10 Most Powerful Characters Killed By Thor

Thor may be extraordinarily powerful, but Galactus is leagues beyond him in every way. Empowered by the Power Cosmic, the primordial being feasts on entire worlds to sustain him and has gone up against multiple legions of heroes, with the heroes barely prevailing during each encounter.

This made his death at the hands of Thor all that more shocking, even if one took into account that the Asgardian was boosted by the Black Winter, a mysterious being who had destroyed multiple universes in the distant past. Shockingly, Galactus had been the Black Winter's Herald, much in the same way the Silver Surfer was his.

Initially, Thor and Galactus formed an alliance to stop the impending Black Winter, but their vastly different approaches often put them at odds. When the overpowered duo finally confront their opponent, the Black Winter reveals that Thor is fated to kill Galactus.

Naturally, Thor took the opportunity to strip his one-time ally of the power he had recently consumed, and used it to destroy both cosmic entities.
