Doomsday vs Earth 616 (Read OP)

Cyttorak decides to give his ruby ​​to HP Doomsday and then sends him to Earth 616, how much destruction it causes before it is stopped ?

Really depends on how much power Cyttorak gives him, and how intelligently Doomsday uses it (he used the GL ring iirc).

Otherwise,yeah he gets BFRd
