Steven Universe Secret Wars: Battleworld poster

"Following a heavy loss as a result of the titanic battle against Thanos, both the Avengers and the Crystal Gems are torn apart out of grief. But when Thanos reassembles them to fight to the death on his personal Battleworld, Steven, Garnet, Amethyst and Pearl are now in for the fight of their lives."

This is it, the final part of the Thanos saga, and this isn't even half of the cast! Aside from all those listed here, we got the other heroes introduced in Part 1 and a few others that I won't talk about because of spoilers.
