>>46025823His first pokemon were a Wimpod and an Alolan Vulpix. For bug specifically, kids in his hometown used to bully the Wimpod that lived nearby, and that was something that upset him a lot, so when he was a kid he'd try to fight the bullies and protect the Wimpod, and usually get beat up a lot. It's a pretty important part of his development, because it lead to him feeling closer to pokemon than people, and generally disliking people as a whole. But, it's why he wanted to show people that bug types can be strong too, because he hated people picking on bugs for being weak and vulnerable. Ice is just another weak type, and he likes Vulpix a lot, so he ended up feeling similarly about ice.
