The most powerful version of each.
Selene & Alice
Yoda & Darth Sidious
Alice has TK and all her weapons.
Selene has already drank Corvinus' blood, and has all her weapons.
Yoda is in his prime. And Sidious at his most evil. They have light sabers, force, dark side.
They all start 300m apart inside a God proof dome with huge boulders strewn about, which can be used for cover.
Fight to the death.
