Agreed.
Mace vs Riku...
Round One...
Lightsaber vs Keyblade
Lightsaber can easily cut through the keyblade, and any flesh. Riku's keyblade is NOT indesructable and doesn't kill people instantly like the lightsaber.
Mace wins.
Round Two...
The Force vs Darkness
Mace can use the force to push Riku and trip him and all sorts of stuff.
ALSO, VAAPAD USES THE OPPONENT'S DARKNESS AGAINST THEM. Thus, Riku slowly has his darkness attack him inch by inch, and he dies eventually, even if he can out-last Mace Windu.
All Riku can do is summon dark firaga which Mace can easily block.
Mace wins.
Round Three...
Strong man vs skinny teenager
Face it, Mace can do a lot more manuevers than Riku, and he's a lot stronger.
Mace wins.
The winna... MACE WINDU!!!
Riku loses.
