DOS DD would beat Thor 10/10 in less than 3 sec.
Here's why:
Thor has been hit by slower moving enemies a billions times.
Thus he will get hit by DD several times in less than .0001 of a sec, ending the fight with Thor either dead or unconscience and half dead.
Superman's physical durability>>>>Thor's physical durability
Doomsday would literally tear a gapping hole thru Thor's head with those bony protrusions.
HP DD would beat Thor 1000000/10 in less than .000000001 sec.
Same as before only that this DD is completely immune to all things except the End of Time and the virus that undoes his DNA. Look at what happened to Darkseid and Darkseid>>>>>>Thor. Look at what happened to Superman. His protrusions went through Superman's body like tissue paper (even before Superman can react). Just imagine what he will do to Thor. He can evolve in battle and is immune to all (oops! I said that already)
In both above scenarios there would be no time for any teleporting tactics. DD will be on Thor like white on rice (killing Thor almost instantly).
In RKT vs. Gog DD it all depends on prep. If RKT has any prep then he wins. This is because he can teleport him (before DD strikes) to the End of Time. If he has no prep and sees DD for the first time (right before DD strikes) then DD wins 10/10. This is because RKT is the same as Thor (Same strength, durability, reaction time, and skill [unless he upgrades himself through use of his power]) but with great magic power.
And the fact that he won't have time to upgrade himself. For Gog DD will be on him like white on rice. Those bony protrusions will be stuck in Thor's head (killing him instantly).
