you have to buy southern island from wigglytuff's friend area shop and then the next early morning you should get a mission from the kelecon brothers and then you gain access to northern range
Buy the Southern Island Friend Area from Wigglytuff. The next early morning, the Kecleon brothers should send you on a mission to Northern Range. After that, you'll gain access to Southern Valley.
There are 25 floors
Latios : northern range latias: pitfall valley
On mystery dungeon in northern range, there is 25 floors and that's when you meet latios.=)
You get it when a Latios steals from the Kecleon Shop so that you can investigate it.
when u wake up one morning a big blue blur flies by in the front of your rescue team base. u go to Pokemon square and kecleons say they got robbed. then u and ur partner decide u and him/her should go get the criminal. then that's when u gain access to northern range. go there, and at the end u beat latios. when u beat him, he passes out and u take him back to the town. he revives, and then he explains that he stole items to help his beloved sister, latias. and then u and ur partner gains access to pitfall valley, where latias is trapped at.
Latios is in the Northern Range and Latias is in Pitfall Valley.
If you've beaten Rayquaza and bought the Southern Island Friend Area, one early morning, Latios should zoom by your house, unlocking Northern Range. After beating Latios there, you unlock Southern Valley, where you rescue Latias. Then, both Pokemon join your team.
latios is in the northern range :D. hope i helped!
Northern Range, which opens after you unlock HM Surf from Solar Cave 15F and buy the Friend Area Southern Island, is a 25F dungeon with the boss Latios. The only recruitable Pokemon in Northern Range are Hoothoot, Spinarak, and Seviper.
there isn't one.but, if you complete solar cave, and have the friend area southern island, you can get the mission to conquer the northern range and get latios and latias.you have to do the northern range and pittfall valley,which youu do after the northern range to get them,but they want to join your team automatically. hope i helped!=)
