The Genwunner

''"Anything beyond the original 151 Pokémon isn't a Pokémon!" - The Genwunner''

The person who believes the first of something (like the first season of a TV show or first installment of a video game series) is the only one that actually matters in comparison to the later installations. They may see this as true as they believe these additions to the franchise do what the original did wrong or don't do it at all, making them inferior to what the franchise in its earlier times was. There is a word out there that one might use to address a Genwunner.

The Genwunner got their name from genwunners in the Pokémon fanbase who believe the only real Pokémon games were Pokémon Red, Blue, Green, and Yellow while everything proceeding is a spit-in-the-face to the initial image of Pokémon.

Note that a person can only be counted as a Genwunner if they think that the single first of their franchise is good, not the first few.
