Umm. So I totally disagree with Muriel being gardevoir. But okay! :P
Priam...Mewtwo? I mean by a stretch. Both are kind if travelers who assemble this bing team. And both seem to be looking to reach an impossible goal. I don't know what for mewtwo. He wants to be worthy to himself which he doesn't accomplish and Priam wants to be worth to Ike.
What?! Miriel more so resembles Gardevoir than Priam to Mewtwo! She's not a sorcerer so the Gothita line wouldnt work and she's a Sage. Lol well, aside from your comparison. Priam is more like a sturdier version of Lucario tbh :P
Oh Lucario works better... Well because gardevoir is psychic, and isn't that like light magic and Miriel mainly fire magic? And gardevoir seems like she'd be more peppy than calculated to me. I am probably wrong though sorry.
