How is Ash's Pikachu different from any other Pikachu?

It refuses to evolve, which can normally be done by the use of a Thunderstone. This trait was carried into Pokemon Yellow, in which you can't evolve your starter Pikachu (though you can evolve another Pikachu if you get one, or trade the starter Pikachu to another game and trade it back).
