Sceptile

Sceptile (ジュカイン Jukain) is the -type Starter Pokémon of the Hoenn region, introduced in Generation III.

Physiology
Sceptile is a large, bipedal, reptilian, gecko-like Pokémon that also possess the traits of dinosaurs. It has powerfully-built limbs and muscular legs that allow it to run at high speeds to chase after its prey in the jungles where it lives. Its body is mostly vivid green in color, and it has a gracefully rounded belly with a horizontal, pale red stripe extending across it. It has a light red chin and narrowed eyes with small, slit pupils and yellow scleras, with a red rim around the outsides. It has bladed leaves on its wrists, which it uses to slash (using Leaf Blade). It has a long, large dark green, fern-like plant that resembles a tree for a tail, and a cluster of small round yellow nutrient-rich seeds growing on its back. It has three sharp green claws on both its hands and toes.

Special Abilities
Seeing as it has leaves as sharp as swords growing from its body, Sceptile can learn powerful slashing moves. It learns Leaf Blade, X-Scissor, and Night Slash by leveling up, and Dragon Claw by TM. It has ability Overgrow which increase its Grass-type attacks by 50% when its HP gets lower than 1/3. It is extremely agile and swift. The seeds on its back are full of energy which provides trees with revitalizing nutrients.

Behavior
Sceptile is an incredible, swift hunter of the forest. It uses its bladed leaves to strike down its prey and battle its foes. It also cares deeply about the plants and trees in the forests where it lives, and raises them with loving care. Being a reptile, it is cold-blooded, and must regulate its body temperature by basking in the sunlight.

Evolution
Sceptile is the final evolution of Treecko, by having Grovyle up to level 36. Sceptile can further evolve into Mega Sceptile using its Mega Stone.
