Another three battle. For all three battles it will be to the death, bloodlust on, no morals, 1v1 with no help what so ever, and at their best.
1. First battle would be Darth Plagueis at the time of his murder, and lets say he didn't get drunk and decided to fall asleep. And lets say Sidious grew a pair, man up, and face Plagueis at that time 1v1.
2. Second battle Darth Plagueis at his prime vs Darth Sidious around the events after the second Death Star was destroyed.
3. Last battle Darth Plagueis around the time of his murder vs Darth Sidious around the events after the Second Death Star was destroyed.
Battle takes place at a Burger King.
