Just use type match up, I beat Pokemon 20 Levels higher like that.
If by strong you mean higher level, the stronger trainer is your rival, which you can battle at the weekends at the Fight Area.
You have to level up your pokemon a lot and make them stronger.
fight the elite four
When you finally manage to fight him, his Pokemon will be levels 75 to level 77. But after beating the elite for twice to get to him you should be fine.
Yes. If yu beat them 1ce, they get Level 65-80 strong
How to beat the elite 4 is easy, first get your Pokemon to a high level and then fight them. Avvenchully your Pokemon will get to level 100. Then it will be a peace of cake
To up your Pokemon's to 100lv you have to fight the elite 4 100 time ......
Fight oher pokemon or get an ar code for rare candies give an exp share to your pokemon then go and fight the elite 4 a few times or untill desired level
U will fight him at the end of meteor falls after the elite 4.Be carful though,his Pokemon are above level 70
After you beat the elite 4 you can battle wally at the end of victory road after you beat him exit then enter and his Pokemon will be stronger
Give it exp share go to the elite four with strong Pokemon and pikachu fight the elite four with your strong Pokemon only, pikachu will level up at least 10 or more times when you finish.
yes they do get stronger after i beat the Pokemon league the first and went back the second time they were like 10 or more levels stronger at the start of Aarons battle his yanmega is level 65
