Super Mira or Self-proclaimed Cat-girl
Mira got a super hero kit from her grandparents. It included this red cape and other super paraphernalia. When worn, it transforms Mira into Catgirl, defender of barbies and stuffed animals everywhere. It also makes her strike this pose when standing still, (although standing still certainly doesn't happen often.) Sid has been recruited to sidekick status, but I'm not sure he understands his role too well. Unless the evil-doers come in the form of chew toys, his super abilities probably won't help much.
