Higher arguments for attack potency with dimensional tiering
Able to resist or resist the majority of Goku and Vegeta’s abilities, including power null, time manipulation, existence erasure, general status effects, etc, with All Recover being able to undo any effects that do actually work
All Delete works on a much larger, thorougher, and more destructive scale than Hakai, making it unlikely Goku and Vegeta can resist it
Omega inForce precog is likely superior to Ultra Instinct, is less strenuous to use, and can even function against causality manipulation
Abilities like Character Reversal negates any resistances Goku and Vegeta have to his attacks
Fusion methods are easier to utilize and maintain
Omnimon’s digital body can withstand hits or injuries that would normally be fatal for an organic being, allowing him to keep fighting even while injured
Badass cape
Defeated racism
Superior in fighting skill with better training
Generally has a larger amount of unique skills and abilities
With equips like Infinite Energy Reactor, plenty of stamina recovering card abilities, stamina recovery capsules, as well as very impressive stamina feats in general, could potentially be able to outlast Omnimon
Summoning characters via cards gives a numbers advantage
Using the Key Sword to rewind themselves through time can both remove the issue of their Fusion timer and undo any negative status effects…
Able to resist the majority of Omnimon’s hax…
Badass vest
GO-GETA, GO-GETA, GO-GETA, GO-GETA, GO-GETA, GO-GETA, GO-GETA, GO-GETA
…but rewinding time in such a manner is something they have never done
Much weaker with dimensional tiering
Omnimon resists a majority of Goku and Vegeta’s abilities
All Recover nullifies any status affects Goku and Vegeta can inflict
Likely can’t survive All Delete, as it works on a much larger, thorougher, and more destructive scale than Hakai
…however, moves like Character Reversal also negate resistances all together, likely making them susceptible to All Delete, absolute zero, and so on
Ultra Instinct is likely worse than Omega inForce in terms of precognition
Fusion methods are normally more difficult to both achieve and maintain
Next official episode is literally having them kill themselves
