That's impossible -.-'
Level them up.
level them up on your own and slowly
Because if you overlevel it, it will be too strong.
Pokemon can only go up to Lv100 plus there are no wild Pokemon that are Lv100 unless of course you use action replay.
yes mine is at lv100 =]
you just have to work REALLY REALLY hard.......you have to fight high lv Pokemon, and your Pokemon will eventually reack lv100. but that's the highest lv it goes up to.
level them up
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
Buy rare candies (they're expensive though) and use them on the pokemon you want. (Max level is 127.)
Well i've never played pokemon vortex but i'm pretty sure it's the same as any online pokemon rpg game so just get a bunch of rare candies once your pokemon reaches lv100 use the rare candies on them to level them up some more.
You can train the Pokemon until they reach level 100 (Which will take a long time) or you can hack the game for unlimited rare candies. Although using that method, the Pokemon's stats will be lower then if you leveled them up the legit way.
highest level for any Pokemon is only lv100
