Doppelgang

, Sutairu kopī, lit. Style Copy (スタイルコピー) is a Green Tech used in. Once Sprigg is recruited in the Temporal Vortex, she automatically joins outfitted with this Tech. Throughout her travels, she can collect enemies in the Forget-Me-Not Pot, at which point, they are added to a collection or pool. Any character can trap enemies to be used for Doppelgang, so long as they have the Pot equipped as an accessory.

This tech allows Sprigg to transform into one of those previously collected enemies, mimicking their stats, their Elements, their strengths, and their weaknesses. Most enemies are trappable, ranging from Acacia PVT to YellowBelly. Even Ozzie, Flea, and Slash can be Doppelganged, after being captured in the Bend of Time, in a New Game Plus game save.

The enemies acquired are also needed for the Grand Slam tournament, which is necessary for recruiting the Demi-human rabbit, Janice. Sprigg can select the exact creature she would like to transform into before the Tech is performed. Additionally, the creatures kept in the pool for her Dopplegang tech determine the randomly summoned monsters that appear in Korcha's seventh-level tech, BigCatch.

Description
When selected, a menu of possible transformations appears. Sprigg selects one and squats down. Wielding her staff, a glyph of green symbols appears at her feet. A green spire of energy rises from the glyphs and envelops her, causing her to disappear. In her stead, the chosen creature materializes, suspended above the ground. It lowers itself and begins to battle.

Name Origin
Doppelgang appears to be a condensed version of, which is a tangible double of a living person in fiction, folklore, and popular culture that typically represents evil. Additionally, Doppelgang may be a portmanteau of Doppel, which means double in German, and gang, a band of individuals united for a purpose or cause. This makes sense, as the Forget-Me-Not-Pot traps duplicates of enemies and keeps them in a collection, or gang, united for the purpose of helping Sprigg transform into them.
