I kind of want an Yu-Gi-Oh! AU where all the yamis and hikaris have their own bodies and are having a game night at Ryou’s. That have played all sorts of games together over the years but this is the first time they have all agreed to play D&D.
Ryou is the DM and everyone else makes characters that happen to be similar to themselves. Each one having different alingments they feel they can relate to or just think would be fun to play as.
Yami takes Chaotic Good.
Yugi is Nutral Good.
Malik takes Chaotic Nutral.
Bakura takes Nutral Evil.
And evenyone just stares at Marik’s sheet as he had written Lawful Good on it.
Some of them laugh, others roll their eyes, and Ryou just smiles polity.
No one believes Marik can even pretend to play the role of a Lawful Good character. Ryou isn’t even sure but to be fair he just wants to go the game going and is curious to see how each of the players will take their roles in this world he has made.
Time goes on and everyone has played their parts rather well till they go up against an enemy that has beaten the gang and tossed them around like a bunch of ragdolls. Surely they know they can not win this fight. It has been fairly one sided and they are meant to regrope and fight his foe later.
…Then Marik does something no one saw coming. He prays to his god and attacks. Natural twenty. The fight goes on. Marik disarms the villain and instead of going for the killing blow like everyone assumes he will do, he picks up the fallen weapon and tosses it back to them. It’s not a fair fight if they aren’t armed and his alignment refuses to allow him to strike a unarmed enemy. Besides, what fun is there is the villain does not struggle for his last breath?
Instead of fighting further, Ryou has the villain take his weapon and vanish.
The party is dumbfounded. Marik isn’t playing as they expected him to. He’s nothing like his character and yet he is playing honorably? What madness is this?
The game is continued at a later point in time. Everyone curious as to what will happen next but none of them say anything to Marik as he reveals that he is actually pretty decent at getting into the mindset of a Lawful Good character.
This same campaign has gone on for a month now and while they party has had it’s rough spots, they managed to stick together and defeat whatever Ryou threw their way. After all, it’s no fun if they don’t get attached to their characters before you kill them off…

Eh, anyway… Maybe I’m just being weird. I just really like the idea of Marik seeing himself as the good guy doing things for ‘the greater good’ even if that means having to get his hands filthy with blood so the ‘bad guys’ suffer and get their just desserts but I’m a sap for that kind of nonsense.
