If you thought Professor Sycamore would have fans "fangirling," then wait for Alola's Professor Kukui.

Professor Kukui

The Pokémon Company International revealed a few new characters on June 2, coincidentally following Japan's airing of the "Pokémon XYZ" airing of Ash trying to win his next gym badge -- but no spoilers here on that battle.

One character is Professor Kukui, who has been confirmed to be the Alola region's Pokémon professor. He is regarded as "passionate" about his study of Pokémon moves, even being the recipient of such Pokémon attacks.

"Sporting a white lab coat, Professor Kukui has his own unique style," The Pokémon Company International noted, which can be seen in his official art as he sports a white hat with a rainbow, shirtless but with a lab coat and gray shorts. He also sports glasses with green frames.

Hau

Being the same age as the video game player's chosen character, Hau is said to be a "Pokémon-loving young boy with a big appetite," and likely one of your rivals who will also select one of the three starter Pokémon. He is confirmed to be one of your friends, meaning he'll be friendly, but surely will offer an intense Pokémon battle as the Alola journey continues.

Hau's clothing style also follows the Hawaiian or Pacific-influenced Alola region, with yellow and orange colored shorts, a black shirt, orange shoes and considerably tanned.

Lillie

Kukui isn't alone in the laboratory as he has an assistant. Also in the same age group as Hau, Lillie is considered as a "mysterious" girl who is not fond of Pokémon battles, since she opposes fights. Lillie enjoys reading and will play an important role in the "Pokémon Sun" and "Pokémon Moon" storylines.

Lillie is definitely dressed differently compared to Hau and Kukui as she sports a dress-like attire, high socks, long blonde hair, and a big hat. In her official art, she carries a bag with a Pokémon logo, which may carry something very important to the storyline.

The three characters were revealed along with the mascots of "Pokémon Sun" and "Pokémon Moon," Sungaleo and Lunala, respectively. For more details about the new legendary Pokémon, click here.

"Pokémon Sun" and "Pokémon Moon" will be available for the Nintendo 3DS on Nov. 18.
