Ash begins his first-ever Full Battle with Drake, the Orange Crew Supreme Gym Leader.
Ash sends his Snorlax to Professor Oak's Laboratory in exchange for one of his Tauros.
Ash's Tauros and Lapras are revealed to know the moves Fissure and Water Gun, respectively.
Drake's Gengar is able to hover over Tauros's Fissure attack, rendering it useless. While at the time this was impossible in the games, the concept of certain Pokemon, including Gengar, floating to evade Ground-type moves would later be implemented with the Levitate ability.
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.
