Buizel is a Water-type Pokémon resembling a weasel or river otter. It features brownish-orange fur accented with yellow, a distinctive inflatable flotation sac around its neck, and two propeller-like tails. Blue fins on its forearms aid its swimming. Gender differences appear in yellow spot patterns: two spots for males, one for females.
Initially owned by Coordinator Dawn, Buizel strongly preferred battles over contests. This goal mismatch led to a trade with Ash Ketchum, aligning better with Buizel's competitive drive. The Pokémon exhibits confidence, determination, and occasional mischievousness, frequently seeking challenges to test its strength. Buizel demonstrates tactical adaptability in combat, utilizing the environment and opponent weaknesses, though it sometimes acts impulsively without considering long-term consequences.
In battle, Buizel employs physical speed and aquatic techniques. Its signature moves include Aqua Jet for high-speed rushes and Aqua Tail for powerful strikes. It also utilizes Ice Punch and Sonic Boom, showcasing versatility beyond typical Water-type attacks. Its battling style emphasizes agility and rapid strikes, reflecting its inherent Speed.
A defining arc occurred during the Sinnoh League when Buizel faced Ash’s rival Paul. It demonstrated strategic ingenuity by using Whirlpool to counter terrain disadvantages and executing close-range Ice Punch tactics. This battle underscored its growth from a headstrong fighter into a more calculated combatant. Outside formal battles, Buizel maintained playful interactions with other Pokémon but remained fiercely independent, often resisting rigid training routines in favor of instinct-driven practice.
