Nicholai (Japanese: キヨ Kiyo) is a Pokémon Trainer in Hoenn who is obsessed with short pants and cosplaying as Pokémon. Nicholai was May's first opponent in a Pokémon battle.
He first appeared in In the Knicker of Time!. Ash, May, Brock, and Max were traveling through the Petalburg Woods on the way to Rustboro City. They were surprised to see a gigantic Zigzagoon. It was actually Nicholai in a costume. He was trying to lure the wild Zigzagoon closer so he could battle them. Ash and his friends scared the Zigzagoon away, and Nicholai introduced himself to the group. The boy then showed off his collection of Pokémon costumes.
Nicholai explained that he believed that his costumes allowed him to know what a Pokémon felt like. In addition, the costumes helped him blend in with wild Pokémon. Nicholai wanted a Zigzagoon so he could challenge Norman at the Petalburg City Gym.
After learning that May was Norman's daughter, Nicholai excitedly challenged May to a Pokémon battle. Nicholai sent out his Mudkip and May used her only Pokémon, Torchic. Mudkip easily knocked out Torchic with a couple of Water Gun attacks. Nicholai then concluded that since May lost so horribly, Norman must be a pushover in battle, too.
Max, angry at Nicholai for insulting his father, followed him. Apparently he was still trying to capture a Zigzagoon. Max stole Nicholai's Pokémon bait, and ended up surrounded by a pack of the Normal-type Pokémon. Ash and the others rescued Max. Eventually, with the help of his Mudkip, Nicholai caught a Zigzagoon.
Team Rocket tried to steal Mudkip, but Nicholai used a Gligar costume to fly up and rescue the Mud Fish Pokémon. Pikachu then blasted Team Rocket off with an Electric-type attack. Nicholai used his new Zigzagoon in a battle against Ash's Taillow before parting for Petalburg City.
His second and final appearance was in ZigZag Zangoose!. When Ash and his friends were traveling to Fallarbor Town, they once again met Nicholai on Route 111. This time he was dressed up as a Zangoose and he had a new Zangoose of his own.
Nicholai informed the group that he had challenged Norman, but was defeated. May and Max's mother told him where they were headed so he came to meet them. He battled Ash: Treecko versus the newly evolved Marshtomp. Treecko managed to win.
When Team Rocket tried to steal Nicholai's Marshtomp, his Zangoose came to the rescue. He battled with Seviper and defeated it with a powerful Crush Claw.
After Team Rocket were blasted off, Nicholai and Ash had one last battle, though the winner was not revealed.

| Nicholai's Zigzagoon first appeared in In the Knicker of Time! where Nicholai was chasing a bunch of Zigzagoon so he could catch one. After seeing Nicholai using one of Zigzagoon's favorite food, Max tried to lure them in but was confronted by a giant hungry pack of them. Nicholai found out what to do and sprayed all the trees with water to knock the Berries out. Then he asked to battle Zigzagoon, and after a tight fight Nicholai caught it. Then Zigzagoon was used in a battle against Ash with his Taillow, but who won is unknown.
It appeared later in ZigZag Zangoose where it battled Ash and his Pikachu, but again, who won is unknown.

- Nicholai is based on the Youngster Trainer class. In the Japanese version, he even calls himself たんパンこぞう Shorts Boy, Youngster's Japanese name, though he also has similarities to the Poké Maniac who dresses up as a Pokémon.
- Nando, who battled May's successor, Dawn for her first official battle, also went on to become a recurring character.
