I just had the most adorable headcanon.
Headcanon that Guzma loves all Bug type Pokemon, regardless of how they look.
From the terrifying Golisopod to the Tastes-Like-Diabetes level of cute in Cutiefly, he doesn’t discriminate.
Speaking of Cutiefly, sometimes, if he’s in a super good mood, a swarm of them appear and linger around him for a bit. Harming them leads to severe repercussions, although he will let his grunts catch them if they want one and swear to take care of it.
