Right now, not facing Red cuz my highest at the point i beat Blue was like... 53 or something. So I decided to go after the Elite Four (also after I got Mew) to level them up and beat the E4 once more.

So far It':

Aerodactyl
Blastoise
Garchomp
Jolteon
Mew
Typhlosion

The lowest at 54 and the highest at 56. Still can't get past Bruno, but EXP is EXP until I can beat Red... which will be a miracle in and of itself whenever I get around to it.
