Yellow (イエロー) is a character of the Pokémon Pocket Monsters manga. He is based on Red from the original Pokémon Red and Green.
Yellow first appears in PM044. He looks similar to Red and even has a Pikachu like him. At one point he disguised as Red, pretended to be him and committed all kinds of evil deeds.
Personality and characteristics
Yellow is considered to be very sneaky as seen when he tried to pretend to be Red and made Red become a bad guy for no reason.
| Pikachu is Yellow's only known Pokémon. It has good surfing skills. Since Red also had one, he used it to his advantage to pretend to be Red.
