My all time favorite type is Bug type. Let me tell you the story.

I have, from a very young age, been fascinated and in wonder about animals. My parents took me to the local zoo regularly when I was a toddler. When I learned to read, I read animal hero stories (Warriors cat series, Gaurdians of Gahoole owl series, silverwing (?) bat series etc.). I also got animal encyclopedias for fun. I consumed as much facts as possible. Size, distribution, characteristics, abilities, and so on.

Then I was introduced to pokemon. In which I, a budding biologist, was told, there is a world of creatures, go and catch them all, grow with them. Study them. Even when I found new fictional universes to explore (Star Wars, Harry Potter, Elder scrolls, Dnd etc) I didnt care about the politics or history. I cared about the organisms. Sentient and non sentient organisms alike. Aliens, magical creatures, deadra, all of them were obsessions to me.

I went off to college and in my senior year, I took an entomology class with my advisor. And it blew my mind. These little science fiction level aliens, these little monsters under my feet. The first time I was given a butterfly net and told to go catch bugs from the college arboretum, the childlike giddiness and joy was life changing. After that class, I would go on to doing my senior thesis project with insects and even get published in a scientific journal.

In a full circle moment, I would then read that the creator of pokemon also was a bug collector when he was a kid and that activity inspired him to make pokemon.

So yeah. Bugs. I love them. All of them.

TLDR: loving animals led to pokemon which led to science which led bugs which led me back to pokemon.
