Ash's Greninja

Ash's Froakie is a -type Pokémon that made its debut in XY001: Kalos, Where Dreams and Adventures Begin!. It is the first Pokémon caught by Ash in Kalos.

Biography
Froakie first appeared when he observed Pikachu shocking Bonnie, Clemont and Ash outside the Lumiose Gym. It followed the group to a nearby park, where it watched the trio talking from a tree. When the group were attacked by Team Rocket, Froakie protected Pikachu from its own Electro Ball, which had been rebounded by Wobbuffet's Mirror Coat. After Team Rocket were sent blasting off, Froakie fainted and Ash took him to Professor Sycamore's lab.

Eventually, Froakie was healed at Sycamore's lab. Froakie was present when Team Rocket tried to take control of Professor Sycamore's Garchomp and assisted Ash in his attempt to help. When Garchomp was about to fall off the Prism Tower, Froakie used some of the sticky bubbles on his back to stick Garchomp's feet to the floor and prevent it from falling. This then allowed Pikachu to destroy the machine controlling Garchomp with Iron Tail. At the end of the episode, Froakie appeared in front of Sycamore's lab with a Poké Ball and asked Ash to catch it, which Ash did so gladly.

Appearance
Like most other Froakies, Froakie looks like a frog and seems to have the same stance as one.

Personality
Froakie seems to be a tough Pokémon in reference to his personality. He left many of his previous trainers as his natures didn't meet with them. He finally chose Ash after seeing his bravery.

Trivia
