Pokémon LeafGreen/FireRed

The Blastoise would ideally be a female with a mild nature (gains special attack at the sacrifice of defense), however I settled for a rash nature (gains special attack at the sacrifice of special defense). This is potentially only problematic fighting Surge's Raichu, the rival's starter, and the occasional trainer's bellsprout early in the run. Surge was offset in the SS run by postponing him until after entering Celedon City, at a total expense of around 30 seconds lost. The final moveset was Brick Break, Blizzard, Surf, and Bite.

Torrent Sweep: Squirtle's pokemon ability is "Torrent," which boosts water moves by 1.5 when HP is at or below 1/3. By purposely keeping Squirtle's HP as low as possible, utilizing torrent to KO enemies in less turns than usual. A good example of this are the pokes on the way to Mt Moon, where I OHKOed the bugs instead of taking 2 hits each.
