Maybe the bat from MTBPW went off to join them.
Do you think Nightmare Moon could take Discord in a fair fight?
1) What would be a fair fight with Discord involved and 2) Of course not.
I analyze "Geek Culture" here.
When All Else Fails, worry, that's the 14 way.
well maybe he would fight fair if Nightmare goated him into doing so.
I doubt NMM could have taken Discord.
If the CMC were superheroes or tried to be superheroes, I could imagine them attempting to solve other ponies' minor problems in a grandiose manner, like Rainbow Dash did with the lawn mowing and jar opening. And probably cause more problems in the process, given their sad track record. However, like how they got the award for comedy even though they were going for a rock concert show, maybe they would end up being helpful in ways they didn't realize? (Sweetie Belle kind of did that in a mundane way in Sisterhooves Social, especially with the way her "cleaning" Rarity's room gave Rarity a new design idea)
Pink Sugar Heart Attack!
Maybe their cutie marks will correspond to failure.
