I really don't see how this is a fair fight in anyway.
Just look at their profiles, and you will see how badly Lupin outclass White by having simply all the advantages from durability, speed (even if its equalized), strength, versatility, weaponry, equipment, hax, stamina, intelligence, experience and skills.
Even with preparation time Lupin still easily win if not stomp, with his higher intellect and far more OP gadgets, White simply cannot win.
