Mandarin vs Midnighter
In this scenario the Midnighter is infiltrating the Mandarin's stronghold. Midnighter enters the castle, and sees that the Mandarin has removed his rings, which gives him the perfect opportunity to strike. Just as Midnighter crashes through the window, the Mandarin sees him, and braces for the attack. He does not have enough time to put the rings on, as Midnighter charges, and carries him through a wall, while simultaneously tossing a concussion grenade that brings the ceiling down burying the rings. They topple over a banister in the main hall of the castle. The fight begins.
