What do these Pokemon have in common?

[Tomokazu Komiya]

Let's start a new game. People will list a bunch of Pokemon, then everyone else will try to guess what they all have in common. So here's the rules.
1.) No one can ask a new question until the last one has been answered. If you want to post, it has to be a guess.
2.) The person who posted the answer gets to start the next question. Winner rules!
3.) No dumb answers like "All basic Pokemon" or "All have a card in modified play". If we wanted to put groups like that, there would be over 100 Pokemon on the list. So those answers are DUMB.
So I'll start!!! What do thse Pokemon have in common?
Aerodactyl
Sableye
Zapdos
Tyranitar
Kingdra
Girafarig
Heracross
Breloom
Steelix
Gligar
Magcargo

[Tomokazu Komiya]

Yes, that's true, but it's a bit more complicated than that....

 

[Heavenly Spoon]

they all have something to do with (F) (weakness, type, resistance)

 

[Tomokazu Komiya]

Nope. if you don't get it right one more time, I'll just tell you.

 

[Heavenly Spoon]

[Tomokazu Komiya]

Nope. They're all the only Pokemon of that type combination. Bug/Fighting? Only Heracross. Dark/Ghost? Only Sableye. Now, you post one.
