It was bad back in Generation Two, but all the new changes since then has made it... still really bad. Why anybody would care about a moveset for this guy is beyond me, nobody should even think about using him. Anyways, mine has the ability Vital Spirit which is good considering that Hustle is in my opinion the worst ability in the game (maybe along with Truant and Slow Start.) My Delibird is fairly equal in Sp. Attack and Attack. It knows:
Focus Punch: High power, high accuracy, deals with Steel and Rock types.
Water Pulse: Decent power, decent chance to confuse, high accuracy, deals with Fire and Rock types.
Ice Beam: Good power, high accuracy, STAB, chance to freeze.
Toxic: Inflicts toxic poison. Might as well get some use out of Delibird.
Seriously, why are you spending time on this one? Or you're trying to insult someone by actually using this thing?
