Level up all your Pokemon so they're all at least level forty five, preferably higher. Sceptile should be closer to sixty by default, since it's your starter Pokemon. Also, make sure you have a balanced team, and at least one Pokemon that knows Ice Beam to take care of any dragon types.
Good luck!
Sceptile
you only have to beat the elite 4 on Pokemon fire red not ruby
The Pokemon League
You need an electric type or ice type may i suggest glalie, manectric or walrein.
a swampert, lombre, or sceptile. if you don't have one then use a water or grass type
If you are referring to the old GBA games, then yes and no. You have to beat the Pokemon League in Ruby and Sapphire to get Rayquaza but in Emerald you can get him before beating the Pokemon League. Hope this helped.
Sceptile doesn't evolve. It's already the final stage of evolution.
Beat the Pokemon league, then go to Pal Park. You must have a Pokemon that knows Surf.
swampert or blaziken are the best type to beat gyms or Pokemon league
Well if you ment GRASS Pokemon in ruby the best is the first one you can get from proffesser Oak, trecko, who evolves to groovyle on lvl. 15-16 and then sceptile on lvl. 36. Sceptile is far the srtongest grass typer Pokemon EVER!!! (in ruby)
You don't talk to anyone, you just beat the Pokemon League.
yes . raquazas location does not open itself until after you beat the Pokemon league
