@Saltwater ThiefIf it was possible, I'd use the Buff Bug Ultrabeast as my Second Gijinka. The personality I'm giving the one I have is just so funny. I think I'm actually going to attempt drawing my favorite mons as Gijinka's once I find the time, since I already have ideas for them. Was planning on doing Character sheets for them, anyway, for no other reason than it seems fun, and I already have so many personalities in my head.
For Example, Sylveon(or Syl for short) is cocky as hell, knows he's one of the core team members and likes to let everyone know it. He's also a very, very sour loser. Like, whenever he faints and I get him back yup with a revive, I send him in so he can straight murder whoever or whatever killed him, if viable. If not, he'll settle for taking vengeance on their teammates.
Funny that you bring that up, actually. Seth's Dad is basically the summation of all my Player Characters from the actual games, and his primary mons are based on my Big 4 from Alpha Sapphire when I got really into the competitive side (I've used him a couple times before in previous Pokemon RPs, which is why I have a lot of his backstory filled out like this).
Celes (who you've already seen) is the Gardevoir, she's basically the Team Mom. Kind, caring, sweet as can be... but Arceus have mercy on anybody who hurts her family; she will not.
Auron is his Metagross, he's a Reinhardt-style combat junkie. Goes in, stands there, dares his opponent to hit him while he just sharpens his claws. Then, when they do and he (usually) lives, he smiles and then smashes them into the ground right in front of him.
Squall is his Greninja. Quiet, stoic, doesn't really talk much. Gets out, surveys his opponent, then takes them out as quickly and efficiently as possible. Does dabble in Haiku though, very much like Zer0 in Borderlands.
And last is Rydia, his Altaria. She's pretty much the glue of the team, holds everyone together by being friends with the lot and is all smiles and fluff all the time. But she's also the Anchor and she holds the team's Mega Stone, both for a VERY good reason.
