New 52 Cyborg Superman vs Doctor Doom

Doctor Doom knows of Cyborg Supermans existence and is prepared for battle in this instance but doesn't truly know of his weakness. Cyborg superman has no lantern rings.

Cyborg superman enters latveria and wants to take over.

Morals are off,fight is till death who wins. NO BFR.

@batmanfanboy: Cyborg Superman doesn't have any Lantern rings in the New 52, he's an entirely different character.

If you mean Hank because you mentioned Lantern rings,then Henshaw takes over Doom and Latveria
