First up is Hightail AKA Kylie Paige Harwood. KPH natch.
She's a super speedster powered by electricity. The electric current in her powers her electricity, and meanwhile she generates electricity through her movement, kinetic or static energy. She's studying to be an engineer, meanwhile keeping her two chums in check. She would probably be the defacto leader off the crew but they don't exactly have a strict organization.
Next up is Tonedepth AKA Emile Rochard.
After considering the fact he's an anthropomorphized killer whale the size of the hulk, he has the ability to create sonic blasts from his vocal cords. He is musically influenced, having aspired to get into music production in college. His own skills involve dancing and singing, as well as being able to differentiate musical notes with perfect precision. Just don't expect him to break into song. He's kind of shy since he was involuntarily spliced into this hulking leviathan.
Finally Shadow, AKA Mathieu "Matty" Carver[Pronounced the same as Matthew]
Matty here is the youngest of the crew at 15. Boisterous and energetic, he's probably the one most needed to be kept in check by TD and hightail. He sees the two as older siblings, a stronger bond with TD as they were both forcefully transformed into their current states.
