I vote for Camelia to be the leader since she has more experience in character and is nicer than Tieren.
I also put our characters initials in the team generator and here are some of my favorites I found:
BATS (Black), ACTS (Red curtain color), BAST (Blast explosion color so orangy?), CAST (White), CASA (Red but I think someone is already using this), CABG (cabbage green), STAB (Red), SASA (Salsa red).
