If you look closely, you'll notice that they're gay

First: Shout out to Maxermixer and their awesome drawings, who are the reason this headcanon started running around in my Head

Second: This has Angel Luke x Demon Joe in it, so if you don't like that either ignore or don't read

Third: English is not my first Language

So here it goes:

-luke and the daltons die after canon (or fanon if you want)

-luke being upgraded from a soul to an angel bc of all his good deads

-the daltons from souls to demons bc of their wrongdoings and respektive kill counts giving them a high enough reputation in hell to become demons

-angels being really pale and having white hair bc they are made to be pure but not as in i am better than you but bc they simply are good people

-angels also having cold bodies as the only contact they have are the souls in heaven ,which dont have bodies so they cant feel and they normaly arent allowed to visit alive humans in order not to influence them so they can be all judged fairly

(same rule goes for demons)

-but angels wings work as their halos and give off a gentle light that is warm and the the souls can feel that warmth, its supposed to comfort them, thats why angels include their wings when they hug you

(like when you are disturbed when you realise you just died)

-demons bodies are reddish bc of their heat, bc it is hell and its hot everywhere the souls down there cant get any comfort off of it (the souls are actually from bad people)

-hell is built up of different terrains making punishing souls easier, hot/cold/dry/wet

-a soul can leave hell once they realise what they did wrong, regret it fully and actually mean when they say they changed (they have to face lucifer and he knows when they are lying)

-luke and the daltons dont have their memory but the fellings stayed, they feel they know eachother but dont know why/how/when

-luke gets thrown out of heaven bc someone accuses him of having killed someone (true but that was mad jim who wanted to ruin lukes and the daltons lives completly and luke killed him for the daltons well being not his own which is found out later)

-normaly angels lose their wings when they fall but luke doesnt bc he killed jim for someone else making him still a good person

-while knocked out on hells ground a bunch of demons find him including the daltons who then put a claim on him as they have that felling that they gotta protect luke

-they bring him to their 'house' and treat his injuries

-after luke wakes up he freaks out and runs of hiding in a hole in the walls

-(hell has a part that is frezing cold and some random patches of cold spots in these wall holes)

-luke can lay down in a way that his body is on the hot ground and his wings on the cold spots, making him fall asleep

-they find him and manage to get him to get out

-over time he gets to know everyone closer including the other bad guys he had to deal with in the canon, forming friendships

-though bc i am a lukexjoe shipper they fall in love, having some funny/cute moments bc of their feelings from their past lives influencing how they behave around eachother

-giving joes brothers the opportunity to tease him for falling for an angel

-they visit earth at some point (dont have a reason yet) were they look like how they looked as humans just in modern clothes

(love luke in a turtleneck jumper, he is still cold/joe in the leather jacket)

-at some point luke gets triked to go in the cold part of hell and almost freezing to double death as his wings arent warm enough, the daltons safe him

-the hole where he hid is becoming his napping spot as he is constantly sleepy bc of the constant warmth around him

(-luke and joe have sex at some point [bottom luke/top joe] bc i want to)

-lucifer is made aware luke is with them and wants to talk to him, as he was till then the only angel that is down there and kept their wings, he thinks luke was wrongly judged and sends questions back to heaven who then find out why he killed jim and grand him entrance to heaven again

-luke is basicly picked up and send back automaticly so couldnt even say no

-the daltons try to grab him but arent strong enough and having to watch him dissapear

-the daltons and other demons protest against them taking luke away just like that, while in heaven luke is trying to get back down again but fails

-heaven and hell notice that luke is a positive influence on the demons while not having negative influence get to him

-in the end he is allowed to go back down and so are other angels to spread positiv influence on demons and souls

Luke: but I live alone!

Joe: Huh? Then who are those people in your house?

Luke: There's people in my house?
