"Hah! I'm Blaine, the red-hot Leader of Cinnabar Gym! My fiery Pokémon are all ready with intense heat! They incinerate all challengers! Hah! You better have Burn Heal!"
Blaine's first appearance in the anime series was in the episode IL058: Riddle Me This. In the anime, Blaine had become disturbed by the fact that Cinnabar Island had become filled with tourists, and no serious trainers. This led to the decision that he would close up the Gym and open it in a secret location, and also open a hotel, all the while disguising himself by wearing a long-haired wig, fake mustache, and round sunglasses.
In his disguise, he would give out many riddles to tourists and visitors, including Ash and his friends. With Misty able to figure out many of the riddles, the group found the hidden Gym and figured out that Blaine was in a disguise the whole time. This then led to Ash's gym battle, where he used his Squirtle, Charizard, and Pikachu against Blaine's Ninetales, Rhydon, and the most powerful member of the team, Magmar.
With Squirtle quickly defeated by Ninetales, and Charizard disobedient, Ash was left with Pikachu, who managed to beat Blaine's Rhydon. Blaine then unveiled his Magmar, who was more than a match for Pikachu. When Pikachu was in danger of falling into a lava pit below during the battle, Ash forfeited the match. After an incident where Team Rocket endangered the island, and destroyed the Gym, Ash, his friends, and Blaine had to fix the problem, where Charizard and Magmar developed a rivalry.
Blaine allowed Ash to have a rematch with him shortly after, this time over the volcano where the gym was located. Blaine using his Magmar caused Charizard to participate in the battle. After a hard fought battle, Charizard used Seismic Toss on Magmar, ending it. Upon leaving Blaine rewarded Ash with his Volcano Badge.

In the games[]
Blaine first appeared in the Generation I games as the Cinnabar Island Gym Leader. Before actually getting inside Blaine's Gym however, the player must find the Secret Key to unlock the Gym's door, which is located in the Pokémon Mansion next door. His Gym was filled with quiz machines that unlocked the doors leading up to him. If the player answers incorrectly, they are forced to battle a Gym member.
Rhydon was the second Pokémon Blaine used in his Gym Battle with Ash. It won against Ash's Charizard when it left the ring but lost to Pikachu when it shocked its horn like a lightning rod.
It should be noted that some Rhydon possessed the ability to use Lightning Rod and that all of them were immune to Electric attacks. However Ash's battle with Blaine took place before special abilities were created.
Magmar is Blaine's last, and most powerful, Pokémon. It gave Ash's Pikachu quite a beating before Ash forefit. When Team Rocket froze the volcano Magmar had to clog up a lava flow from the inside. After receiving help from Charizard, it wanted to see how strong it can be so Blaine challenged Ash to a rematch where Ash won the Volcano Badge. Its known attacks are Fire Punch, Fire Blast and Skull Bash.
