So yesterday I was chilling with my brother and he decided to run the elite 4 in the alternate dimension, his version being Sun so he went to "Moon". Up until this point he had ran the elite 4 a few times in the regular dimension and had the regular alternating between Kukui and Hau. Then in the alternate dimension, he fought Hau the first time and the second time, he fought "Preschooler Tristan". Now I don't have photo or video evidence of this but believe me its real.

Has anyone else seen this mystery bab?
