Torterra was first caught as a Turtwig after battling Ash and his Pikachu.
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.
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.
