We need a proper Hulk and Thor. The MCU versions bombing hopefully makes them realize they can't keep up with those releases. More villains, especially on the Marvel side. I can see them doing Green Goblin, Jigsaw, Bullseye, And if they don't make a Doctor Doom, what the fuck are they even doing?
As for DC, we need to round out the League, with either Hawkman/Hawkgirl(they're subtly going for a 2003 JL series look s I wouldn't be surprised if we get Hawkgirl first), Martian Manhunter, too. Again, villains are a must, Luthor or bizarro could be easy releases.Sinestro, and more Batman villains would be nice; for all the Batman figs we have we only have 2 real villains, Joker and Black Mask(Catwoman is more an ally at this point). Two-Face and the Riddler are the must-haves, Penguin would greatly benefit from the cloth but I'm not sure if they're willing to do a one-off body for that yet. I know the owner hates Robin so not having one might not happen(which sucks, you could build 3 or four releases off one mold alone(Dick/Jason, Tim, and Damien, using variations of the 90s suit, OYL suit, and Damien's modern look, with a take on the scale-mail undies for an exclusive). I would love a Nightwing, though, with a Red Hood and Red robin built on the body later on. And I'd like a Batgirl, which you could also get mileage out of(standard release as Babs, PX as Steph, Mezco exlusive as Cass. But no more batman himself for a while, please.
