Randy

Randall is a character of the day who appeared in Kindergarten Chaos!. He is one of the students in Penelope's kindergarten class. Randall doesn't have anything against Pokémon, but he is shown to be very timid around them.

While the other kids were playing with Ash and his friends's Pokémon, Ash noticed Randall in the distance running away. The kindergarten principal tried to get him to meet the Pokémon, but he was reluctant to get close to Froakie or Dedenne, even when assured by Ash and Bonnie that there was nothing to be afraid of. Randall revealed that his fear of Pokémon was because of a previous incident involving a Beedrill. Though Ash and his friends tried to reassure him again, Randall was still convinced that Pokémon were scary.

Suddenly, Team Rocket pulled up in front of the school, disguised as children's entertainers, causing everyone to run up to the entertainment, with Randall being dragged along and up onstage. When Team Rocket's scheme was revealed, everyone else escaped, but Randall, along with Pikachu, Froakie, and Penelope's Sylveon were left in the stage truck on their getaway. While in the truck, when he realized Sylveon and other Pokémon were friends and not tricksters, Randall finally got over his fear of Pokémon. Therefore, he desired to help save the captive Pokémon together with Ash, which they both accomplished with force.

After Ash defeated Team Rocket, Penelope took them back to the kindergarten. After sharing his story of saving Pikachu and Sylveon to the class, Randall reiterated that Froakie and the other Pokémon were his friends, which Ash seconded. Upon bidding farewell to Ash and his friends, he agreed to have a battle with Ash in the future.
