Who would win?
Goku (Mastered Ultra Instinct)vsSung Jin-Woo
Sung Jin-Woo is a real threat: he is fast, tough, heals quickly, and his best plan is to drag the fight out, because Mastered Ultra Instinct drains Goku's stamina. But Goku is two tiers stronger, and nothing the Shadow Monarch has can finish him. Goku can finish Jin-Woo, so he wins.
- Goku is two tiers stronger
- Jin-Woo's best plan is to wear Goku out
- Only Goku can end the fight
Goku from Dragon Ball Super in Mastered Ultra Instinct, the state the angels fight in, where his body dodges and counters on its own without conscious thought.
Sung Jin-Woo, the hero of the Korean web novel and webtoon Solo Leveling. Once the weakest hunter alive, he became the Shadow Monarch, who raises the enemies he defeats as an army of shadow soldiers.
The full breakdown
For the stat fans: every check the engine ran, fighting in character and with no holding back (engine v1.8.18).
In Character
In short
Goku fights at a level Sung Jin-Woo has to reach up to, and the gap shows in every exchange. Only Goku can put Sung Jin-Woo down. Sung Jin-Woo has no route that works here — everything available is either stopped or survivable, so Sung Jin-Woo cannot close the fight out. Only Goku has a valid win condition (a kill, a hold or a shutdown) — Sung Jin-Woo cannot end the fight. Goku wins comfortably — there is no real argument in the other direction.
The tables below show every check behind this, with the numbers the engine used.
Full engine breakdown
Power bracket
| Fighter | Bracket |
|---|---|
| Goku | 10 |
| Sung Jin-Woo | 8 |
Gap of 2. Awards 110 points to Goku.
Ability interactions
| Type | Interaction | Points |
|---|---|---|
| regen | Sung Jin-Woo's regeneration denies Goku a clean win by attrition (survival, not offense) | — |
| invulnerability | Goku out-tiers the attacker; durability gate raised +2 (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 | Goku | Sung Jin-Woo |
|---|---|---|
| Kill | PASS reach 7 vs Sung Jin-Woo's 7 | FAILED reach 7, needs 8 |
| 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 |
|---|---|
| Goku | YES |
| Sung Jin-Woo | 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
| Goku 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 0 -> 7) |
| Sung Jin-Woo has no rating for resisting being knocked out or shut down, so it is read from their tier as 5 rather than as none (incap resistance 0 -> 5) |
| Only Goku has a valid win condition (a kill, a hold or a shutdown) — Sung Jin-Woo cannot end the fight |
Final score
| Key awards | Points |
|---|---|
| Only Goku has a valid win condition (a kill, a hold or a shutdown) — Sung Jin-Woo 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.
Goku 270 · Sung Jin-Woo 40 — margin +230, graded decisive. 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.
