Who would win?
Base Superman vs Omni-Man
Omni-Man is one of the most brutal fighters in his universe, but Superman is several tiers above him. Omni-Man's hardest punches can't do real damage to a body that tough, so he has no way to end the fight. Superman can end it, and does.
- Superman is several tiers stronger
- Omni-Man can't do real damage to Superman
- Only Superman can end the fight
Kal-El from DC Comics: the last son of Krypton, raised in Kansas, who draws his strength, speed, flight and heat vision from Earth's yellow sun.
Nolan Grayson, Invincible's father, from Robert Kirkman's Invincible. A Viltrumite warrior sent to conquer Earth who posed as its greatest hero.
The full breakdown
For the stat fans: every check the engine ran, fighting in character and with no holding back (engine v1.8.19).
In Character
In short
Superman exists on an entirely different order to Omni-Man — this is not a fight so much as a demonstration. Only Superman can put Omni-Man down. Omni-Man has no route that works here — everything available is either stopped or survivable, so Omni-Man cannot close the fight out. Only Superman has a valid win condition (a kill, a hold or a shutdown) — Omni-Man cannot end the fight. Superman obliterates the matchup. It is not close and it was never going to be.
The tables below show every check behind this, with the numbers the engine used.
Full engine breakdown
Power bracket
| Fighter | Bracket |
|---|---|
| Superman | 10 |
| Omni-Man | 6 |
Gap of 4. Awards 380 points to Superman.
Ability interactions
| Type | Interaction | Points |
|---|---|---|
| speed | Superman's speed hasn't been rated, so neither side gets a speed edge | — |
| invulnerability | Superman out-tiers the attacker; durability gate raised +3 (now 11) | — |
Soft counter: reduces an ability's effectiveness without nullifying it. Hard counter: the ability does not function against this opponent at all.
Win conditions tested
| Check | Superman | Omni-Man |
|---|---|---|
| Kill | PASS reach 7 vs Omni-Man's 0 | FAILED no finishing attack |
| Contain | FAILED no containment method | FAILED no containment method |
A kill lands only when the attacker's reach meets or beats the defender's resistance. Containment must clear two bars: it has to out-reach the opponent's escape and reach 8 to hold permanently — below that it is a temporary hold that lapses. A fighter who fails both cannot end the fight, however much damage they do — which is how an outmatched fighter can still force a stalemate.
Can they threaten at all?
| Fighter | Has a usable offensive route |
|---|---|
| Superman | YES |
| Omni-Man | NO |
This checks only whether a fighter can meaningfully attack at all. It is tested before the win conditions above — so a fighter can pass here and still have no way to finish the opponent.
Rulings
| Superman is rated at 5 for resisting seals, prisons and banishment (escape 0 -> 5) |
| Superman has no rating for resisting being knocked out or shut down, so it is read from their tier as 7 rather than as none (incap resistance 6 -> 7) |
| Omni-Man has no rating for resisting seals, prisons and banishment, so it is read from their tier as 3 rather than as none (escape 0 -> 3) |
| Only Superman has a valid win condition (a kill, a hold or a shutdown) — Omni-Man cannot end the fight |
Final score
| Key awards | Points |

No Holding Back
In short
Morals make no difference to this one — it resolves exactly as above.
