Ash's Torterra (Japanese: Satoshi's Dodaitose) is a Grass-type Pokémon owned by Ash Ketchum.
Torterra was first caught as a Turtwig after battling Ash and his Pikachu.
Turtwig has battled many opponents before:
Paul's Chimchar, Roark's Rampardos, Gardenia's Turtwig, and Crasher Wake's Quagsire.
While battling Paul's Honchkrow in DP100, Turtwig evolved into Grotle, but lost due to its lowered Speed. But after learning how to cope with its defense from
Paul's Torterra when it fought Gliscor, Ash managed to make Grotle stronger and Grotle learned Rock Climb. Since evolution, Grotle managed to defeat foes like Candice's Sneasel.
After being used in a gym battle against
Volkner, which got postponed, Grotle evolved into Torterra during a battle with Team Rocket.
With its new size and strengths, Torterra now knows more powerful moves such as
Leaf Storm in addition to the moves Energy Ball, Rock Climb and Synthesis. Despite its size and power, it has been defeated in several battles against Pokémon it should have an advantage over: Volkner's Electivire, Bertha's Hippowdon and Paul's Drapion.
Ash decided to leave Torterra at
Professor Oak's Lab when he made a fresh start for Unova. It currently resides at Professor Oak's Lab.
Torterra will reappear along with all of Ash's Pokemon in an upcoming episode of Best Wishes Season 2.
Turtwig sent out
Ash and Torterra
When it was a Turtwig, Torterra's way of showing affection was by biting on someone's head.
Torterra is the only Pokémon in Ash's Sinnoh team that has never defeated any of Paul's Pokémon.
As a Turtwig, Torterra was active and very quick, but when it evolved into a Grotle, Torterra lost it's speed and became less active.
Throughout it's evolution, Torterra has relied on specific stats to battle.
As a Turtwig, Torterra relied on speed, accuracy and evasiveness.
As a Grotle, Torterra relied on defense, patience and precise attacks.
As a Torterra, Torterra relied on attack power, strength and healing.
After evolving from Grotle to Torterra, its was the first time Ash had two fully-evolved starter Pokemon from the same region.
Torterra has not learnt a Ground-type move, despite being a Ground-type.
