Victor

Victor (Japanese: ビンセント Vincent) is a character of the day who appeared in The Pi-Kahuna. Victor lived on Seafoam Island with his Pikachu, Puka. Puka would always sit on the edge of a cliff, trying to detect the Humungadunga (Japanese: ビッグ・チューズデー Big Tuesday), a huge wave that legendary surfer Jan surfed on many years before. Jan told Victor that he could surf the wave if he really tried. Victor trained for years with Puka until he finally felt he could conquer the Humunga-Dunga. Ash and his friends happened to be on Seafoam Island when Victor was about to surf Humunga-Dunga. The wave hit the island, and Victor successfully rode it with Puka by his side.

Puka
Puka is at least twenty years old, having been first found by surfing enthusiast Victor shortly after he failed to conquer a large wave, "Humunga-Dunga" (Japanese: ビッグ・チューズデー Big Tuesday). Victor was trying to emulate a feat achieved by his surfing hero Jan two decades ago. Puka looks noticeably older and larger than Ash's Pikachu, with wrinkles beneath his eyes. His ears have a different shape, similar to mini-humps, while most Pikachu ears are straight and pointy. His eyes are blue, while Ash's Pikachu's eyes, as well as most Pikachu eyes, are dark brown. Puka can sense big waves coming to the Seafoam Islands beach where he lives, causing his eyes to glow. Incidentally, he does not use any Electric-type attacks throughout the entire episode, even when captured by Team Rocket (Ash's Pikachu does the attacking). Whether Puka can in fact use any Electric attacks is up for debate, since his cheeks do not spark during the episode either.

Puka is rescued by Victor after Team Rocket's submarine is attacked by a family of angry Gyarados. At that moment, Humunga-Dunga makes its scheduled appearance, twenty years after Victor first fell to it. Ash and his friends watch from the beach as Victor, with Puka on his surfboard, successfully ride the big wave and plant a flag atop the rock, right next to where Jan first placed his flag after riding the wave. Puka and Victor return to shore to be greeted by Ash, Misty and Brock, as well as by young children looking up to Victor in awe. In a similar fashion to what his hero did after riding the big wave, Victor tells two young surfers, "You can do it, too!".

Since that episode, Puka and Victor have not been seen again. It can be presumed they remain at the beach house where they are shown to live.
