What do you do after you beat all the gym leaders on Pokemon platinum?

Answer 1

if you have beaten all the gym leaders in johto, you have to go on and beat the kanto leaders to.

But, If u have all 16 badges, go to the silver cave in johto and battle a guy named Red. he is really strong. I think he has Pikachu lvl80, venusaur, charizard, and blastoise lvl seventy something. that is all i remember of his Pokemon but there hard.

Answer 2

go to the TEAM GIGLATIC building in vilestone city and battle all the people inside.then,go get Diagla.the way you get diagla is go into mount cornet(2nd time)from route 207,then go up then turn right and surf on the water.then use rock climb to go up the rocky place.thengo into the door.now you have to go to thedoor at theN&Wcorner.then when you got to 3fl,go around it then exit the door.now you should be in a snowy area,goto theN&Wdoor ,then use rock climb,exit the door ontheN&Ecorner.once you got out,the snowy area appered again,go down the stair way,use rock climb on the right rocky place ,keep going on the stair way until yoiu see a door.thengo to the stair way,and another.then go toa dooron the N corner.thenyou got to the diagla place.use fire type or grass type to lower his HP down,thenwhen you make it one HP,make it sleep,then use an ultra ball. I wish that works for you!
Go to Lake Acuity and stop Commander Jupiter. After much talking,( you dont have to battle her), she will warn you not to enter Team Galactic's HQ. Do that. It's in Veilstone City. After defeating Cyrus at the very end( and receiving the Master Ball!!), you will have to defeat Saturn again(no big deal) and free Mesprit, Uxie and Azelf. After that, proceed to the peak of MT. Coronet(via the path in the northern part of the cave outside of the west side of Hearthome City. I recommend you stock up on at least 20 Dusk Balls and 20 Ultra Balls. You will have to catch or battle Dialga soon. DO NOT USE YOUR MASTER BALL ON DIALGA!!!! I caught him after using 3 Ultraballs and a Duskball. Patience.

Answer 3

This applies throughout the rest of the game too, but if you can’t move forward after beating a gym leader, it means there’s something else for you to do at a place you’ve already been to (even if it’s just using an HM move), so turn back around and look for what you’re supposed to do next.
