You should swap your party Pokemon with a friend and get them to level them up so it gets double the exp point. Also you could give it an exp share and take it to the Pokemon league, if it is too weak to fight then it doesnt have too but it still gets alot of EXP the average Pokemon will grow to level 32 if you take it through the Pokemon league with an EXP Share (I take it through with a level 100 Rayquaza so this may vary for other Pokemon).
The easiest way to level up is to feed Pokemon Rare candies.
the easiest way to level up your Pokemon to put it in daycare Pokemon will level up soon.Trade the Pokemon to friend and have it hold a lucky egg it will level up quickly.
It's mewtwo I have one he/her never dies but you have to level him up to your highest level to be the best I have a level 97 Pokemon that's way stronger than mewtwo he's level 80. It depends on level. If you are talking about lv100 it is mew as mew can learn any attack
A good place train is the route next to Undella town. You can put exp. share on a weaker Pokemon let a stronger Pokemon do all the work and you will level up quickly because the Pokemon there are usually about level 50-60. Another way is by using the daycare to level up fast by just using your bike or running to level up.
Arceus the alpha Pokemon, it created pokemonand its base stats is the highest over any other Pokemon, Its the best Pokemon on paper, but when you play with it its not the BEST Pokemon out there. If you level all Pokemon to level 100 then Arceus would be the best, at level 100 it learns the move jugment. Also, if you catch a high level Pokemon, like a level 70 lugia, then level it up to 100, it wont be as stroung as if you got a level 20 lugia and level it up to 100, this is because the Pokemon earn more stats when you train them and not as much in the wild. So its best to get slightly lower level Pokemon, not the highest. Now, the best Pokemon in Pokemon hh and ss. This is only the best one avaulable to catch, without cheats or trading. The best Pokemon is probobly Lugia.

there is only one good way to beat a pokemon league in any pokemon game. that is without cheating. for me the best way without buying anything or cheating is to train ur pokemon to level 65 and up. i got through with pokemon level 55 and up but it was harder.
Giving a Pokemon an experience share at a low level while other, stronger Pokemon fight will level up to a strong enough to level to fight well and train. You can also level them up faster by using Rare candies either by using cheat codes and/or action replays or saving up Rare candies found throughout the game. The best way to level up your Pokemon is to fight constantly although it is not the fastest way.
Level up your best Pokemon to at least level 60.
The best legit way to quickly level up your Pokemon is by using a lucky egg, which doubles a Pokemon's exp after a battle. Or just use rare candies derived from an action replay if you are okay with cheating.
You can get a level one hundred Pokemon in HeartGold the same way that you can get a Pokemon of that level in other games. You have to level them up until they reach it.
Well you can go back to an earlier route where weaker Pokemon are you can battle them and after a few battles you will level up not exactly the fastest way but it prevents your Pokemon from getting hurt, once your stronger defeat stronger wild Pokemon.
