Sceptile is a Pokémon owned by Ash, which he caught as a Treecko while venturing through Sinnoh.
Sceptile is known to act cool, calm and collected, liking to hold a twig in the side of his mouth.
Sceptile has an overpowering pride, similar to Buizel, that he will defend at all costs from anyone or anything that damages it.
Sceptile developed a crush on Nurse Joy's Meganium, becoming very aggressive towards a Tropius that also had a crush on Meganium. After Meganium showed herself to like Tropius, Sceptile was heartbroken and temporarily lost the ability to use his moves.
As a Grovyle, Sceptile would sometimes tease the other Pokémon, especially Corphish.
