Mjolnir vs. Mjolnir
Pretty simple question. If you are worthy and pick up regular 616 Thor's Mjolnir in the current timeline you get his powers, correct?
What if you pick up Old King Thors Mjolnir in the future? Do you Old King Thors stats? Or if you picked up a younger Thor's mjolnir, like when he first became worthy? Would you be weaker than current Thor? Since he gets stronger with age.
If 3 different versions of you carried 3 different copies of Mjolnir from across the timeline and then fought would there be a difference?
And if a young Thor were to grab Old King Thors hammer would he become that strong?
