Bottle Cap & Hyper Training Guide
Hyper Training pushes a Pokémon's IVs up to 15. Two cap types exist — Gold (all 3 stats) and Silver (one stat) — with different eligibility and value.
Gold Bottle Cap vs Silver Bottle Cap
Both items start "Hyper Training", but they differ in how many stats they can boost.
Gold Bottle Cap
All 3 stats
- •Can raise Attack, Defense, and HP — all up to 15
- •Debuted June 2025 via GO Pass Deluxe "Echoes of the Past"
- •The only way to push a 95–96% Pokémon to a true 100%
Silver Bottle Cap
One stat of your choice
- •Raises just one stat (Attack, Defense, or HP) to 15
- •Debuted November 2025 via GO Pass Deluxe "Into the Wild"
- •Useful for fine-tuning when only one stat is lacking
Eligibility
- ✅Buddy level "Good Buddy" or higher — requires ~70 km of walking as your buddy
- ❌Cannot be used on Shadow Pokémon
- ❌Cannot be used on Pokémon that are already 15/15/15
- ❌Hyper Trained Pokémon cannot be transferred to Pokémon HOME
- ❌CP rises permanently — Great/Ultra League Pokémon risk exceeding the 1500/2500 cap. Always simulate first
How It Works
Applying a Bottle Cap to a Pokémon starts Hyper Training.
Choose which stats (Attack / Defense / HP) to boost. Each missing IV point becomes one task (e.g. Attack 12 → 15 = 3 tasks).
You must keep the Pokémon as your active buddy to progress. Only one task per stat can be active at a time.
Every completed task permanently raises the targeted IV by 1. Once raised, the increase cannot be reversed.
You have one year to complete every task after using the Bottle Cap. Going over may invalidate progress — plan ahead.
Task Categories per Stat
Each stat has its own task category, with difficulty escalating from Level 1 to 15. Below are typical examples (buddy slot is required).
* Colors follow the common RPG convention: Attack = red, Defense = blue, HP = green.
