What unreleased Dream World abilities were changed after generation 5?

Question

There's the infamous generation 5 shadow tag Chandelure and Zapdos which had Lightning Rod. Weird how all the other birds kept their own though. Are there any others I don't know?

Answer 1

Zapdos and the Litwick line were the only Pokemon to have unreleased hidden abilities that were changed in Generation VI.

Scolipede's hidden ability in Gen V was Quick Feet, which was changed to Speed Boost in Gen VI. However, its hidden ability was released in Gen V so this doesn't really count.

As far as I am aware that is all the Pokemon who have had their abilities changed.
