Who would win?
Luffy (Gear Fifth) vs Deku
In Gear Fifth, Luffy's rubber body bends reality like a cartoon, which makes him brutally hard to hurt. Deku hits hard and thinks fast, but his own power wears his body down, and he can't do enough damage to stop Luffy. Luffy can finish Deku; Deku can't finish Luffy.
- Gear Fifth Luffy is very hard to hurt
- Deku wears down faster
- Only Luffy can end the fight
Monkey D. Luffy, captain of the Straw Hat Pirates in One Piece. Gear Fifth is his awakened Sun God Nika form, where his rubber body and the world around him bend like a cartoon.
Izuku Midoriya, the hero of My Hero Academia. Born without powers, he inherited One For All, a stockpiled quirk so strong it can break his own body.
The full breakdown
For the stat fans: every check the engine ran, fighting in character and with no holding back (engine v1.8.21).
In Character
In short
Nothing separates these two on raw power — they stand at the same tier, so scale decides nothing here. Only Luffy can put Deku down. Deku has no route that works here — everything available is either stopped or survivable, so Deku cannot close the fight out. Only Luffy has a valid win condition (a kill, a hold or a shutdown) — Deku cannot end the fight. Luffy wins it clearly.
The tables below show every check behind this, with the numbers the engine used.
Full engine breakdown
Power bracket
| Fighter | Bracket |
|---|---|
| Luffy | 6 |
| Deku | 6 |
Gap of 0. No scoring edge.
Attribute clash
| Axis | Attacker | vs defence | Points |
|---|---|---|---|
| Strength | Luffy (8) | Deku 5 | +15 |
| Strength | Deku (8) | Luffy 5 | +15 |
| Speed | Deku | — speed edge | +6 |
Ability interactions
| Type | Interaction | Points |
|---|---|---|
| counter | Luffy's tactical precognition soft-counters Deku's speed blitz | +8 |
| counter | Deku's spider sense soft-counters Luffy's speed blitz | +8 |
| regen | Luffy heals too fast for Deku to win just by wearing them down | — |
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 | Luffy | Deku |
|---|---|---|
| Kill | PASS reach 5 vs Deku's 0 | FAILED reach 5, needs 7 |
| Contain | FAILED no containment method | FAILED reach 5 — a temporary hold, needs 8 to be permanent |
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 |
|---|---|
| Luffy | YES |
| Deku | 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
| Luffy has no rating for resisting being knocked out or shut down, so it is read from their tier as 3 rather than as none (incap resistance 0 -> 3) |
| Deku has no rating for resisting being knocked out or shut down, so it is read from their tier as 3 rather than as none (incap resistance 0 -> 3) |
| Only Luffy has a valid win condition (a kill, a hold or a shutdown) — Deku cannot end the fight |
Final score
| Key awards | Points |
|---|---|
| Only Luffy has a valid win condition (a kill, a hold or a shutdown) — Deku cannot end the fight | +150 |
The largest awards, not a full ledger — bracket gap, attribute clash and counter points are listed in their own sections above.
Luffy 188 · Deku 34 — margin +154, 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.
