What moves in Pokemon XD and Pokemon Colosseum work differently than the core series game?

Question

I know that using Thief doesn’t steal anything

Comments

Using Thief does steal the held item, just not permanently.

I'm pretty sure Thief and Covet are the only ones, unless you count Shadow moves for some reason.

Answer 1

Thief and Covet are, to the best of my knowledge, the only two moves with a different effect in Colosseum and XD. No other distinctions came up on any other move pages.

Thief (Bulbapedia)

In Pokémon Colosseum and Pokémon XD, when used by the opponent, Thief does not permanently steal items.

Covet (Bulbapedia)

In Pokémon Colosseum and XD, Covet does not permanently steal items.
