Stormbreaker, unlike its predecessor Mjolnir, is less challenging to wield, making it accessible to several MCU characters.
Thor, as the God of Thunder and son of Odin, possesses immense strength and the ability to generate electrical energy. Initially, he relies on Mjolnir to focus his power and deliver significant blows.
However, Thor is not the only character to have handled Mjolnir; his sister Hela also used it before him. In Thor: Ragnarok, Hela destroys Mjolnir, forcing Thor to learn control over his powers without the hammer to defeat her.
