Team Boss! Angel Motherboard

In Angelbloom each team has two "team bosses" who are magical girls from the previous team. When a new team is made the old team leader and one person of the old team boss's choosing becomes the new team bosses.

Angel Motherboard (real name Spark) uses tech/electricity themed powers.

Bonus: Also transfem. Angelbloom has a lot of transfem characters lol.
