Is there any special attack that can OHKO Blissey?

Aside from Psyshock, Blissey being 252 Hp, 252 SpD.

But I believe that even Pyshock and Psystrike don’t OHKO Blissey.commented 3 minutes ago by Crimson1

You’re wrong.

252+ SpA Keldeo Secret Sword vs. 252 HP / 4 Def Blissey: 1256-1478 (175.9 - 207%) – guaranteed OHKO

Same case as Keldeo’s Secret Sword

The closest you will getWITHOUT ANY DROPS OR INCREASES IN SPECIAL ATTACK OR DEFENSEis probably this;>252+ SpA Choice Specs Kyogre Water Spout (150 BP) vs. 252 HP / 252+ SpD Blissey in Rain on a critical hit: 589-694 (82.4 - 97.1%) – 62.5% chance to OHKO after Stealth Rock

Yes Specs Kyogre in Rain is stronger than Specs Kyurem-W

However do remember, once you factor in boosts and drops, many special attacks can kill Blissey. For example;>+6 252 SpA Gengar Sludge Bomb vs. -6 252 HP / 252+ SpD Blissey: 1371-1614 (192 - 226%) – guaranteed OHKO

Psystrike and Sacred Sword are other alternatives to slay blissey with a Special move but other than those and Psyshock,almost no special attack slays Blissey without any status drops.

Why, a fully invested Kyurem-W can’t take out a Blissey with Specs-Boosted Draco Meteor on Critical hit. With Special Defense drops though, it is possible to defeat Blissey with a Special Attack.
