What To Do After Beat Pokemon League In Pokemon Platinum?

Finish your pokedex, then go to professor rowen's lab in Sand gem town, have him upgrade your pokedex, go to Snowpoint City, go to the boat should take you straight to the Battle Frontier, go up from where your standing, talk to fisherman, he gives you the super rod, keep going up, then you should be running into new pokemon.

Fly to Snowpoint city and go to the man with the boat he will take you to fight area.

You get on a boat at snowpoint city to the battle zone

Try to look and maybe capture all the kinds of Pokemon in sinnoh to get your national dex. That will unlock much More features, then after that try and complete the national dex. It's easy to do if you've battled all the trainers.

P.S. You don't need to catch all the Sinnoh pokemon to get the national dex, just see them.

Go to the boat at snowpoint and then go to  battle frontier youl see two people talk to them and your rival will apear youl be in a tag battle you and your rival must face to of the elite four beat them and go inside and you will be allowed inside but you don't have to go then complete your pokedex and go to Prefessor Rowon and youl be able to go to stark mountain and be able to get heatron but use a great ball or a master ball no other ball will work

The two orbs for dialga and palkia are in the cave with the waterfall on the way to spear pillar in two different pokeballs use waterfall and go in another cave then there they are there is another item on the rock hooray you can now get dialga and palkia AFTER heatran

Hmmmmmm the best thing you can do if not restarting is to a) fill your pokedex b) battle friends c) just mess around d) go to the resort  e) walk like 300000 steps to get some thing (I think its a chandelier)  :) p.s. Don't cheat it makes the game so less enjoyable

Go to the resort area

Trade the game in at game stop

You can level up your pokemon to the max

Go to the hall of fame

Go  to battle zone and find ways to get hard pokemon to get that what I did

If you have and beat pokemon ranger enter some code (search online because I'm to lazy) to unloke a special quest and when you beat it (its easy) its called like rescue special egg or somtin any ways onec you beat it you can go to the game and check egg press send and like got to a friends house or somtin use his ds so you have 2 put platinum I the sec ond one turn it on and itel say somtin like resiving signal and you get a manphy egg and if you find a dito (you can get when pokemasoin has it in it)breed them and you get a pokemon calld phonie have fun phonies is like baby manphy

Well, you could get arceus event or action replay, get griseous orb ( turnback cave distortion world) and get everything in your villa thats what I did

The only problem is if you have a dsi. Personaly I don't want to buy o ds or gameboy.

Get the national pokedex the migrate after that wait for a nintendo event to get arcues, shaming, or darkari or get a action replay oh I almost forgot get dialga and the other one of there orbs talk to old lady in the place where the gramma of the leader is the leader I mean as the one from the pokemon leage the go get palkia and dialga in the mt.coronet

Buy another game and be happy. Thats what I do.

Battle the elite four, their levels change

Get all the pokemon or just use a action replay to get all of the in the pokedex ps you don't get the they are just in your pokedex

Train, fill up pokedex, find all the hidden items, find glitches, put your pokemon in order eg, water in one box and grass in another. And if you get board, battle people on wifi. That what I'm going to do

I went to fight area battle hall is my favourite out of the battle frontier btw

Justt fill your pokedex and train it's fun to battle online and just go to the battle frontier and finish that and well hm capture all the legendarys and wait for events that's pretty much it

Well since theres two people blocking the way just get`the pokedex
