They're at their strongest. You can still change that Pokemon's moves, but when you fight with it, it won't gain EXP.
hmm that a tough one... i think its level 100! wad ya think happens?!?
they are as strong as they can be
It does not gain any more EXP points and has max happiness unless it was caught at level 100. Nothing special.
Nothing trust me I have over 50 level 100's in my firered.
it stops growing levels. therefore it is the highest it will get
It stops leveling up. Lv 100 is the maximum lv.
I recommend a level 100 lugia or ho-oh,a level 100 raiko,a level 100 arceus ,level 100 of any of the starters,level 100 scizor, and a level 100 of any Pokemon you choose
You can't catch Level 100 Pokemon in any Pokemon game. The highest catching Level in Pokemon is Level 80. You need to raise your Pokemon to Level 100 or trade for a Level 100 Pokemon to get one. You can also challenge Level 100 Pokemon, but only in the organized challenges of the Pokemon games (i.e. Battle Tower, Trainer Tower).
you have to battle against other Pokemon that are level 100
No you can not get Pokemon higher than level 100.
There's no room that has level 100 Pokemon.
There is no level 500 Pokemon. The highest level that a Pokemon can be is level 100.
