This is Honchkrow's flagship set, striking fear into the hearts of every player and threatening offense and stall alike. Once Honchkrow can get a kill or two, it becomes almost impossible to stop as it can destroy every Pokemon that doesn't resist Brave Bird, kill all fast offensive Pokemon with Sucker Punch, and obliterate all Rock- and Steel-types with Superpower. If you can open up a spot on your team to fit Honchkrow, its downfall will be by its own hand most of the time, as opposed to your opponent's. Honchkrow hits brutally hard, and you can't allow it to kill anything on your team, as otherwise, you'll fall prey to the mighty bird. Brave Bird and Sucker Punch are the two main moves on the set, making use of Honchkrow's semi-unique STAB combination. Generally speaking, Brave Bird finds more use against slower opponents, as they tend to be bulkier, while Sucker Punch finds more use against faster ones. Brave Bird is capable of 2HKOing almost all physical walls in UU that don't resist it, with Gligar being the rare exception. Sucker Punch is also a very good move for Honchkrow, as it can KO most faster threats with the move before they can hit, especially the numerous fast Psychic- and Ghost-types in UU such as Azelf and Mismagius.
While Brave Bird and Sucker Punch form the core threat of Moxie Honchkrow, Superpower is a fancy toy that is very beneficial as well. What would seem to be solid counters to Honchkrow, such as Empoleon, Rhyperior, Registeel, and Bronzong, are all hit hard by Superpower, leaving them unable to stop Honchkrow's sweep. Superpower is also useful against Snorlax and Porygon2, with the former causing Honchkrow to take ridiculous amounts of recoil if using Brave Bird, and the latter boasting extremely high Defense due to Eviolite. However, Heat Wave is another long-lost friend for Honchkrow, and can be used as well, most notably hitting threats such as Cobalion, Escavalier, and Ferroseed harder. It's generally not necessary though, as the latter two are hit hard by Brave Bird anyway, and Cobalion outspeeds Honchkrow and takes little from Sucker Punch.
Instead of Heat Wave, Roost is the preferred option in the last slot. While it will rarely be of use, it is wonderful for healing off the damage taken from Life Orb and Brave Bird, and no other move is generally needed anyway. It is best used when your opponent tries to play around Sucker Punch and tries to lure Brave Bird, but with Roost you can stay one step ahead. Substitute is a good move in Honchkrow's repertoire that works well in conjunction with Roost, as it is good for avoiding status and decreasing Honchkrow's reliance on Sucker Punch. However, Substitute can also be used with Heat Wave to break walls effectively. Heat Wave is the better option in tandem with Substitute because Superpower makes Honchkrow's sweep harder to attain in a shorter period of time, and also makes Honchkrow's already frail Substitutes easier to break. Pursuit is another good option in the last slot as an easy way to get Honchkrow's sweep started, as Honchkrow can trap a weakened Xatu or Slowbro to get its first Attack boost, and then it will be all downhill for your opponent from there. However, if you don't use Roost, then Honchkrow's sweep will often be cut short by Life Orb and Brave Bird recoil.
Maximum investment in Attack and Speed is the optimal EV distribution if you're not using Heat Wave; Honchkrow is most effective when it's as fast as possible while hitting as hard as possible. Note that only 196 Speed EVs are needed to outspeed uninvested base 95 Speed Pokemon such as Xatu and Arcanine, but maximum Speed is better as the remaining EVs wouldn't add much bulk, and that way you can avoid the Speed creep with Xatu and Arcanine as well as opposing Honchkrow. However, if using Heat Wave, feel free to subtract EVs from Speed and Special to leave about 60 EVs to be placed in Special Attack, slightly increasing the power of Heat Wave. Life Orb is the preferred item on the set and provides a sizable boost to all of Honchkrow's moves. The added recoil generally isn't an issue thanks to Roost, which makes it an absolute necessity if not using Substitute. If you are going to use Substitute, though, Leftovers is an option to reduce the damage taken from Substitute, Brave Bird, and possibly Stealth Rock. It helps with this problem to some degree, but not enough to drastically enhance the set's performance.
Needless to say, Honchkrow has some other moves that it can use on the set from its wide movepool. Taunt is the first thing that can be of some use, and like Substitute, protects Honchkrow from status. It works especially well in combination with Sucker Punch, as it forces the opponent to attack, making the move unavoidable except by switching. However, the health lost in order to create Substitutes can be easily replenished by using Roost, and Substitute allows Honchkrow to shield itself against revenge killers that can take a Sucker Punch, such as Cobalion. Night Slash is another good option that Honchkrow can make use of; it is especially useful against slower Pokemon such as Slowbro that are hit super effectively by it, but can use a status move to avoid Sucker Punch altogether. It doesn't find a place on the set most of the time though, as Honchkrow has more important moves to use. Hidden Power Grass is viable to hit Rhyperior and Swampert, but Rhyperior commonly invests heavily in Special Defense, and Swampert takes a lot of damage from Brave Bird in the first place.
Paralysis support is the most important thing that Honchkrow asks of its teammates. Several Pokemon can take a Sucker Punch, but are also naturally faster than Honchkrow, such as Raikou, Cobalion, and Crobat. Therefore, good teammates are those that can inflict paralysis upon them, such as Slowbro, Togekiss, Registeel, and Snorlax. Entry hazards are also appreciated to aid Honchkrow in its sweep; not only does it make several Pokemon much more vulnerable to Sucker Punch, it lessens the recoil taken from Brave Bird against slower opponents. Roserade, Scolipede, Rhyperior, and Qwilfish are all good hazard users, and Honchkrow can help them by trapping Xatu with Pursuit. Of course, a Xatu of your own would be a wise choice, as Honchkrow is weak to Stealth Rock and can't afford to take any more residual damage than it already does. Magneton is a good partner that pretty much eliminates the need for Superpower, because it can trap nearly all of the Steel-types in the metagame, giving Honchkrow a free sweep most of the time. Flygon functions similarly as a partner, as it lures in Steel-types to take an Outrage, but can hit them all hard with Earthquake, or even Fire Punch for Bronzong.
