Nite Owl built Rorscach's grapple gun, so I carried it over here, too. Griff suggested the Glide power, but I don't remember him ever actually gliding, while we know he has the grapple tech.
Silk Spectre is just the same as Nite Owl and Rorschach. She never "adventured," just fought crime and killed bad guys like the other guys.
A drop power could work. I've just never been a fan of drop powers, I dunno, hah!
