>>46401616Mt Mortar 2F has level 30 - 33 Machoke, Graveler, Geodude and a few others. In comparison, Clair has level 38 & 41 mons, the legendaries are 45 first time, the highest level mons in Victory Road are 36, (your rival, lvl 40), and Lance's highest lvl pokemon is 50. Mind you that's the only pokemon in the e4 that's above 50 in the first time you go to become champion. Then, by the time you're done & off to Mt Silver, the strongest pokemon besides Moltres is lvl 51, and Red's team consists of pokemon from lvl 80 to 88.
So basically, if you just even switch out one of your pokemon for another to train up, you're going to be there for quite some time.
