What villains do you think will appear in Doomsday and Secret Wars?

Classically the Secret Wars story would feature a mixture of both heroes and villains locked in a cosmic social experiment. We know what heroes will be involved more or less, but what villains?

My picks:

Doctor Doom is a given

Norman Osborn played by Willem Dafoe from the Raimi universe

Zemo from 616

Mordo from 616

Magneto played by Michael Fassbender from 10005

Samuel Sterns from 616

Thanos from some unseen universe (dies quickly by Doom)

Red Skull from an unseen universe

Eddie Brock/Venom played by Tom Hardy from 688. Likely featured in Spider-Man 4 exclusively
