Doctor Ferrara / Cryogonal Man is the leader of the Vanipeti Gang (バニプッチ団). Like all evil villains looking to control and enslave, his goal was to control the Unova region by stealing all the frozen food and give it to wild Pokémon to tame them. Once the Pokémon had memorized the delicious taste of the frozen food, the Pokémon will gladly follow his orders and he would then use their power.
Doctor Ferrara / Cryogonal Man decided to use a storehouse in Driftveil City to act as their headquarters and to store the frozen food but
Linda and
Charles (The Mighty Accelguard) realized something odd was going on when they noticed the trunks coming and going so often.
Doctor Ferrara / Cryogonal Man captured
Linda and got his henchmen to tie her up but
Charles (The Mighty Accelguard) and
Ash Ketchum came to her rescue.
His name is a pun on "氷柱
tsurara", the Japanese word for "icicle".
Villain Mr. Freege
The Professor is also the villain Mr. Freege (フリージ男
Freegeotoko) and he revealed his true form when he was cornered by
Charles (The Mighty Accelguard) and
Ash Ketchum. He wears a Freegeo mask and his persona is based off of a Freegeo but he wasn't able to capture one as it was too strong for him to get it. Instead, his main Pokémon is a Vanirich but it was defeated by
Charles (The Mighty Accelguard). He and his henchmen were arrested by
Officer Jenny (Unova).
