SSJVegeta
V, from the film V For Vendetta
VS
Rinzler, from the film Tron: Legacy
They are both armed with their standard weapons, Rinzler has his two Identity Discs and V has two of his knives, and they are, as you can see above, already fighting. They are fighting in the Arena, so there will be no outside interference, and if Rinzler finds out and then questions the fact that V is technically a User he will be told to kill him anyway. V's knives work the same way Identity Discs do, as weapons, in this scenario.
