Machamp
Your starter
A gengar with dark type moves
Pidgeot of however you spell that
Alakazam
and Dragonite
you should use water types because they are strong against fire types
level 55 and up and ever type of Pokemon

The elite four will be in the Pokemon league.
Gary is or what ever you named your rival. He will have the Pokemon that is the strongest against your starter. Hope this helped!

In order to beat the Elite Four in Pokemon FireRed, you need to have six Pokemon that are extremely strong, and they should know good moves. Train your Pokemon so there ready for battle. You need to stock up on medicines, and then head inside! Good Luck!
your strongest Pokemon

Yes. First you have to beat the Elite Four in both games, then do the stuff for Bill in FireRed
