I do see potential...
I don't care for Mecha anime stuff, so that'll be out. Throw out the villain and pets. Less kiddy plots, spaceships etc.
AND FOR NICE THINGS:
Give it an even sharper edge.
More sex jokes, themes, and references
Make it like Animaniacs how it pushes the envelope
More nice Frenchie music
Mature themes of living in the city
Charlotte a main character,
More of her friends, lots of pretty girl main characters
REAL JOBS + CAREERS not superheroes
Adventure and high stakes, with fear of death
