Pokémon Black & White
Emile backtracked all the way from Castelia City in order to take advantage of an NPC who was giving away free Berries. He asked to see a Rock-Type Pokémon in exchange, and as Roggenrola was the only one currently obtainable, Emile returned to Wellspring Cave. He sent out his Sandile against the first one he found, a Level 11 female, who used Harden first and then Headbutt in response to Sandile's Sand Tomb, the first attack having missed. Emile tossed a Nest Ball and succeeded in catching her, and then nicknamed her. He put her in his party in place of Lillipip and returned to Castelia City, earning a Pecha Berry for his efforts.
While healing Haywire following the battle with Dancer Edmond, Emile noticed that he still had BACKTRAKNG in his party, finding humor both at having forgotten to deposit her and at seeing her nickname. He deposited her again offscreen.
BACKTRAKNG, along with the rest of Emile's catalog of Pokémon, was seen in the PC when Emile was looking for a Pokémon to teach Fly.
BACKTRAKNG has a Docile Nature, which neither helps nor hinders any stats.
- Tackle (Pre-Episode 12–Present)
- Harden (Pre-Episode 12–Present)
- Sand-Attack (Pre-Episode 12–Present)
- Headbutt (Pre-Episode 12–Present)
BACKTRAKNG is a capitalized corruption of "backtracking", referring to Emile's frustration at having to backtrack from Castelia City to Wellspring Cave to catch her. Necessity was later caught to make the concept of backtracking easier by way of newly-obtained Fly HM.
- For the entire time that he was battling BACKTRAKNG, Emile ranted about how Roggenrola looked so much like a pencil sharpener and how nobody had yet taken advantage of that as a marketing strategy.
