H eyx there! Letting you k ow I moved your thread to Other Pokémon Gamesx as that's a more appropriate place for it.
As for a moveset, thunderbolt is a great option, since Red has 3 Pokémon weak to Electric. Psychic is a must for good STAB, Blizzard might be a good choice if you can get it, since it's Hailing on Mt Silver, giving 100% accuracy.
That should mostly cover you. If you can tolerate getting it to level 100, Aura Sphere would destroy Snorlax.
