Uni-Power Silver Surfer Vs Thanos
Surfer has become used to fighting his mostly stronger enemies with resourcefulness and cunning instead of raw power). Surfer might even be able to drain more uni-power than he is due.
-=The Uni-Power has not been strictly stated what its limitations are, for this debate, all of Surfer's powers are enhanced 50 fold, matter manipulation, strength, raw power, speed, energy/cosmic awareness, Captain Universe vision, durability, etc, as well as gaining any powers from the Uni-Power he did not previously have before.=-
