lol you get Zapdos and all the rest by only having 2 pokemon w/ you(you and you're teammate) and sometimes they'll ask you, sometimes they won't(i got Zapdos the first time I refought him for the second time, but Moltres i've fought a couple times now and haven't gotten him). Sometimes you get them, sometimes you dont, it's just like trying to recruit normal pokemon. When you only have 2 pokemon and you fight them WITHOUT their friend area, you automatically get it.
The Gang is all here and ready to kick @$$!!!
