on my red version, i was against Lt. Surge and i forgot to pack a ground pokemon because i thought my ivysaur's resistance to electricity would suffise. it didn't and raichu took him out, other then him i had pidgeotto and butterfree, i think... anyways, i took my pidgeotto because he had quick attack and it was a complete failure, so i sent out butterfree and, just my luck, he used an X Speed on raichu and my confusion took him out in one hit.
