Torterra

Torterra is a Grass/Ground-type Pokémon who debuts in the Generation IV games, Pokémon Diamond and Pearl Versions and its associated anime series, Pokémon the Series: Diamond and Pearl. Torterra is the second and final evolved form of Turtwig, and it evolves from Grotle at level 32. Torterra is classified as the Continent Pokémon, a classification shared with Groudon. Torterra has Earthquake as its signature move.

Both of Torterra's pre-evolved forms are pure Grass-type, and Torterra the only Pokémon to be a dual Grass/Ground-type. Torterra is invulnerable to Electric-type attacks, but has a quadruple weakness against Ice-type attacks (given how both types are weak to Ice attacks).

Pokémon Diamond and Pearl Versions / Pokémon Platinum Version
In Pokémon Diamond and Pearl Versions and Pokémon Platinum Version, Torterra can only be obtained by evolving it from Grotle, which is also the case in subsequent main Pokémon series titles, although some games require Torterra or one of its pre-evolved forms be traded first.

If Torterra has a high happiness rating, a Move Tutor in Sinnoh offers to teach it the move Frenzy Plant.

Pokémon anime
In Pokémon the Series: Diamond and Pearl, Paul owns a Torterra, which first appears in the episode "Top-Down Training!". Here, it battled the Cynthia's Garchomp but was defeated.

Physical appearance and traits
Torterra are giant tortoises with some prehistoric traits. Some of their attributes make them resemble an, including a giant, flat shell and two large spikes jutting out of the sides of their head. The rim of the shell is white and above their heads is a diamond-shaped extension of the rim. Torterra carry on their shells an enormous tree with soil nearby and three mountain peaks on its back, giving the impression that one is looking at a landscape from a distance. Their bodies are bulky and seem to be too big for their shells. Their bulk no longer allows them to withdraw into their shells as easily as they could as Turtwig, though it gives a sufficient amount of protection from foes. Their main body colors are a dull green on their backs and heads with a brown underbelly and legs. Torterra have several vertical lines running across their backs, though they have fewer lines going across their bellies. Torterra's eyes are intimidating, encircled by a black ring and bearing small red pupils. Their mouth is jagged and at the end of their snout is a dark brown beak, giving them the appearance of a snapping turtle. Their thick, tree trunk-like legs are massive and powerful in order to hold up their enormous, heavy bodies. They bear three toes on each of their legs and appear as if they are actually jagged stones.

Their shell is the basis of their classification as the Continent Pokémon, befitting not only for their shell's appearance, but also for the size of Torterra's actual body. Despite their great size, these Pokémon are peaceful in nature and enjoy being with others of their own kind, preferring to bask in sunlight as they do not like to fight. When immobile, they look as if they are part of the ground upon which they rest, not as though they were a sleeping Pokémon. Because of this appearance, there are occasions when small Pokémon will gather and build nests on the shell of a stationary Torterra. When Torterra do move, they often move in herds in search of water. These herds give the impression of a moving forest. Torterra is the heaviest of all the final evolved starters, and the second tallest, coming in only behind Feraligatr.

Etymology
Torterra's name is a portmanteau of the words "tortoise" and "terra". Its Japanese name "Dodaitose" is a portmanteau of the Japanese word for foundation (土台) and the English word tortoise (トータス).
