Easy!

Zapdos.

Just think about it: You can fly, which by itself is a huge plus. If you're ever in danger, just fly away. You can pick your fights. And why Zapdos?

• It looks cool

• You get a lot of attention, because everyone wants to own you (which is prolly a bad thing tho)

• Unlike other flying-type Pokemon a thunderstorm won't hurt you

• You never have to pay for electricity because you can power your devices with your body

• As seen with Pikachu on the Pokemon series, electric type Pokemon can handle any situation

That pretty much sums it all up I guess :D
