Charybdis is only known for one thing. Making AQ lose a hand. As a villain he had one power suited for taking down powerful metas, draining their powers, and it worked well for that story. But unless Parker can connect the character to something equally memorable (like the hand loss), I don't believe we'll see much of him.
Qwsp could work, but I doubt it since there's Mxy already in the New 52 and I'd hope for more villains unique to Aquaman.
