[Veronica Mars]

A Hulk wave could be cool, they could do a classic green Shulkie, Harpy, Classic Wendigo, Doc Sampson, Maestro, A-Bomb, Gen Ross, Talbot, Betty or Rick

Doing a 90's animated Iron Man wave would be a good way to Mass release Dread Knight, They could Include Hypnotia, Century, A new Madam Masque, Backlash. Of a seven figure wave I would guess at least 3 of them would be Alt Iron Man armors, who knows maybe the Biggest BaF in history could be Ultimo

Another FF wave would be a good way to get more Inhumans Like Crystal, Karnak, Gorgon and Triton, it wouldn't be a stretch to do Namorita, a mass release Silver Surfer, They have the teen boy body from Miles they could do a modern Franklin, they're are plenty of FF villains, They could even make Lockjaw the BaF
