3. Pikachu
This little yellow electrical pokemon is a cross between a rabbit and a guinea pig and has a tail in the shape of a lightning bolt. It is a stubborn little pokemon but amazingly cute and fierce none the less. It is always there to help you out of a bind and is faithful to the end. It will fight until it just can't fight anymore to keep Ash happy and safe and will always do his best. Although it may not look like a lean, mean, killing machine in this picture, do not underestimate its ability to send a few thousand volts in the direction of the enemy. Unlike other pets if you don't want him around for a while your can keep him in his pokeball until he is needed, although, he is not a big fan of this and it may be a bit of a mission to get him inside.
