The Pokémon Game Franchise is what started it all. The original versions of the games were released for the Gameboy Color around the world between the years of 1996-1999. Every few years Nintendo releases a new updated set of games that either, retell a previous plot, or tell a new story entirely. So far, Blue, Red, and the Kanto Gym Leaders are the ONLY characters who appeared in every generation.
Information on Blue that can be learned from a precursory glance at his character. This section includes information on both Blue and his party and deals with the surface layer of his character.
Blue is one of the most important characters in the first Generation Games so it should come as no surprise that there is a lot of depth to his character (when compared to most characters in the game). In order to understand the Blue of the game, you have to look beyond his anime & manga counterparts.
