chase ensued (Too Slow). Bobby, realizing he was outmatched, had Ms. Xeno hit Hephaestyr in the head with her bat, allowing them to escape.
Meanwhile, Alex (the person) was awake and saw the events through his computer. He opened a file shortcut to transport Bobby and Ms. Xeno to the Xenoverse to keep them safe. However, while deleting the shortcut to prevent Hephaestyr from following, his computer lagged just enough for the demon to pass through. Angered by Alex’s interference, Hephaestyr initiated a more advanced transformation (YCR).
Trivia
* Hephaestyr, being mostly made of fire, dies really slowly and painfully when in contact with water for too long.
** He normally has enough time to go to his faker form before dying, which causes the effects to be non-lethal.
* Hephaestyr has an irrational fear of apples. He pees his pants at the thought. He fears apples a trillion times more than water.
* The virus Hephaestyr comes from was made as an inside joke by the creator, but one of their friends published (which is how the real Alex found it).
* Hephaestyr is really stupid but clever.
* He is really physically weak, he can only really hurt people because of his fire and size (for later forms).
* Unless it's by water, Hephaestyr can't feel pain. He also can't feel hunger, thirst, tiredness or sleepiness.
* He has an unhealthy addiction to Story of Undertale.
