quote MamoswineLucario
When u rematch the 16 gym leaders do they:
1. Pokemon change or do they always have the same ones?
2. Do they increase their level for example does falkner always stay at that low level?
3. How many times can u actually rematch them?
Their teams change for the first rematch, but the teams stays the same after that.
Same for the levels.
Infinitely.
