Star Fusion
Star Fusion makes a Pokémon stronger with stars: each star raises the damage of every move and attack it lands, up to 5 stars. It is an endgame goal.
How to unlock it
The machine is in Bill's Sea Cottage on Route 25. Talk to Bill and do the quest Bill's Accident: catch a Clefairy and bring it to him. After that, the machine is yours to use whenever you like.
How to fuse

- Click the machine to open the Star Fusion window.
- Drag the Pokémon that stays into the first slot. It keeps everything: level, experience, original trainer, catch date, nickname, held item and moves.
- Drag a copy into the second slot: the same species, the same stars and the same shininess: a shiny only gains a star from another shiny. The copy cannot hold an item or wear addons, an aura or colors.
- Drag one onto the other to swap them.
- Press Fuse. The copy is consumed, the Pokémon in the first slot gains a star and goes back to your Pokébar (or bag).
Every star needs a copy with the same stars, so a Pokémon with 5 stars has used up 31 copies along the way.
A Pokémon with a star can never evolve. Evolve it before fusing: the game asks you to confirm before the first star on a Pokémon that could still evolve.
Damage and cost
Every fusion costs PokéDollars, taken from your bank: the rarity's amount times the number of the star you are gaining. The rarer the species, the more damage per star and the higher the cost.

Where stars show
- On the Poké Ball everywhere (bag, PC, Pokébar, trade, Global Trade Station), under the Pokémon.
- On the map, under the Pokémon's name, above its health bar.
- On the Pokémon's sheet, between the name and the catch date (hover them for the damage bonus).
Stars belong to the Pokémon: they travel with it in a trade, at the Global Trade Station or by mail.
