The Insects That Inspired Pokémon's Origin
As a child, Satoshi Tajiri, the creator of Pokémon, was captivated by the insects he found in the fields near his home in Japan.
His passion for collecting and studying these small creatures not only shaped his childhood but also became the seed for the creation of one of the most iconic universes in video game history.
In this article, we will explore how Tajiri transformed his love for insects into a global phenomenon, focusing on those first-generation Pokémon directly inspired by these fascinating beings.
We will analyze similarities, differences, and the unique abilities he added to his creations, showing how reality and fantasy unite in the Pokémon world.

Similarities
Both Caterpie and its real-life counterpart share the same basic design, including prominent eyes that appear intimidating and a segmented body.
