Serperior (Japanese: ジャローダJarouda) is the Grass-typeStarter Pokémon of the Unova region, introduced in Generation V. It is classified as the Regal Pokémon. It has the ability Overgrow. It is the final form of Snivy, one of the three Unova starters. This Pokémon raises its head high to intimidate opponents. It only becomes serious when fighting a strong enemy.
Serperior is a serpentine Pokémon, much like Dratini, Dragonair, or Seviper. However, it is the first Grass-type serpentine Pokémon. Serperior is green with some yellow designs on it, kind of like Rayquaza. The small wing-like protrusion is now a collar. It sprouts small, stubby hands. Its red eyes are also relatively small in comparison with Snivy's. It also has a long green tail with three leaves sprouting from it. Also known as the Regal/Royal Pokémon, Serperior is very different from its first evolution, Snivy.
Serperior's name is a combination of the words "serpent" and "superior."This is the second Pokémon to have its name based on the word "superior," with the first being Rhyperior.
Serperior is based on western culture (royalty), whereas Samurott and Emboar are based on Japanese and Chinese culture, respectively.
Unlike other snake-based Pokémon such as Arbok and Seviper, Serperior is not even part Poison-type.
Despite being the final stage in a 3-Pokémon evolutionary chain and having a base stat total of 528, Serperior still has the same Special Attack stat as an Oddish (and the same Attack stat as a Bellsprout).
Serperior is the tallest Pokemon in Generation V.
Serperior is very different from it's first evolution, Snivy. It's appearance changed dramatically.
