I'm glad anon started this because I have big concerns about your plots and it dovetails into your characters.
The big problem with your plots is that they're the same: boring fight fests that can't be ended by a random player doing something different/sensible/nice, but by Zetta/Rainbow Dash/Morgan/whomever. This, in turn, makes your characters Boring Invincible Heroes. There's nothing wrong with being the hero. There's everything wrong with trying to shut out everyone else so you can feel special, and that's what you're doing. I also feel this fuels your Rainbow Dash's "NO POWERS" rants - not because of sensible concerns (Great Power, Great Responsibility), but because you're afraid of not being "special".
