Sceptile is a reptilian, bipedal Pokémon. Its neck is somewhat long, and it has two crests on its head. It has semicircular, yellow eyes with red rims. Its lower jaw and a belt-like band across its waist are also red. Along its back, it has two lines running down the middle and two rows of yellow nodules that are described as seeds. Its tail is shaped similar to that of a palm tree's branch. Both of its long arms have two sharp, elongated leaves and three claws.

Sceptile is a jungle-dwelling Pokémon. It has no equals in jungle combat. The seeds on its back contain nutrients, which are said to be able to revitalize trees. As mentioned in Sleep Style Dex, it is believed that the unique seed ability of Sceptile helps nearby tree saplings grow and thrive when it is asleep. It is capable of leaping freely from branch to branch. While it has the ability to slice down thick trees, it is known to care lovingly for the plants in the forest. This Pokémon regulates its body temperature by basking in the sunlight. Sceptile is said to have no equal or rival when it comes to combat in the jungle.

Forms
Sceptile can Mega Evolve into Mega Sceptile.

As Mega Sceptile, its head crests become more pointed with a round portion missing from the middle. Red marking surrounds its eyes, which become smaller and more narrow. The yellow seeds down its back grow larger. The seeds on Mega Sceptile's back are filled with energy thanks to Mega Evolution. The last pair of seeds turn red, while the pair above it turns orange. Red stripes encircle the base of its tail and run across its lower belly. The leaves on its wrists become more pointed, and the upper ones have red tips and half-circles cut out of the middles. Covering its chest and shoulders are plates of leaves similar to those that form its tail. Mega Sceptile's tail grows longer and develops a red stinger at the tip.

Mega Sceptile can cut off a portion of its tail to fire it like a missile at an opponent. Mega Sceptile can also detonate the seeds on its back and lower tail to launch its tail tip. Its lost tail will continue regenerating as long as it still has the energy required for Mega Evolution. Mega Sceptile can move to its opponent very quickly in a flash thanks to its fast legs.
