Emperor Vulcan vs. Doctor Doom
This fight will have two rounds.
Rnd 1 - Vulcan and the entire Shi'ar Empire invade Latveria to take it over. It is a random invasion. Doctor Doom was never prepared for this. Will Latveria be able to survive and win the battle, or will Latveria be taken over by the Shi'ar Empire?
Rnd 2 - Same scenario as round 1, only this time Doctor Doom heard from an anonymous source a week prior that Vulcan was planning on invading, so he takes that entire week to prepare Latveria's defenses for the invasion of Vulcan and the Shi'ar Empire? Will Latveria be able to survive and win the battle, or will Latveria be taken over by the Shi'ar Empire? What will Doom do to prepare for the invasion? How will be combat it with his week of preparation?
Each round will have Doom and Vulcan square off in the end, just like in War of Kings where in the end Black Bolt squared off with Vulcan. The only difference is in one round Doctor Doom is not prepared, and in the other Doctor Doom is prepared.
Both Latveria and the Shi'ar Empire can use any and all weapons that it has at it's disposal. That means Doombots, Imperial Guard, etc. Same thing for the battle between Doctor Doom and Vulcan. All of their powers completely at their disposal.
