Alya Cesaire/Rena Rouge

Nino Lahiffe /Carapace

Chloe Bourgeois/Queen Bee

Master Fu/Jade Turtle

Kagami Tsurugi/Ryuko

(These are the only Characters I know in MLB cause we didn't watch the other episodes or seasons of the series, If there's more characters in MLB series please let me know ok. That would help me out ok and to those who really like this Idea thank you so much for it though.)
