Well, it varies depending on the comic series. Sometimes, it's been a combined effort of multiple superheroes like the Fantastic Four and others. Each encounter has its own unique circumstances and outcomes.
Galactus' fate in the comics is complex. It's not straightforward to say who exactly killed him as it often involves multiple factors and characters coming into play. Different storylines present different scenarios.
Strange was able to defeat Dormammu in the comic by manipulating time with the Time Stone. He made it so that the same events kept repeating, which eventually wore down Dormammu's patience and forced him to back off. Strange's knowledge of magic and his willingness to take bold risks were key factors in this win.
The covers of Galactus comics usually showcase his unique costume and helmet, along with a backdrop of the universe to emphasize his cosmic nature. They might also highlight his interaction with other powerful characters.
There's a 'galactus crossover fanfiction' that involves Galactus and the Doctor from 'Doctor Who'. This one is really cool as it takes the concept of Galactus' destruction and the Doctor's ability to time - travel and save planets. The story has some really creative plot twists. For example, the Doctor tries to find a way to satiate Galactus' hunger without sacrificing entire planets. It's a unique blend of two very different fictional universes.
Galactus was once a mortal named Galan in the pre - Big Bang universe of Taa. As the universe was about to end in a cataclysm, Galan entered a life - pod with some other survivors. But the pod entered a radiation - filled area near the Big Bang. Galan was transformed by this intense energy and became Galactus, a being with an insatiable hunger for planets to sustain his vast power.
Well, Doctor Strange outsmarts Dormammu in the comic. He uses his knowledge of the multiverse and time manipulation to create an endless cycle that Dormammu can't escape from. Eventually, Dormammu gets so frustrated that he agrees to Doctor Strange's terms and backs off.
