I picked “eighty-foot wolfgal” when I was designing* Trouble because it rolled off the tongue, but it’s been fun forcing myself to work within that particular framework. Seven stories is far from unfathomable, but a seven-story critter can cover a city block in ten steps and pick up a car like it was a can of beans. She’s large enough to be powerful intrinsically, but small enough that she can focus it at a specific person.
