Comparing doesn't have an "e" in it, er, maybe edit that.
AJ as Toru? Aww maybe in a few episodes, like Applebuck Season. Toru reminds me more of Fluttershy because they are both so super trusting of everyone.
There are a Sailor Moon and Jupiter pony that are background ponies in the comics, well... not in their outfits, but still make cameos. Speaking of that anime Sailor Mercury/Ami and Twilight, both totally into books and clueless socially in the beginning of the series.
Ah I forgot the last bad guys name in Kaze no Stigma, but he reminds me of King Sambra, essentially willing to sacrifice everything for power. That anime was so bad.
Twilight also reminds me a lot of Madoka from Puella Magi Madoka Magika, in that she just wants to help others, but Madoka is sort of stupid so it is kind of lacking in that trait. Mami from that show reminds me of AJ, and Kyoko is a lot like Rainbow Dash.
