The differences with the Powerpuff Girls are that Blossom's charisma to her sisters is her ability in creating plans and leading, while Brick's charisma to his brothers is mostly about his stupid plans to make vandalism. Also Butch is unexpectedly really smart, almost as much as Brick (need to clarify lol). Butch would be the mostly silent, iperactive, sarcastic and short-tempered kid that loves destruction the most he could mostly smile when he's excited to create chaos and it would be really hard for him to show his actual feelings eventually he could learn thanks to a character development. Boomer the sensible and innocent kid, but still able to cause chaos and destruction, aka the one who shows the most love towards his brothers (Brick also shows love but is less sweet). Brick would be the charismatic leader, the 'brain' of the group, but still a little bossy and very arrogant. I agree, but I would make their personalities different.
