Doctor Watson No-Damage Guide
Last reviewed: · Sources & evidence status below
Quick answer: defeat Doctor Watson (Watson Industries) without taking any damage to unlock Inevitably Stupid and receive the Ame's Hat. A hit does not fail the fight — it only fails the reward — so the moment you are clipped: pause, Retry Boss, restart the attempt.
Doctor Watson is the final boss of Watson Industries, and the only four-phase fight in the game. The phase list is community-sourced; per-phase timings and attack data are pending capture.
The four phases (community-sourced)
- Robot form — the opening mechanical body.
- Saucer blade / UFO "beyblade" phase — the mobility phase.
- Human Watson — the syringe-throwing phase.
- Final phase — after the syringe injections, the last stretch of the fight.
The phase-isolation method
Treat the fight as four separate no-damage minigames, not one long run. If you get hit in phase 2, pause and use Retry Boss — use the attempts to drill the exact phase that is beating you. When each phase is individually clean, chain them: the achievement and Ame's Hat check only the final clean pass. Save this fight for last among the five — patterns drilled on the earlier bosses carry over.
Rewards
| Reward | Condition |
|---|---|
| Inevitably Stupid (achievement) | Win without taking damage |
| Ame's Hat | Same clean win — drops from the boss |
The no-damage workflow
- Save manually before engaging (Save Anytime).
- Fight once casually to read the attack patterns — a death here costs nothing.
- On the clean attempt, pause → Retry Boss the instant you take a hit. Never finish a spoiled run.
Community consensus: the hardest no-damage fight in the game — both guides call it the last hill of the 100% climb.
