Its best if you have 1 fire Pokemon and 1 ground Pokemon.
See question "Is this a good team to beat the elite four"'s answer.
Nothing. Don't waste your time.
He will be at his house, if you didn't go to the islands yet he will be in the cinnibar island Pokemon center.
nothing really, you can keep fighting them
use good Pokemon that's the only way
against the elite four infernape will do very good with its fire type moves but since the first gym is ground it is not so easy to beat it with a fire type. i beat the elite four 6 times with my infernape. the beat moves for it are fire blast and flame wheel
you only have to beat the elite 4 on Pokemon fire red not ruby
Fire and water are the best combination to beat the elite 4.
One island.
The same you can do in Fire Red.Read my answer to that here:What_can_you_do_after_you_beat_the_elite_four_in_pokemon_fire_red
There is no easy way to beat the Elite Four. You have to level up your Pokemon and use the right types of Pokemon against each of the elite four (i.e. don't use a fire-type Pokemon against water-type. Use electric instead). I recommend level 60 or so for the Elites. Good luck!
You have to migrate them, which I think can only be done when you beat the elite four.
Its best if you have 1 fire Pokemon and 1 ground Pokemon.
The only way I know is in Pokemon fire red and leaf green,you have to go into seafoam island.You don't have to beat he elite four,you just go in.
