Which was the comic book where Captain America became worthy to hold Mjolnir ?
This happens in:
- The Mighty Thor #390 (1988)
During a period where Steve had abandoned the mantle of Captain America and gone independent as "The Captain." Cap paid a visit to his buddy Thor at Avengers Mansion, only for the team to be attacked by Grog and the Demons of Death (great band name). When Thor was subdued by the combined might of these villains, Cap was able to lift Mjolnir long enough to send it back to its rightful owner.
- Fear Itself #7 (2011)
Cap had the chance to wield Mjolnir for a slightly longer stretch in the event Fear Itself. With his trusty shield having been shattered by the Serpent, Cap had nothing but some automatic weapons to battle the Serpent's minions. Luckily for him, Thor lost his grip on Mjolnir during his battle with his uncle. Mjolnir crashed to Earth, and Cap hoisted it high and led the charge.
