I was wondering who the mane 6 would be under king sombra reign and if he would be redeemed in the process. Right now I’m thinking radiant hope should be the leader

Nah, King Sombra & Radiant Hope are like Star Wars's Anakin Skywalker & Padme, as Radiant Hope is there to keep Sombra's dark side checked and keeping him on good. ( I haven't read the comics. )

Yeah in the comic he was a umbrium creature turn into a pony to free the rest of his people.
