|Alias||Galacti, Gah Lak Tus|
|First appearance||"Fantastic Four #20"|
Galan was a peasant on the alien planet of Ta. Both of his parents and brothers were dead and he was close to death himself. However, one day, the universe exploded, birthing an all new one. Galan alone survived the blast and was transformed into Galactus.
After Galactus had begun consuming planets, he reached Maklu-IV. He was going to consume it, but a man named Norrin Radd struck a bargain. He would become Galactus's herald if he frees Maklu-IV. Galactus accepts and transforms Norrin into the Silver Surfer.
Galactus once reached Skrullos, the home planet of the Skrulls. He was activating the ancient Skrull prophecies by consuming the planet. However, most of the Skrulls managed to avoid his wrath by blasting off into space.
When Galactus came to Earth, Silver Surfer was convinced by the Invisible Woman that destroying Earth was a bad idea. He betrayed Galactus and helped battle him, though it did not matter. However, Reed Richards was able to get a hold of the Ultimate Nullifier. He had complete concentration when he used it on Galactus, and he was destroyed.
