>>50995001The game gives you defensive options in the form of Wooper, Sandshrew, Geodude, and Onix regardless of your starter who all at least resist Rollout if not Stomp too and have passable physical bulk for the time you fight Whitney. Plus I'm pretty sure all of them can learn Mud Slap which hey look what TM you got two gyms earlier and fucks over Rollout even harder.
Then for offense you have Machop and Heracross, and I'm pretty sure you can also find Nidoran just to the north which can learn Double Kick. No STAB but it's something. People just lost to Whitney because they were dumb kids who didn't bother exploring the areas around Goldenrod before blitzing the Gym, and only used their Quilava.
