I hope that if Grogar appears in the Season 10 comics but doesn’t meet the Mane 6, I hope there is at least a comic about Equestria during Grogar’s reign to the time Gusty the Great defeated him.
I don’t care if he meets the Mane 6, I just need to see what he’s like.
I’m actually fine with Tirek, Cozy Glow, and Chrysalis remaining unrepentantly evil to the very end. It’s also a lesson that some people can’t change. They chose to do evil because they are evil and we sometimes can’t change that. The best we can do is just change who we can. I don’t just my opinion.
