Who would win?
Super Sonic vs Goku (Mastered Ultra Instinct)
Super Sonic is ridiculously fast and close to untouchable, but Mastered Ultra Instinct Goku is several tiers more powerful. Sonic's attacks can't do enough to put Goku down, while Goku can hit hard enough to finish Sonic.
- Goku is several tiers stronger
- Sonic can't hurt Goku enough to finish him
- Goku can finish Sonic
Sonic the Hedgehog powered by all seven Chaos Emeralds: golden, flying, faster than ever and almost untouchable, for as long as the emeralds' power lasts.
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.
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
Goku operates on a scale Sonic simply does not compete at. Only Goku can put Sonic down. Sonic has no route that works here — everything available is either stopped or survivable, so Sonic cannot close the fight out. Only Goku has a valid win condition (a kill, a hold or a shutdown) — Sonic 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 |
|---|---|
| Sonic | 7 |
| Goku | 10 |
Gap of 3. Awards 220 points to Goku.
Ability interactions
| Type | Interaction | Points |
|---|---|---|
| regen | Sonic heals too fast for Goku to win just by wearing them down | — |
| invulnerability | Goku out-tiers the attacker; durability gate raised +3 (now 12) | — |
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 | Sonic | Goku |
|---|---|---|
| Kill | FAILED reach 5, needs 8 | PASS reach 7 vs Sonic's 4 |
| 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 |
|---|---|
| Sonic | YES |
| Goku | 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
| Sonic has no rating for resisting being knocked out or shut down, so it is read from their tier as 4 rather than as none (incap resistance 0 -> 4) |
| 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) |
| Only Goku has a valid win condition (a kill, a hold or a shutdown) — Sonic cannot end the fight |
Final score
| Key awards | Points |

Sonic 20 · Goku 370 — margin +350, 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.
