Arboliva is a Pokémon resembling a small olive tree. Its body is white on top, and brown and woody at the bottom. Its head is oval and contains thin, slanted, purple eyes that appear closed. The top of Arboliva's head and its neck are covered with leaves, and two large leavy branches protrude from either side of its upper body. These branches can be bent above Arboliva's head to resemble a wreath. There are three purplish olive fruits on each of these branches, for a total of six fruits. Arboliva's lower body flares out into multiple root-like portions, hiding what appears to be its thin legs at the center.
Arboliva has a calm and compassionate nature, kind enough to share its nutrient-rich, aromatic oil with weakened Pokémon. However, when threatened, it will drive back enemies by launching its oil at them, with a force powerful enough to destroy a boulder.
Arboliva and its pre-evolved forms are the only known Pokémon capable of learning the move Terrain Pulse by leveling up. Arboliva is also the only known Pokémon that can have Seed Sower as an Ability.
Origin
Arboliva may be based on an olive tree, with the fruits on its branches resembling Kalamata olives (or black olives in its Shiny coloration). It sometimes makes a pose resembling the olive wreath in battle. Its calm temperament may be inspired by the symbolism of the olive branch, which traditionally represents peace.
Arboliva may also be inspired by dryads, given its humanoid appearance and compassionate nature. Specifically, it may be based on the Hamadryad, dryads which lived in trees and were sometimes considered a part of the tree itself. Its wreath-like pose might also be interpreted as the indalo, a prehistoric symbol commonly found in the south of Spain.
Name origin
Arboliva may be a combination of arbor or árbol (Spanish for tree), olive or oliva (olive in various Romance languages), and diva.
Orīva may be a combination of オリーブ orību (olive) or oliva and diva.
