So in my AU this would exactly happen, but it's gonna be different, so this is gonna be before they went to see the rings of hell council or something like that, where striker was gonna pull up with an army who had been hired by a mysterious person and the whole crew was gonna be there (including stolas and Octavia)

My AU character kris Dreemurr aka the fallen knight, now a detective of hell, would try to handle the situation but it would gone worse, and since he has a Demon inside of him, because he's a goat devil, and if anyone hurts someone that he cares about, then he goes batshit full on goat devil mode, and I forgot to mention that this au is combine with another au I made, and what au is that...

It's an UT/DR AU called futurerune, I'll explain that another time

So when kris turns into his final form, his howls echos not from hell, but heaven and earth, even the dark worlds, and with that howl, an old friend knows what that is....

The legend of the Grey goat devil's howl...

Kris now the Grey goat devil as he tries to protect his friends from death...

A double edge axe swings appear killing the soldiers that striker has and that double are

Is susie's....

But another appears as one freezes the other soldiers and that being the cryomancer Noelle holiday, and the green prince turned wizard heals the Grey goat devil wounds, and that being ralsei, and another uses a techno clones distracting the soldiers to free the I.M.P and the two owls, and that being berdly (bite me he's goated), and last one being a queen in heavens wings and a queen to the king Grey goat devil, that being frisk (female) dreemurr, all five lighteners united as one to stop striker and his army, but when his army is done for, he brought back up, the exorcist....

So know the Grey goat devil (aka kris) knows that he knows he hired striker to execute and kill them, the general of Adam now a leader of the exorcist...

Lute...

She hired striker to take a whole army and to kill the ones who are friends of kris Dreemurr aka the fallen knight...

But the battle...

Will live on...

In...

Kings and queens, part 1 and part 2....

( that was a long one I made so keep in mind, this is only the AU I made, if I do make the full story I would have to start season 1 being hazbin hotel and season 2 being helluva boss and the final one being season 3 the last knight

also I will do the same thing for my other connected AUs futurerune and Futuretale and it's prequels undertale determined souls and UnderRune mirror match)
