Invasion.

A mysterious rift has opened a small crack in the universe it closes in thirty seconds. Dr. Doom and Reed Richards are now trapped in the DC Universe. They put aside theyre differences and decide to take over. They have 18 months of prep time. No one is aware of their presence and the rift gave them full access to Cybertronian technology minus the transformers. Say an invisible city the size of london underneath the ocean. Can they succeed?

Against the entire DCU? Hell no.

But they could certainly do some damage

How much damage?

With that much prep they create a global mind control device and makes the heroes kill each other.

No.

At some point, Phantom Stranger ninjaz their tech, then disappears.

If it was full access to kryptonian Technology i could see them conquering all of earth.
