Pikachu

The final aspect of Pokemon Yellow that hasn't chnaged a bit is your Pikachu. This Pikachu is unlike any other, much like Ash's in the Anime Series. This Pikachu will follow you outside of its Pokemon (when healthy), and will even give off a number of emotional expressions if you talk with it or when doing a few things in game. This Pikachu, as in the original copy of Yellow, cannot evolve and will surprisingly learn Thunderbolt at Level 25.
