Who would win?
Base Batman vs Spider-Man
Without prep time, this is a peak human against someone with real superpowers. Spider-Man is stronger, faster and tougher, and his spider-sense warns him before Batman can strike from the shadows. Both of them can take the other down, but Spider-Man is harder to hurt, so he finishes it first.
- Spider-Man is stronger, faster and tougher
- Spider-sense beats Batman's stealth
- Both can win; Spider-Man lasts longer
Bruce Wayne from DC Comics: a peak-human detective and martial artist who fights crime in Gotham with gadgets, planning and sheer will. This is Batman with no prep time.
Peter Parker from Marvel Comics. Bitten by a radioactive spider, he has spider-like strength and agility, sticks to walls, swings on web-shooters he built himself, and has a spider-sense that warns him of danger.
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
Spider-Man has the edge in raw power, but only just — one tier is an advantage, not an answer. Both fighters have a way to end the fight, so it comes down to who lands it first. Both can finish, so it turns on who survives the exchange — Spider-Man is harder to put down than Batman, so is favoured to land the finish first. Spider-Man wins it clearly.
The tables below show every check behind this, with the numbers the engine used.
Full engine breakdown
Power bracket
| Fighter | Bracket |
|---|---|
| Batman | 1 |
| Spider-Man | 2 |
Gap of 1. Awards 45 points to Spider-Man.
Attribute clash
| Axis | Attacker | vs defence | Points |
|---|---|---|---|
| Intelligence | Batman (8) | Spider-Man 2 (UNDEFENDED x1.5) | +53 |
| Skill | Spider-Man (6) | Batman 1 | +25 |
| Speed | Spider-Man | — speed edge | +9 |
Ability interactions
| Type | Interaction | Points |
|---|---|---|
| counter | Batman's tactical precognition soft-counters Spider-Man's speed blitz | +8 |
| counter | Spider-Man's spider sense soft-counters Batman's tactical stealth | +8 |
| speed | Spider-Man is far faster (speed 6 vs 3) -> evasion + initiative (+20, survival not a kill) | — |
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 | Batman | Spider-Man |
|---|---|---|
| Kill | PASS reach 5 vs Spider-Man's 3 | PASS reach 5 vs Batman's 0 |
| 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 |
|---|---|
| Batman | YES |
| Spider-Man | YES |
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
| Both fighters have a valid win condition — scale decides who lands it first |
| Both can finish, so it turns on who survives the exchange — Spider-Man is harder to put down than Batman, so is favoured to land the finish first |
Final score
| Key awards | Points |
|---|---|
| Both can finish, so it turns on who survives the exchange — Spider-Man is harder to put down than Batman, so is favoured to land the finish first | +24 |
The largest awards, not a full ledger — bracket gap, attribute clash and counter points are listed in their own sections above.
Batman 27 · Spider-Man 137 — margin +110, graded clear. Points accumulate from the checks above. The engine resolves the fight; the AI only narrates the result it reached.
No Holding Back
In short
Morals make no difference to this one — it resolves exactly as above.
