Flawless logic

For whatever reason, I thought that you were going to say Jane Goodall

That doesn't make any fucking sense, Thor is his name not a title. Why would someone else who's worthy of the hammer have their name changed to Thor?

Because she knows him, and when she takes up Mjolnir she transforms from sickly, dying, cancer patient Jane Foster into the Valkerie-esqe Thor you see above. She chooses to take it on as a title.

Jesus Christ.
This is why I don't read cape-shit.

You've got Loki, a shapeshifter. Technically counts.

We have Bucky Barnes, the best princess.
