I've noticed a glaring inconsistency between what people in the general UT threads are saying about Outrage and Fairy-type switch-ins, and what actually occurs in-game (at least, when playing on Battle Spot) regarding this interaction. I've seen most people stating that when a Fairy switches in on Outrage, the Outrage user will not be locked into the move--that instead, the move is canceled and the user can choose a different move or switch out on the next turn.
However, this has not been my experience on Battle Spot. I have, in fact, been locked into (non-Choiced) Outrage against a Fairy-type switch-in, with the move continuing until the user becomes confused, just as the move would work against a target who is not immune.
Sorry if this is old news; I searched the thread beforehand and didn't see it mentioned, and I haven't seen many people acknowledging this in general either.
