I made this challenge on an idea that came to me
What If Marco was an descendant of an Queen of Mewni(any of them Is fine)
Rules for this challenge:
1:Marco can use magic(In this case he would be related to a magic using family after all)
2:Pairings(can be any(though I'm a huge starco fan))
3:Marco can either already know about his heritage or discover little by little when Star comes to earth)
4:The amount of power Marco has depends on you(he can be OP, strong or whatever)
And finally If you plan to accept this challenge PM me about It so I can wait for the first chap.
