First one's a Koopa break-dancer named Rhyme hailing from a family of various kinds of artists using their mediums to better connect with the stars.
Second one's a Toad Swordsman named Rico who got cursed with a half-shark demon form and is trying to find a way to control it (He's a partner character for Rhyme in the same campaign).
And last is a Noibat (I'm getting to that) named Pemorta who's really good at making items and has a lot more access to draconic powers than average (Though lacking in the skill to use it). She's from a different campaign where travel between the worlds of different franchises that were in Smash Bros. is possible, so I thought it'd be cool to play as a previously transformed PMD protagonist being sent to another world again to help in another prophecy that might affect the world of the former.
