It’s well-established that only people who are “worthy” are able to lift Mjölnir, and there are characters in both the comics and MCU (besides Thor) who have been able to lift it.
But Thor has an extra trick up his sleeve: he can summon Mjölnir if it’s not immediately within reach (for example, if he’s just thrown it at somebody). He reaches out a hand, and Mjölnir comes flying towards him. I've never come across anybody doing this in the MCU, nor the comics.
Has anybody else been able to summon Mjölnir in this way, or is it exclusive to Thor?
