Pikachu Meets Shiny Pikachu in Alola

As you can tell by the prompt, this was supposed to be an artwork of Raichu meeting Alolan Raichu as opposed to Pikachu meeting its Shiny counterpart. Oddly enough, the AI still included the white bellies that Raichu have on the two Pikachu featured in this artwork. Perhaps the AI’s bias toward Pikachu got the best of it while making this artwork?
