It's pokemon Pikachu, but instead of pandering with just one pokemon, you could put your bro in there and hang with your bro.
Also:
Mystery gift back to its former glory
Exclusive berries
Pokemon that couldn't be caught at early stages in the game but are still good (doduo, the baby pokemon, they're all good)
Special pokemon like surfing Pikachu and flying Pikachu.
I really wish the 3DS had a low power mode so you could do that, it would be so great. You could even tie it into street passes and bring mystery gift back
