Approval of God: The Galarian forms of Zigzagoon, Linoone, and the Galarian-exclusive evolution Obstagoon bear more than a striking resemblance to and are clearly inspired by KISS's black and white makeup and leather-clad metal armor. Band front runner Gene Simmons, who is notorious for taking legal action against parodies and rip-offs of the band's likeness, is a fan of the series and is actually cool with the designs.
Together, the games have garnered the nickname "Pokémon Swish", which is created by taking the first two letters of both games' names and putting a vowel between them. Helps that it sounds like Pokémon Switch and that it makes a fun swishing sound.
Following the trend of naming the protagonists after the games, people felt iffy on the idea of literally calling the boy and girl "Sword" and "Shield" respectively, and took to finding more traditional names that sounded similar.

A t-shirt design contest by UNIQLO promised that all winning shirts would be officially produced and available in stores, in addition to the grand winner getting their t-shirt in the game. While that t-shirt was disqualified for being sold elsewhere beforehand, and another shortly after once it came to light that it was using stolen fanart, the rest will still be made, arriving in stores in late June.
What Could Have Been: There was a t-shirt design contest hosted by UNIQLO, where the winner was a shirt with a Magikarp and Gyarados design, with screenshots showing the winning t-shirt in-game. However, the winner got disqualified as they've been caught using the design for commercial use before. As a result, the design was disqualified from the contest and removed from the game. It was decided that a replacement will not be picked, despite the other designs following the rules.
