Yeah, back in "Triumph and Torment". He teamed up with Dr. Strange and invaded Mephisto's realm. Doom "betrayed" Stephen, since Mephisto promised him he'd free his mom if he did, but Cynthia was disgusted by what her son had become, so by denying to be rescued, her soul ascended to Heaven. Doom freed Strange and they escaped Mephisto's realm. It was never revealed if he truly betrayed Stephen or if that was part of his plan, and honestly, I like that. Betraying him would break his code of honour, but at the same time, he'd been trying to save his mom for 2 decades, battling Mephisto once per year, so he was pretty desperate.
Currently, Cynthia's back messing with him and in cahoots with Ultimate Reed:

So they're probably ****ing. And considering Ultimate Reed can do this:
They're probably having a Hentai x Watchmen style orgy. We still don't know if that the real Cynthia, or an AU, Clone or Impersonator though. If it's the real Cynthia, oh boy. Doom's mother is being ****ed by an AU Reed that's even smarter than 616 Reed. And he can made his ****, like, 10 meters long and 20 meters thick. Actually he can probably create 100 such dicks... Doom's gonna have an aneurysm after going REEEEEEEEEEEEEEEEE for a full hour I think...
Did she came back to life or something?
