"Cyndaquil protects itself by flaring up the flames on its back. The flames are vigorous if the Pokémon is angry. However, if it is tired, the flames splutter fitfully with incomplete combustion."
Cyndaquil is a favorite among the Johto fans in regards to not only the starters, but to the generation as a whole. He was certainly one of Ash's most adorable Pokemon, as Cyndaquil actually struggled to use its Fire-type attacks at first. But then through training it learned to master its fire, and then became one of Ash's strongest Johto Pokemon.
Cyndaquil's Basic Attacks are Tackle and Ember, while its Special Attacks are Flamethrower, Flame Charge, and Swift.
