The Fantastic Four wave will include the Four (Reed, Sue, Johnny, and Ben) in their more modern black-and-blue costumes, as well as Dr. Doom (with both modern and classic masked heads) and She-Hulk (post-Civil War II 'Grey' Hulk form), with the BAF being Kl'rt the Super Skrull!

Reed comes with regular and 'salad finger' hands, and features his bearded look; Sue includes an invisible force field attachment, and has no "half-visible' body parts, unlike the Walgreens version; Johnny is NOT in 'Flame On' form, which really differentiates him from the Walgreens version; Ben has a new head and belt, but the alt hands from the Walgreens

version should still be swappable, since it's the same mold otherwise; She-Hulk, given the version, is being advertised on the packaging as just The Hulk; Doom comes with his iconic pistol that he NEVER USES; Kl'rt, long rumored to be a Walgreens exclusive, includes a maniacal grinning face and alternate F4 power arms

We know that Doom is one of the double-packed figures for the case

The Spider-Man wave for Spring 2020 features two Gamerverse Spider-Man figures (Velocity Suit, and Spider-Armor Mk III, from the "Ends of the Earth" storyarc), Superior Octopus, The Vulture (classic version), off-the-wall villain The White Rabbit, and SHANG-CHI, THE MASTER OF KUNG-FU! The BAF is the Demogoblin

No idea if the tentacles on Superior Ock are bendy or not; Vulture includes a hooded head, if you're into making him look more ridiculous; White Rabbit is ACTUALLY BEING MADE!; Shang-Chi has enough alternate hands to make some import figures jealous; Demogoblin, surprisingly, isn't a reuse of the Hobgoblin BAF from a few years back - rather, he's a retool

of the mold they've used for the more recent Hobgoblin/Green Goblin figures, which means he was reverse-engineered into a BAF (which the team has said is actually less cost-effective than even doing a new mold)

Additionally, the teases for next year's waves included

The full reveal of the Strong Guy BAF for the next X-Force/Deadpool wave (we'd only seen CG renders up to this point, not hard prototypes)

Comics-style Winter Soldier and Spymaster, likely a part of the Black Widow movie tie-in wave
