This shiny Pokemon may have a competitive advantage in Scarlet and Violet:
The combination dragon- and water-type Pokémon already made a splash in the competitive scene because of its compatibility with Dondozo in double battles. Tatsugiri is able to hop inside Dondozo’s mouth and give it a stat boost. There aren’t a lot of examples of specific Pokémon having contextual interactions with their battle partner, so just as a cool gimmick, Tatsugiri and Dondozo have become a pretty notable competitive team since they debuted inin November.
Tatsugiri has three forms: its curly form, droopy form, and stretchy form. Each form gives Dondozo a different stat boost, and which form you’re using is most readily identifiable by its color. When you have a Shiny Tatsugiri, that makes things a bit trickier, because not only are these different colors than their original, the Shiny droopy form is very close in color to the standard curly form.
