Characters Who Are Most Worthy Of Lifting Mjolnir

Not just anyone can lift Thor's hammer. Thanks to an enchantment by Odin, only one who is worthy can wield it. While worthiness is rather subjective, it's no joke. Many physically strong beings have tried to heft it, but can't even get it to budge.

In the comics, there are a number of characters who have lifted Mjolnir. Some of them are in the main Marvel continuity. Some are from alternate continuities, what-ifs, or company crossovers. Based on what we know about Thor as a character in the comics, who do you think should be able to lift Mjolnir with no problem?
