Recruiting Legendaries
~ALL ABOUT RECRUITING LEGENDARY POKEMON~
If you need to recruit a legendary Pokemon, first you must check your team's size. To do this, go to your menu and select 'Team'. From there, look at each team member's Summary and press the right arrow button two times. You will see a bit of information, which includes Size. The number of stars next to Size indicates, well, the Pokemon's size. If there is one star the size wil be one, and so on. Anyway, when going into any dungeon, the maximum size is six and the max number of members is three.
Most legendary Pokemon are not size 1. They're pretty big, ranging from 2 to 5.
Zapdos is size 4.
Articuno is size 4.
Moltres is size 4.
Latios is size 2.
Latias is size 1.
*Those are all I have so far*
Also, you cannot recruit Legendaries until you beat the main storyline (destroying the falling star and beating Rayquaza.
I suggest leveling up quite a bit before attempting to recruit a Legendary. They get more powerful and tougher to beat the second time you battle them.
Finally, never go on a rescue mission at the same time as recruiting a legendary. Let's say you were going to get Groudon and you had to rescue somone on 8BF. You do a good job at rescuing them, and continue on your way. Then suddenly, after you clear the final floor before entering Magama Cavern Pit, you "clear the dungeon". I don't know why you stop there (although it probably has to do with the saving), but it is really frustrating, having to go through all those floors again. Especially if you're in a place like the Sky Tower.
~I hope this helped~
P.S Sorry about only having the size listing for a few Pokemon. I haven't gotten that many legendaries yet :P
