There's lots to do...
Beat Elite Four.
***All this other stuff requires you to beat the Elite Four to do***
Catch swarm Pokemon (talk to Dawn's sister at her house in Sandgem town).
Swarms happen every day, each is a random Pokemon exclusive to Pearl.
Pokeradar Pokemon (Go back to Prof. Rowan's lab and receive from him).
Use the pokeradar in a patch of grass and walk into a shimmering spot. Keep defeating the same species over again and usually an uncommon Pokemon will appear in a patch of grass.
Go to the trophy garden south of Hearthome talk to owner and he will tell you a rare Pokemon is in his garden. (Random Pokemon each day).
Beat Stark Mountain and Catch Heatran.
Go back to Canalve City and Talk to the sailor's sick son, then talk to the sailor who runs the boat and go to Fullmoon island, get feather and see Cresselia, go back to boy to cure him. Cresselia will now appear at random times in a wild battle.
Battle Tower: Win Battle Points earn TMs and Items.
Pal Park: (Unsure as to whether Beating the Elite Four is required)
You talk to Professor Oak and he'll give you the HM 08, Rock Climb. Then he'll unlock the way to Mt. Silver. To fully beat the game, you'll have to get through Mt. Silver and get to the Mt. Silver Peak. Once you are there, you'll see Red, the former Elite 4 Champion. You'll battle him. Beat him and you will have beaten Heart Gold or Soul Silver. Congrats! YOU BEAT THE GAME!
After you beat the 8 gym leaders in Pokemon Black, you have to go up north and through victory road. I don't remember the city of the 8th gym leader, but it's in that city and go north from there.
Once you acquire 8 badges, it's time to take on the Pokemon League challenge. Head East from Mossdeep City to find Victory Road, which leads to the Pokemon League HQ.
You can go catch Mesprit, Azelf, and/or Uxie, and then go to the Pokemon League, north of Sunyshore City.
well you have to get all 16 badges. 8 johto, and 8 kanto. Then go talk to professer oak in pallet town. He'll give you permission to go to mt silver.
I've never been asked that sort of question but I don't think you can ask them. You will battle all (all five) of them and then the bell tower rings and you must get to the top to see the one and only Ho-Oh. You are allowed to capture it!
Get all the items to get in the bell tower with the kimono girls, they will do a dance, and then he comes.you have climb to the top of bell tower in ecuteak cityWith the Rainbow Wing, climb Bell Tower. Ho-Oh is at the top and will be at level 45 in HG and level 70 if you're playing SS.
In Heart Gold and Soul Silver, you first go to Johto. After you defeat All 8 gym leaders, you have to go to Kanto. At the very right of New Bark Town, you will see a lake. Use Surf and you will be at Kanto. Then you have to defeat the Elite 4.
Fight the remaining 8 gym leaders.
8
You are in jhoto first then when you have all the 8 gym badges you can go to kanto and get 8 more badges which will be all 16 badges then you can challenge the pokemon league. Hope that helped.
we can get 8 gym badges byfighting all the gym leaders in Pokemon pearl.
you get all 8 gym badges
No, you can trade with no badges at all.
8!
you have to have 8 badges first
There is only 8.
there are 8 badges in Pokemon ruby like all the others. :) tehehe
you have to have all 8 gym badges
Yes, it will obey once you get more badges. After getting all 8 badges, all Pokemon will obey regardless of level. Do note, though, that getting certain Pokemon such as Deoxys by the use of a cheating device can cause them to disobey you even if you have all 8 badges.
You need to beat all the 8 gym badges. I have just completed the 8 badges and my Pokemon are all around lv. 65 (well... at least 3 of them are!). I hope this helps
