History: Galactus is the sole survivor of the universe that existed prior to the creation of the current universe. Originally Galactus was a humanoid named Galan, who was born on the planet Taa, a paradise-like world whose civilization is said to have been the most advanced of any of the known universe of that time.
However, this universe was in its final stages of collapse. Originally, this universe had been a "Cosmic Egg," a primal sphere of disorganized, dense, compact primordial matter. The sphere underwent a "Big Bang," an explosion that hurled the matter outwards, where much of it eventually condensed into stars and planets. This universe expanded in size for billions of years, and then contracted over the following billions of years. All of the matter of that universe was plunging towards a central point, where it was collapsing into a new "Cosmic Egg."
Taa's civilization was one of the last still in existence. Lethal radiation caused by the death of this universe was wiping out life on nearby planets. Galan, a space explorer, was dispatched to travel through the cosmos to find a means of saving Taa, but he found none. The radiation then killed off all but a tiny fraction of the population of Taa. Knowing their deaths were inevitable, Galan proposed to the remaining survivors that they die gloriously by traveling in a starship straight into the "Cosmic Egg." As the starship approached its destination, radiation killed all the passengers except Galan, who strangely found himself filled with new energy.
The sentience of the dying universe, contained within the "Cosmic Egg," prevented Galen and his starship from being destroyed by the "Egg's" tremendous gravitational forces and heat. (Presumably, this was a previous incarnation of Eternity, the embodiment of the life forces of the current universe.) The dying universe's sentience contacted Galan, telling him that they both would die, but that both would be reborn, and that Galan would thus become Galactus, ravager of worlds. The "Cosmic Egg" absorbed Galan into itself.
There is no way of determining how much time passed between the death of that universe and the creation of the current one. But finally the "Cosmic Egg" underwent another "Big Bang," thus creating the current universe. Eternity and Death, the ethereal embodiments of the new universe, were created in this "Big Bang," and the being that had been Galan was simultaneously hurled outward in his recreated starship. (It is because all three were created simultaneously that Galactus refers to Eternity and Death as his siblings.)
The nascent Galactus drifted in his starship for eons as life began to come into existence in the universe, including the races that would give rise to the Elders of the Universe. Eventually the nascent Galactus's starship was sighted by one of the Watchers, an ancient race of beings who had undertaken to observe the events of the universe. This Watcher, who was not Uatu, the Watcher who observes Earth, drew the starship down to his planet to study it. There he learned that the being within it had vast, growing power, and would eventually have to consume worlds to satiate his hunger for energy. Realizing the danger the nascent Galactus posed to the cosmos, this Watcher considered destroying the being before he harnessed his full power, but instead decided to abide by the Watchers' oath of non-interference, and let the nascent Galactus depart in his starship.
The nascent Galactus learned how to use his vast power, and created a suit of armor to help him regulate it. He then transformed the starship into a kind of incubation chamber, where Galactus spent centuries evolving into his current form. Finally, the incubation ship drifted into orbit around the inhabited planet Archeopia. The Archeopians themselves did not disturb the strange ship, but years later a marauding space fleet, nearing Archeopia and thinking Galactus's ship to be a weapon, attacked it. Galactus, his incubation finished, emerged, destroyed the fleet, and then, hungering for energy, consumed the biospheric energy of Archeopia. A small fleet of Archeopian ships managed to escape, but all life on the planet was destroyed. (The Archeopian race would later be fully exterminated by the living planet Ego).
Over the following millennia Galactus built himself an immense starbase, the world-ship he calls Taa II, which engulfs the Archeopian solar system. Galactus also sought out planets rich in certain unknown energies that he consumed to sustain his life. During these many millennia Galactus consumed only planets uninhabited by sentient lifeforms, except for Archeopia, and many centuries passed between his "feedings.''
However, as ages passed, the intervals between feedings decreased considerably in length, and Galactus found himself needing to consume worlds inhabited by sentient races if he could find no other worlds possessing the energy he needs in time to sustain himself. Galactus has succeeded in suppressing his sympathy for intelligent beings like himself when he was Galan, and, believing himself to be a higher kind of being than they, is willing to destroy their lives to continue his own. Moreover, he is aware that he was created to fulfill an as yet unrevealed purpose that he believes will ultimately compensate the universe for all the destruction he wreaks.
At one point Galactus threatened to destroy the planet Zenn-La, home of a civilized race. One of that world's inhabitants, Norrin Radd, persuaded Galactus to spare the planet by volunteering to become his "herald" and search out uninhabited worlds for him to consume. Galactus agreed, and transformed Norrin Radd into the Silver Surfer.
Eventually, however, Galactus grew determined to consume the energy-rich planet Earth. The Surfer rebelled as a result, and Reed Richards of the Fantastic Four thwarted Galactus by threatening to use an alien device called the Ultimate Nullifier on him, a weapon that could kill even Galactus. Galactus was forced to vow to spare Earth, and he punished the Surfer by erecting an energy barrier that prevented the Surfer from leaving Earth.
Despite his pledge to Richards, Galactus returned several times to Earth to consume it, but was always narrowly thwarted. Meanwhile, he consumed numerous inhabited worlds throughout the known universe to sate his hunger, and was feared as a menace to all known star faring races. Galactus also took on a succession of new heralds.
During his last attempt to destroy Earth, Galactus had gone so long without "feeding'' that his energies were severely waning, and a large number of Earth's superhuman defenders actually succeeded in defeating him in battle. Galactus lay dying from lack of energy, but Reed Richards saved his life. The grateful Galactus pledged his friendship to Richards and sincerely gave his word never to attack Earth again. Galactus has steadfastly abided by this oath ever since. During this visit to Earth Galactus recruited his latest herald, Nova.
Galactus continues to prey upon other worlds, and recently he destroyed the Skrull throneworld, thereby plunging the Skrull Empire into chaos. There is an account of a far distant alternate future, in which man no longer exists on Earth, and Galactus, therefore no longer feeling bound by his oath, consumes it at last.
At some point afterward, Galactus was targeted by the alien organization Elders of the Universe, who believed his death would trigger a Big Bang and recreate reality. His former herald, Silver Surfer, saved him.
Galactus was believed to have developed romantic feelings for his herald Nova. When Nova finally rebelled as his herald, Galactus created another in the alien Morg, who ultimately murdered Nova on his own volition. Morg in turn was defeated by the collection of his heralds, leaving Galactus alone again.
More recently, Galactus' appetite became such that he would only eat on planets of sentient life. He began to consume more and more frequently, developing a mania. He created a new herald, Red Shift, to help him succeed in this. He approached Earth once more, and had to be driven off by a large contingent of Earth's superheroes, and Red Shift was defeated. Finally, he was repulsed by the Silver Surfer, who agreed once more to become Galactus' herald and to search for planets, this time of sentient life to consume. Almost immediately, the Silver Surfer led Galactus to the homeworld of the Shi'ar Empire, perhaps the most

So, basically, if Batman had to train a bunch of clueless people to beat Galactus in exactly 23.657 minutes, could he do it?No.
DONT EVERTHINK SO LOW OF THE BATGOD..................... even without powers he can rip throu the multiverse with his hands alone. given him ten sec of prep is like give giving him an infinit hours of prep
