I managed to compile my most favorite characters from each of the five franchises I'm mainly interested in and made them into a group. Introducing… Team Harmony! In reference to my old username, Harmony—Bunny.

Ruby is the one who organized the team through travelling across dimensions with an upgraded Jewel Stick, thereby making her the unofficial leader.

Crash Bandicoot acts as the brawns, since he can spin like a tornado and has a Wumpa Fruit bazooka in hand.

Spyro is the agile speedster, being the one who can charge through enemies with his dragon horns and can breathe fire.

Pinkie Pie is the life of the party, and even thought up the team name because of the Elements of Harmony (Spyro isn't a fan of the name though), and has a party cannon stored somewhere around her conveniently.

Cream the Rabbit is the supporter/cheerleader, with her chao Cheese being the one who attacks. She guides Cheese by commanding him to do so in certain circumstances.

This may seem like a random choice of team members, but these are my favorite characters, so… Yeah. Anyway, hope y'all like.
