Magmar

Magmar's body always burns with an orange glow, which enables it to hide among flames. In "Riddle Me This" Ash and Blaine, the riddling Pokemon Gym trainer from Cinnabar Island, are locked in fiery combat. In the explosive final conflict, Blaine lets loose his super-hot and super-rare Magmar to do battle against Pikachu. Since Pikachu is no match for Magmar, Ash wisely chooses to surrender rather than lose his best friend.
