Artist's Note:
Never argue with video game logic, especially when it's a game meant for children.
Writer's Note:
The complaints about Solgaleo's steel/psychic typing remind me of a time, WAAAAAAY back in the day, when people were bitching about Solrock's typing in Ruby and Sapphire. Naturally there was no Reddit or Twitter back then, so the bitchfest mostly unfolded on obscure gaming forums, but even so the structure of the complaining was basically identical and the content equally silly. Pokemon has always been a children's game, which doesn't mean that adults can't enjoy it, but rather, it was designed to be enjoyed with a high degree of suspended disbelief, free from the manic over-analysis that internet fandom culture tends to apply a bit too liberally.
