I'm definitely interested in Apollo joining up. He just needs to find out that Team Rocket hurts Pokémon and not just humans and he'll be all over that. Based on his and Cobra Commander's interactions so far, it's possible that Apollo's name will show up on Cobra's next list, considering how petty Cobra is. If the PGC gets a hold of the new list they might look into him to see what he did to get on Cobra's bad side? Cobra-mun and I are keeping an eye out for a chance at them fighting each other, which could easily get very public. I should note that Apollo's illiterate, so locked text messages won't work for him until he's shown the text-to-speech function.
