There are three stages of discovery as a person plays Pokemon
1. Discovering that there are Pokemon other than Pikachu
With the television show, the video game, card game, and comics featuring Pikachu as a protagonist, it is often a bit of an epiphany for a person to realize that they have a degree of freedom with their favorite Pokemon, even if they discover this immediately when they turn on the game or open a pack of cards. This epiphany is especially strong for younger players, since age-appropriate media almost uniformly features Pikachu, and it's a bit of a leap of brain processes when they realize that even though Nintendo wants them to like Pikachu, they can like something else instead.
For some people, realizing that they can like other Pokemon or even just like a bunch of Pokemon leads them towards exploring these options, and some people even end up preferring them. Pokemon allows a degree of freedom that other games don't provide, and being able to choose from a wide variety of creatures is appealing to many people.
2. Discovering that Pikachu is the worst Pokemon
Most people find that anyone who likes Pikachu is inevitably some entry-level casual. They have one foot in Pokemon but they're not quite there; they're just fake fans that recognize the yellow mouse. Delving deeper could have unwanted consequences so it's safe to just like Pikachu.
With other Pokemon, you can like anything you like. Eevee, Charizard, etc. You can like something cute like Pikachu is or you can like something totally different.
Liking Pikachu is like broadcasting that you're just an entry-level Pokemon fan, so Pokemon fans don't like you, but people who like Pokemon also don't like you because they think you like Pokemon.
3. Discovering that Pikachu is the best Pokemon
This is a discovery that not everyone makes. Countless people live and die without realizing the simplest of truths.
Pikachu isn't just appealing to people who don't actually like Pokemon; Pikachu represents everything that Pokemon is about. Liking Pikachu correlates perfectly with liking Pokemon. Pikachu is the face and representative of Pokemon. Pikachu isn't just something that is merely a marketing or advertisement tool; delving deeper into the series shows that Pikachu represents every aspect of the franchise and embodies what Pokemon has always stood for and will always stand for.
