>>27675640Twineedle is a Beedrill exclusive. Beedrill is a horrible Pokemon that's weak to Psychic.
Pin Missile had 14 base power. On an average of 3 hits that's a less-than respectable 42 base power, times 4 is a decent 168 base power...But only Beedrill and Jolteon learn it. Jolteon has low Atk but could admittedly make use of Pin Missile to take out Grass-types.
Still, the point was that gen I had almost no bug moves worth using. Jolteon's (very) niche use of Pin Missile does not change that, and its low base power combined with Jolteon's low attack hardly lets you 'sweep'.
