What characters do you think deserve their own solo book?

Dr Doom-Think he had one in the past, could use another tho.

Juggernaut

Gladiator

Apocalypse

Magik.

I'm pretty content on the Marvel side. The only thing I could ask for is a Black Panther and Doctor Strange.

Black Panther. Tim Drake. Deathstroke. That's all I want.

Shazam (Captain Marvel)

Black Panther or cloak and dagger

Dazzler......
