Real Name | Spira...Squirrel? The last name was probably different once... Class(es) | Enhanced, Memetic, Generator, Dependent, Axiom, Shifter Power(s) | Toonforce, broadly applied to herself and others. Weakness(es) | She'll lose if it's funny.
Heroes often deal in concrete truths. The villain uses fire, douse it with water, rinse and repeat, pun intended. That situations broadly doesn't really apply when you're fighting with a living trope. After a brief accident involving a beat-up old camera, Spira Squirrel wants only one thing: to have fun being a hero! Aliens, magic, lasers, monsters, punching bad guys, what's not to love? Unfortunately, this leads her to acting on the first impulse that enters her walnut, usually causing more chaos than she solves and obliviously patting herself on the back for it.
Of course, that doesn't really apply to the other heroes, all of whom universally see Spira as a giant pain in the ass when she attempts to inject herself into their hero work and "help". She honestly believes she's helping too, what else would a hero do? Her help tends to leave the heroes stuck in humiliating, stretchy positions: flattened to walls as a mural, transformed into paper-thin silhouettes on the ground, inflated beyond all belief, all the DeviantArt stuff. The internet LOVES when she shows up, much to the heroes' collective chagrin.
The only positive thing about Spira's interjections is that she carries with her a sort of Tone Armor for everyone involved. Bullets miss their targets, explosions leave everyone covered in soot, and no one gets any injuries beyond the odd cross-shaped bandage or cartoonish full-body cast. She is annoying and impossible to control, but for the truly dire situations, she's good to have around. If only she didn't drop off the face of the planet whenever those dire situations were happening...
