The Fortress of Solitude Vs Thor, Dr. Strange, Hulk

Can the fortress resist the efforts of any of the below characters to breach its defenses?

The characters have no prep.
Superman (and Krypto) are not there.
This isnt some sort of gauntlet, each is a stand alone attempt.

I believe all of them can penetrate the FoS. None will do it by picking the key and opening the door the way Superman does it, but all should be able to enter in their own ways. Many ways to skin a cat.

A streaky supercat, even!
