Have there been any other cases of abilities changing in the mainline Pokémon games?

For example: Chandelure was planned to haveShadow Tagas its HA in Black & White, but then was quickly changed toInfiltratorafter realizing it would be way broken. The Empoleon line also changed from Defiant to Competitive in Gen 9. Are there any other cases of abilities being changed throughout development / the mainline games?

In chronological order:

In BW, wild Basculin of both colors mistakenly had Reckless, in B2W2, this was changed so that Blue Striped Basculin’s first ability slot was Rock Head. However, a Blue Striped Basculin obtained from an in-game trade in White has Rock Head, making this the only case to my knowledge of a Pokemon being able to have four different abilities in the same game.

From Gen V to Gen VI, some Pokemon’s Hidden Abilities were changed:

Zapdos:Lightning Rod–>StaticVenipede line:Quick Feet–>Speed BoostLitwick line:Shadow Tag–>Infiltrator

From Gen VI to Gen VII, another group of Abilities were changed:

Gengar:Levitate–>Cursed BodyRaikou:Volt Absorb–>Inner FocusEntei:Flash Fire–>Inner FocusSuicune:Water Absorb–>Inner Focus

Several Hisuian Pokemon’s abilities were changed from PLA to Gen IX, despite abilities not being usable in PLA:

H Typhlosion:Flash Fire–>FriskH Samurott:Shell Armor–>SharpnessH Decidueye:Long Reach–>ScrappyH Sliggoo line:Overcoat–>Shell ArmorH Sneasel:Poison Touch–>PickpocketH Growlithe line:Justified–>Rock HeadH Braviary:Defiant–>Tinted LensKleavor:Steadfast–>SharpnessBasculegion:Rattled–>Swift SwimEnamorus:Healer–>Contrary

With the release of The Teal Mask DLC in SV, two more Pokemon have changed their abilities:

Shiftry line:Early Bird–>Wind RiderEmpoleon line:Defiant–>Competitive

An extensive list of Pokemon have gained new abilities from game to game; you can see that listhereif you’re interested.

Hope I could help!
