Miss Adventure!
Eccentric adventure junkie cat-girl with portal powers

Miss Adventure is a young superhero who sometimes goes by the name Mittens.  Perhaps because she's a few kittens short of a litter, or perhaps because she looks like she's part cat and thought the name cute.  ( picture https://www.deviantart.com/timothius/art/Mittens-Starwars-framed-659857665 ).  Relentlessly cheerful, energetic, and often eccentric, she an adventurer's adventurer!  Whether it's challenging the world record for the most flaming sharks juggled on a unicycle tightrope ride over the grand canyon, or saving a kidnapped baby from a communist vampire castle riddled with explosive traps and swarming with flying nuclear ninjas, there's never a dull moment with her around!  Mittens hasn't told anyone the reason for her strange appearance or what the source of her power to make flying physics-defying portal discs appear from nowhere is, but you can be sure she'll be having a hole lot of adventure making villains drop into the pitfall of justice!
