Purple Artist is a soldier but ponies don't like him or his uniform where they'll judge him before they get to know him he just wants to blend in but everytime he stares at his reflection he doesn't see himself but a different one of him where he just wants to get a job, have a house, find a mare to date then settle down and father some foals.
Ponies will spit on him, not look at him, not socialize with him, throw stuff at him where he and his friend PFC Scmptuous a green pegasus will have to deal with the same problems. Purple has to deal with his family disowning him, sister who doesn't see her baby brother anymore, no one wants to hire him or socialize with him or just straight out kick him out and he friend Sumptuous has to deal with the same.
They fought in a warlike the Vietnam War but not based on the Vietnam war because I respect what they did they were a lot more braver then the damn hippies
