May's Blaziken evolved from
May's Combusken when Team Rocket was attempting to steal Pikachu during the break at a Pokémon Contest. Just after it evolved it learned
Blaze Kick and used it to blast Team Rocket away.
May was happy and amazed that her Blaziken defeated Team Rocket and had learned
Blaze Kick at the same time.
Initially the battle was going to be between
Ash's Sceptile and
May's Combusken but
May's Combusken evolved and
May used Blaziken in the final round.
Ash Ketchum realized that his Sceptile had the type disadvantage in the battle but he was confident that it was strong enough to overcome the type disadvantage. This was
Ash Ketchum's first contest battle and
Ash's Sceptile initially missed a few times and lost points because
May's Blaziken dodged the attacks. Realizing that he needed to be more accurate with the attacks and effectively use Sceptile's speed,
Ash Ketchum managed to back
May's Blaziken into a corner to land some attacks accurately and effectively. The battle proved to be a fierce tug-of-war as neither Pokémon backed down. With
Ash's Sceptile exhausted to the limit, Overgrow activated but at the same time
May's Blaziken Blaze was activated and the two of them regained their power. With only a few seconds remaining in the battle, the two Pokémon went into a direct head-on fight and launched their two most powerful attacks:
Overheat and
SolarBeam which exploded in the air causing a huge smoke cloud to form and made it hard for people to see the results board. When the smoke cleared, the results board showed that the battle end in a tie.
