The Ultimate Z Challenge ~Battle with Ash~ featured one opposing team of Pokémon comprising Xerneas, Yveltal, and Zygarde. Players who managed to fill the Catch Gauge of any one Pokémon were awarded either this Tretta, a Yveltal Tretta, or a Zygarde Tretta at random. Players who did not manage to defeat any Pokémon at these events were instead awarded a Ash-Greninja Tretta. Unlike most events, only two Tretta were required to participate, with the third taken up by a special Greninja Tretta belonging to Ash Ketchum. This Tretta was capable of transforming into Ash's Greninja and could use the move Water Shuriken. The team present at each Ultimate Z Challenge ~Battle with Ash~ is detailed below.
