15. Zekrom
Starting with Zekrom, a Pokemon from the Black and White era, this guy's a real (electro) shocker.
14. Meganium
Who doesn't like a dinosaur wearing a flower? Oh, you're one of those Water types? Move along then.
13. Scizor
Best Bug type ever.
12. Arcanine
A fire-breathing dog that looks like a tiger, apparently. One of Pokemon's first Fire Stone evolution types.
11. Zapdos
The highest-ranking of Pokemon Red and Blue's original trio of legendary birds, Zapdos is Woody Woodpecker mixed with Big Bird … and some serious static electricity.
10. Diancie
A mythical rock/fairy type that premiered in last year's Pokemon the Movie: Diancie and the Cocoon of Destruction.
9. Snorlax
This rotund form tends to snooze through battles, but if he DOES wake up, beware of high-powered attacks. The closest the series gets to a mash-up with Studio Ghibli's Totoro!
8. Rapidash
A horse with a fire mane that evolves into a unicorn. Because, of course.
7. Pidgeot
The original Pokemon bird.
6. Celebi
One of the rarest of them all, Nintendo let players download this Psychic/Grass type for free back in 2013.
5. Charizard
Equipped with a fire tail that comes in handy as a super smasher, if not a marshmallow toaster.
4. Lucario
A fan favorite who made his debut in the fourth generation of the series. He has also been a staple of Super Smash Bros. since Brawl.
3. Bulbasaur
One of the best starter pocket monsters. Dig the leaf.
2. Mewtwo
A clone of Mew, this cutie became one of the most powerful in the first wave of the series. Look for an appearance in Super Smash Bros. for Wii U.
