Alakazam starts things off by launching a powerful Zap Cannon toward Umbreon, but misses when it leaps into the air in the nick of time. Alakazam then tries Psychic, but Umbreon is unaffected by it as a Dark-type Pokémon. Using its Headbutt next, Alakazam charges at its opponent with alarming speed. However, Umbreon dodges and takes advantage of the situation by tackling Alakazam. Alakazam recovers from the blow and retaliates with Dynamic Punch, which Umbreon easily evades. Alakazam then pulls off a Double Team and sends all clones to strike at once. Gary commands Umbreon to stay calm to sense the real Alakazam, which it does. Just as Umbreon is about to connect with a Quick Attack, Alakazam uses Teleport and disappears. As Umbreon searches for the whereabouts of its opponent, Alex tells Alakazam to end the battle with Hyper Beam. Gary notices the strange light coming from his left and warns Umbreon to dodge the attack. Umbreon jumps up at the last second and finishes Alakazam off using Hidden Power. Seeing that the battle is over, Ash rushes up to Gary and challenges him to a battle as well, but Gary declines, reminding Ash of how Umbreon defeated Pikachu before as an Eevee. Ash tells Gary he doesn’t have to use Pikachu to battle Umbreon, and sends out Chikorita, Cyndaquil, Totodile, and Noctowl. However, Ash’s attempts to impress his rival backfire as Chikorita goes straight to Ash for attention, Cyndaquil wanders about aimlessly, Totodile starts dancing around wildly, and Noctowl falls asleep. Ash starts to despair, but by now Gary has walked off. Naturally, Ash isn’t happy about the brush off and vows to beat Gary and Umbreon the next time they meet.
