In older gens, what type combinations led to no weaknesses?

For example, in gen 1 ghost psychic would have no weaknesses, are there any more?

•Dark/Ghosthad no weaknesses until XY, when Fairy was introduced.• As Sep said, a theoreticalNormal/Ghosttype would have had no weaknesses until Gold/Silver, when Dark was introduced.• As of Sun/Moon the only Pokémon tonaturally have no weaknessesare Tynamo, Eelektrik, and Eelektross, but this is due to an ability so it only partially counts.

That’s it, from what I can tell. Psychicdidactually have a weakness in Gen 1, Bug, but Bug was pathetic in Gen 1 so it effectively had no weaknesses.

As Mega_Sceptile mentioned, though no Pokemon with the Normal/Ghost-typing exists, that Typing would’ve had no weaknesses in Gen 1. Technically this can also be said for Water/Dragon, as in Gen 1, the only Dragon-type Move was Dragon Rage, which does fixed damage.

And as Squaaaaaaaaw mentioned, through Gens 2-5, Dark/Ghost had no weaknesses as well, and let to the lovely Wonder Guard Sableye & Spiritomb. (Fun fact: In Gen 4, Fire Fang could still hit anything with Wonder Guard like normal.)

Those are the only exceptions as far as I know, but if not, feel free to tell me. :V
