Ash's Tropius (Japanese: サトシトロピウス Satoshi's Tropius) is the twenty-third Pokémon that Ash Ketchum caught in the Unova region.
It later reunited with Ash and the entire Unova team at Oak's lab in The Dream Continues. Tropius joined in with them to launch a group attack on Team Rocket, using Magical Leaf to send them blasting off for the final time in the Best Wishes series.
