Best knockoff users?

Question

I have Pokemon diamond, heart gold, black and omega ruby, and I want to know if there is an amazing knockoff user I can catch in any of those games.

Answer 1

I'm going to have to disagree with Luna

As Weavile is pretty great and all, it's really frail leaving it open to faster priority moves. Or really, anything faster than it.

Good abuser #1 - Azumarill

With its great bulk, it can easily take an unboosted priority and return with a Knock Off. Even access to Belly Drum and Aqua Jet makes this thing a great choice!
Azumarill @ Sitrus Berry
Ability: Huge Power
EVs: 132 HP / 252 Atk / 124 Spe
Adamant Nature
- Belly Drum
- Aqua Jet
- Play Rough
- Knock Off
This is the standard BD Smogon set. I tweaked the EVs a little bit to make it slightly bulkier.

Good abuser #2 - Scrafty

Pretty good bulk and OK attack allowing it to survive many a hit if you plan on using a bulky variant. Just watch out for birdspam. Dragon Dance + Knock Off makes this thing a beast at +2 or more!
Scrafty @ Leftovers
Ability: Moxie/Intimidate
EVs: 196 Atk/188 Spd/100 Hp/24 Def
Adamant/Jolly Nature
-Dragon Dance
-Knock Off
-Drain Punch/High Jump Kick
-Ice Punch
This EV spread gives it average bulk most of the time allowing it to get a DD off. Intimidate provides more bulk while Moxie is for straight up sweepers.

Good abuser #3 - Mew

Ever thought this can ruin your day? No? THINK AGAIN BUD. Will-O-Wisp and Knock Off along with Recover makes for a perfect tank (almost) only struggling against anything with a +1 STAB move if you run no defense investment.
As for a set for this, as far as I'm concerned, way too many to pick out a good one.
Hope this helps!

I do have azumarill in diamond and I can catch scraggy, but I have no possible way to obtain mew.  I'm looking for pokes i can catch in game, not Pokemon showdown picks. Thanks for the suggestions!

Huh... I didn't know Azumarill could learn Knock Off :) you're right on it being better, but Azumarill almost never runs Knock Off (at least from what I've seen)

Answer 2

This is the best Knock off user (imo)
Weavile

With its dark typing and amazing Attack/Speed, Knock off is going to hit hard while also rendering Pokemon who rely on their items such as Eviolite Chansey useless. Add a Life Orb and it'll hit even harder.

Weavile@Life Orb/Focus Sash
Nature: Jolly/Adamant
Moveset:
Ice Shard
Knock Off
Fake Out/Swords Dance
Brick Break/Night Slash

You can find Sneasel in HeartGold in Mt. Silver, the Giant Chasm in Black, and I believe the route near Snow point City on Diamond. You will need a Razor Claw in order to evolve the Sneasel though.

Hope I helped!

Weavile is one of my favorite pokemon, so cool! I have both a sneasel and weavile on my diamond version, thanks!

No problem.  I even added in a Moveset you can use :) remember: Knock Off is a move tutorial move. You can teach it to Weavile in Omega Ruby
