If Cell had absorbed a Mouma from Dragon Ball GT, he could have achieved his 'perfect' form. Mouma are enormous, man-eating worms with incredibly tough shells on their heads, resistant even to the attacks of Goku and his allies. Absorbing a Mouma would have fortified Cell's most vulnerable spot, rendering him unbeatable.
Cell, a formidable antagonist in the Dragon Ball universe, becomes even more formidable in Dragon Ball GT, unveiling a path to further augment his strength. In the original Dragon Ball Z saga, Cell proved exceedingly resilient, capable of regenerating from virtually any injury inflicted by Goku and the Z-Fighters. Despite his robustness, his potential for invincibility lay untapped until Dragon Ball GT introduced an upgrade that could have perfected his form.
As a bio-android created by Dr. Gero, Cell amalgamated the greatest abilities of both villains and heroes from Dragon Ball lore up to that point. Notably, his regenerative capabilities, inherited in part from Piccolo, rendered him nearly indestructible. However, this trait came with a vulnerability, one that could have been remedied by a life form introduced in Dragon Ball GT.
In Season 1, Episode 10 of Dragon Ball GT, Pan, Goku, and Trunks find themselves stranded on an asteroid, contending not only with isolation but also with the formidable Mouma inhabitants. These giant, shell-covered worms possessed such impenetrable defenses that even the combined might of Goku, Trunks, and Pan failed to subdue them. Had Cell absorbed a Mouma, his weakest spot—revealed in the Cell Saga—could have been reinforced, potentially rendering him impervious to fatal blows.
While Cell required the absorption of Androids 17 and 18 to achieve significant transformations, his ability to assimilate traits and powers from others remained a potent capability. Had he been aware of the Mouma during the events of Dragon Ball GT, Cell could have ensured his invincibility by reinforcing his vulnerable cranial area, as demonstrated in the episode.
Dragon Ball GT, the third series in Akira Toriyama's iconic anime franchise, departed from manga adaptations but continued the saga following the Buu Saga. Despite receiving mixed reception upon its original airing, Dragon Ball GT remains a significant part of the series' legacy, showcasing Goku and the Z-Warriors battling formidable adversaries like Baby, Super 17, and the Shadow Dragons.
For fans, all episodes of Dragon Ball GT are available for streaming on Crunchyroll, offering a deep dive into the enduring world of Dragon Ball.
