He and his crew evolveinto the planet’s most formidable zombies,erasing a vast share of the human race with an insatiable appetite and sealing their place as one of the most dominant versions of the super-hero ever conceived.

With a cataclysmic war threatening the multiverse itself, Uatu makes the drastic choice to grant Reed Richards the Watchers’ boundless abilities to save all reality, and the brilliant scientist instantly becomes an omniscient entity capable of perceiving every timeline at once.
His knowledge grows so immeasurable that he drifts completely from any human feeling, turning into a purely logical, objective presence able to impose ruthless decisionsonce he calculates outcomes for the multiverseas a single system. Even after relinquishing that power by the story’s end, the memory of having been a higher entity leaves Reed profoundly shaken, forever aware of what he once became.
4Doom (Timeless)
This Is One Of The Hero’s Most Powerful Versions When Mastering Reality

Feared even by Kang, this version of Reed Richards in Marvel comics stands as a linchpin in the temporal war, mastering both time and reality without succumbing to corruption, an achievement that starkly contrasts with the feared conqueror’s darker ambitions.
Reed not only possesses the knowledge Kang craves but also wins the race to comprehend the universe, all while retaining certain values and traits intact in one of his most potent comic incarnations. Armed with rare Celestial bloodand the potent Time and Reality Stones,he nonetheless remains susceptible to catastrophic physical wounds, a frailty brutally demonstrated when Dr. Anatoly Petrov suddenly impaled him on jagged metal.
3Alpha (Fantastic Four)
This Version Of The Hero Becomes Dangerous Through Its Lack Of Humanity
Willing to embrace questionable measures for the multiverse’s greater good, Alpha stands among the most formidable versions of Mister Fantastic in Marvel comics.

By wielding a fragment of Celestial power alongside the Infinity Gauntlet, he amplifies his abilities to near-divine levels and grows truly perilous, surrendering to an uncompromising idealistic vision. Convinced he alone can repair everything, this iteration of Mister Fantastic so shocks the real Reed Richards of Earth-616, who still cherishes his family bonds, that their encounter underscores how far unchecked intellect can stray from humanity.
2The Maker (Ultimate Fantastic Four)
Driven By Trauma And Disdain, He Is The Hero’s Darkest Version
Debuting as a hero inUltimate Fantastic Four, Mister Fantastic ultimately reaches the terrifying zenith of his power by becoming one of Marvel comics’ greatest and most feared villains to date. Still brilliant and the team’s founder, he begins to cultivate a warped view of humanity after enduring multiple traumas, including his breakup with Sue Storm and the destruction of his family.
Consequently, he matches the genius of Earth-616’s Reed Richards yet lacks any moral restraints, adoptingoutright genocidal behavior during his campaignsand executing entire populations without hesitation. Aiming for intangibility, the villain rebuilds his body through genetic engineering until killing him is almost impossible, and when his universe collapses he still breaks through to Earth-616, a testament to his colossal power.
1Reed Richards (Secret Wars)

As the multiverse collapses into catastrophic incursions, the hero steps forward in what is unequivocally his most powerful incarnation of Mister Fantastic ever chronicled within Marvel comics. At the story’s climax he confronts Doctor Doom, yet Molecule Man,the villain’s true power source,transfers that cosmic might to the leader of theFantastic Fourupon realizing Reed would govern reality more wisely.
Endowed with the Beyonders’ power, Mister Fantastic becomes outright omnipotent, wielding the faculty to recreate the multiverse and exert total autocratic control over reality, space, and time across every dimension. He thereby attains godhood, patiently rebuilding the realities Doctor Doom shattered and, across the rebuilt cosmos, the fandom fittingly refers to this transcendent figure as God Reed or Reed-Beyonder.
