Thanos's superior durability, energy projection, and cosmic-level power give him the edge over the Viltrumite.
Both are incredibly powerful warriors with ruthless combat philosophies. Omni-Man has FTL speed and planet-cracking strength, while Thanos has traded blows with the Hulk and survived attacks from cosmic entities. The matchup is closer than many expect.
Omni-Man's speed advantage is significant โ he can deliver devastating combinations before Thanos fully responds. But Thanos's durability is on another level entirely. He has withstood attacks from beings far more powerful than Omni-Man and kept fighting. The Viltrumite's punches would hurt but not decisively damage the Titan.
Thanos's energy projection and cosmic awareness give him options Omni-Man lacks. He can fire energy blasts powerful enough to stagger Galactus's heralds, and his tactical genius is comparable to the greatest minds in Marvel. Once Thanos adapts to Omni-Man's speed, his counter-attacks would be devastating.
Omni-Man's FTL speed gives him first-strike advantage and his planet-cracking strength is formidable. His thousands of years of conquest experience mean he is tactically ruthless and never hesitates.
Thanos has survived attacks from cosmic entities and his durability exceeds Omni-Man's offensive output. His energy projection, cosmic awareness, and superior intellect give him tools to counter Viltrumite speed.
Thanos wins through superior durability and cosmic-level power. Omni-Man's speed makes this competitive, but Thanos has tanked attacks from beings far stronger and can counter with devastating energy blasts.
