As a Pokémon expert, I can guide you through the process of evolving Staryu in the Pokémon games. To evolve Staryu into its final form, Starmie, you need to increase the friendship or affection level that Staryu has for its trainer.

Here are some ways to increase the friendship between you and your Staryu:


1. Avoiding Battles: Staryu likes it when you avoid battles, so using it less frequently can help.

2. Walking with Staryu: Having Staryu in your party while you walk around can increase affection.

3. Using Items: Items like Soothe Bell, which increases the rate at which Pokémon gain friendship, can be beneficial.

4. Healing with Items: Using items like antidotes or status-restoring berries can also help.

5. Praising in Super Training: If you're playing a game with Super Training, praising Staryu after a match can increase friendship.

Once you've increased the friendship enough, trading Staryu to another player and then trading it back to you will cause it to evolve into Starmie. This is because the trade itself acts as a catalyst for evolution when the friendship level is high.
