What Pokemon that have one or more major weakness that can be added another type still results in its major weaknesses?

For example, theroretically, if Scizor were to have Grass type in addition to its Bug/Steel typing, Scizor would still have it’s major weakness to Fire moves. What other Pokemon that have a major weakness or weaknesses that could have another type added to it would still have only one weakness? Please list the Pokemon and the type that could be added to their typing that still results in their major weakness.

Note: Major weakness: 4xFor the additional typing, if a Pokemon has a 4x weakness to something and a type gets added to make the weakness 2x, it does not count

Note: If there are multiple instances where multiple types will cause a 4x Weakness, I will just list all of them at once. Also. I will list these type combinations twice just for clarification for each Primary Type. Eg. Fire/Electric will be On Fire and Electric. If you don’t want this, I will edit it out. Also, this is for every type. There are some combinations that have no Pokémon.Fire/Electric- Poison, Rock or Steel for Ground.Fire/Ice- Flying and Bug for Rock.Fire/Ground- Rock for Water.Water/Ground- Rock for Grass.Electric/Poison- Rock and Steel for Ground.Grass/Ice- Bug and Steel for Fire.Grass/Fighting- Bug for Flying.Grass/Ground - Bug, Dragon, and Flying for Ice.Grass/Psychic- Dark for Bug.Ice/Steel- Grass and Bug for Fire.Ice/Normal- Rock, Dark and Steel for Fighting.Ice/Bug- Fire and Flying for Rock.Ice/Rock- Fairy for Steel.Fighting/Grass- Bug for Flying.Fighting/Dragon- Dark for Fairy.Poison/Fire- Steel, Electric, and Rock for Ground.Ground/Fire- Rock for Water.Ground/Water- Rock for Grass.Ground/Grass- Flying and Dragon for Ice.Flying/Grass- Ground and Dragon for Ice.Flying/Fire - Ice and Bug for Rock.Psychic/Bug- Dark for Bug.Bug/Grass- Steel and Ice for Fire.Bug/Grass- Fighting for Flying.Bug/Fire- Ice and Flying for Rock.Rock/Fire - Ground for Water.Rock/Water- Ground for Grass.Rock/Normal- Ice, Dark and Steel for Fighting.Rock/Fire- Electric, Poison and Steel for Ground.Rock/Ice- Fairy for Steel.Dragon/Grass- Ground and Flying for Ice.Dragon/Fighting- Dark for Fairy.Dark/Normal - Ice, Rock and Steel for Fighting.Dark/Grass- Psychic for Bug.Dark/Fighting- Dragon for Fairy.Steel/Grass- Bug and Ice for Fire.Steel/Normal- Ice, Rock and Dark for Fighting.Steel/Fire- Electric, Poison and Rock for Ground.Fairy/Ice- Rock for Steel.Normal/Dark- Ice, Rock and Steel for Fighting.Source:https://pokemondb.net/type/dualHope this helps!
