Tank doesnt mean escape or evade, it means to literally tank it. Take the force head on and survive. If tanking meant escaping then Goku could easily do that too. And btw I'm taking Thir's side on this. Goku's only advantage is fighting skill and overall better speed (maybe). Thor takes it in strength, durability, stamina, and hax.
Also speed isn't a problem for Thor, seeing how he evaded Silver Surfer in one of their encounter's. He has reaction speed, just not travel speed.
No he really doesn't. The Silver Surfer doesn't have that good combat feats either. He got tagged by the Thing so trying to use him as a basis for Thor's combat speed isn't very good at all. Have a look at this link and you'll see why Thor's combat speed is pretty poor. It includes feats and arguments from the Vine's best debaters and is one of the best sources of Thor's true combat speed. This is why Goku can give him some trouble IMO: http://www.comicvine.com/forums/battles/7/thor-runs-the-combat-speed-gautlet/691255/?
Most of the times Silver Surfer gets tagged by guys like thing it's simply PIS, to make the plot more readable. SS is widely known as the fastest being in Marvel, or maybe any comic, so to say SS feats have no use is just plain stupid.
@Petey_is_Spidey: Physical or energy projection ones? And there is the whole Ki control point to consider. According to the more reasonable DBZ experts I trust on here, Goku and the other characters can concentrate their energy into a blast that is much smaller but still packs the same punch.
His physical attacks will do absolutely no damage. His Ki ones could do some, but even if the blast is small, it still takes a while to finalize. Not as long as the people on this sight think, though.
Well each character has their own distinct merits in the fight.
Greater physical strength
Better striking power with Mjolnir
Longer lasting stamina
Mjolnir can absorb and redirect Goku's energy blasts
Faster combat speed so can dodge Thor's lightning
Faster reaction times
Instant Transmission can avoid Thor's redirected blasts
More versatile energy manipulation projection attacks
Better hand to hand feats
All in all, although this would be easier for Goku to win if the version was from the Majiin Buu saga or included GT feats, Cell Games Saga Goku should be fast enough to pull off a win. Thor's combat speed and reaction times are laughable and although Mjolnir can redirect Goku's attacks, meaning that if Goku wasted enough energy, Thor could deliver a finishing blow to a weakened Goku, there's no reason why Goku can't pull off an IT Kamehameha or speed blitz Thor into the ground. There is a chance Thor can win but it's more likely that Goku can manage to wear Thor down.
Goku's attacks aren't enough to put down Thor, and the ones that are would take a while to charge up.
Goku, personally is the weak link. Not physically up too par with the other two. His energy alone can't take out those two heavy hitters. Thor is equal to Superman in strength and durability, though Superman is much faster and quicker. What gives Thor the edge is his magic, energy projection, and Mjolnir. A full strength Thor is on par with Odin, which Superman can't stand a chance against.
