He is the leader of the Orange League. Trainers who defeat him in a full battle at Pummelo Stadium receive the Winner's Trophy and enter the Orange League Hall of Fame.
Ash Ketchum battled him in Hello, Pummelo! and Enter The Dragonite. His Japanese voice actor is Koji Yusa and his English voice actor is Scottie Ray.
Although the dub implies that Drake is merely a fifth Gym Leader in the Orange League, the Japanese version specifically uses the title Head Leader to denote his importance. Additionally, Drake is not necessarily a League Champion, either, given that it is not clarified whether or not he ever actually had to defeat a previous Head Leader in order to take the title (though it is suggested). In the Electric Tale of Pikachu manga, he is referred to as the Orange Crew Supreme Gym Leader. Ash battles him in Surf's Up, Pikachu.
In both anime and manga, Ash was the first person to defeat Drake in Orange League history. Many trainers never even got past Drake's first Pokemon, Ditto, apparently losing their cool seeing a copycat defeat their own Pokemon. Before Ash's challenge, Drake seemed bored and wondered if anyone would ever defeat him. He keeps his prized Dragonite's Poke Ball around his neck.
Regardless of his English name and his affinity for Dragon-type Pokemon, Drake apparently has no relation to either Drake of the Hoenn League nor Lance of the Indigo League, though a resemblance to the latter is evident.
