Sekiro x Overlord- Yeah Wolf normally would't able to hold his own against Monsters who are literally OP, but what's to happen IF he could hold his own against them? I'd think it'd be pretty interesting thinking about it.

Devil May Cry x Overlord- Basically me thinking about Dante comboing the absolute shit out of Nazarick. Like the Sekiro idea, Dante would be overwhelmed by monsters who are again: OP! But what no better way to fix that than to buff him up a bit? Though, only enough to be able to hold his own like always against the demons he's fought all his life.

Gintama x Overlord- Gintoki is a Nine Tailed Fox, and also straight up Lv 100. He still has his wooden sword that now can tank ANYTHING! Even World Class Items maybe... He's still stupid though. I personally want this crossover to happen because you got a guild which most of its members are edgy, then you got some silver haired bum who's basically not bothered by anything. I say Nine Tailed Fox Gintoki because the normal version of him would be scared shitless, and his plot armor is basically futile to penetrate through because why? Because of course, he's the protagonist of Gintama! Enough said!

Warframe x Overlord- OC with the Gamer ability Overlord with Warframe mechanics, Equipped with Excalibur Umbra along with the Skiajati and Tatsu.

These are all the ideas I have so far. I'll probably have more later.
