Hello. This is my first pokemon moveset post, along with my first post overall, on the smogon forums. I have, however, battled on the shoddy battle server for a while and have played quite a bit. Anyways, I have created a set for Hitmonchan, a very, very underrated pokemon. This set can be used in either UU or OU. Please respond with suggestions or questions or any other type of comments and I will respond to them. Anyways, here's the set.

Hitmonchan @Leftovers
Ability: Iron Fist
Nature:Careful
EV Spread: 252 HP, 100 Atk, 56 Def, 100 Sp.Def
Moveset:
Bulk Up
Drain Punch
Mach Punch
Thunderpunch/ Ice Punch
I created this moveset because hitmonchan has very unique traits that benefit from this set. The idea behind this set is to bring it in on something that it can force out, bulk up on the switch, and respond accordingly. Though drain punch has a mediocre base power of 60, you will find it to be a great tanking move after you factor in STAB, the boost from Iron Fist, and the bulk up. Drain Punch then becomes a high powered attack that has the invaluable effect of restoring HP. Mach Punch is there for priority and finishing off weakened foes. The decision between thunderpunch and ice punch depends on what you wish to take out. In UU, Slowbro can wall this set if you don't run thunderpunch, and you will find slowbro a common switch in to hitmonchan. However, Venusaur can come in easily on the set lacking ice punch. In OU, the recommended move is ice punch, because other than providing extremely good type coverage, it can take out many common OU poekmon, such as salamence and gliscor. Thunderpunch is viable, but is only useful in taking out gyarados. My main point is that whichever move you select, be sure to give hitmonchan teamates that could counter opposing threats.
I have already mentioned some of the common threats to this hitmonchan, and I will give pokemon that can give great support in aiding hitmonchan. Many switch-ins to hitmonchan will be pokemon trying to will-o-wisp it, so having pokemon that can benefit from it, like pokemon with flash fire or guts, are great pokemon to have with hitmonchan. In both OU and UU it is important to pair Hitmonchan with a powerful pursuiter. In UU, slowbro can wall Hitmonchan really well, so a good teammate for it is Absol, who is a powerfull pursuiter that can largely dent or even kill slowbro. In OU, the rotom forms are a huge threat to hitmon chan as well. Good, powerful pursuiters do a great job at taking out these pokemon, such as tyranitar or scizor. After these pokemon are cleared, hitmonchan will be free to set up and start tanking.
The Ev spread to this hitmonchan is unique, but necessary for htimonchan to tank to it's fullest potential. 252 Ev's in Hp are a necessity for all tanking pokemon, as it gives them that necessary bulk. The 100 sp.def ev's and a careful nature allow hitmonchan to take the most powerful of all special attacks from the metagame, including a draco meteor from salamence or latias, fire blast or overheat from heatran, an adaptibility tria attack from porygon-z, and many more (I will show calculations at the bottom). The defensive ev's allow hitmonchan to handle a common pokemon that many people think can take hitmonchan, which is scizor. With the 100 defense ev's, hitmonchan is 3HKO'd by a choice banded, technincian bullet punch (Which does 38.33-45.33%) by following a simple strategy. Switch hitmonchan in on a well-predicted bullet punch, bulk up the next turn and then drain punch to restore a lot of that lost hp. With leftovers healing, hitmonchan will never he killed by the third bullet punch. The 100 atk ev's are there to give hitmonchan some extra power.
Calculations for Damage from Common Special Attacks with 100 Special Defense EV's, 252 HP Ev's and a Careful Nature:
(All at Sp.Atk Boosting Nature)
Max Sp.Atk Salamence Draco Meteor: 56.57-66.44%
Max Sp.Atk Latias Draco Meteor: 56.57-66.44%
Max Sp.Atk Heatran Fire Blast: 54.6-64.14%
Max Sp.Atk Heatran Overheat: 63.84-74.67%
Max Sp.Atk Porygon-Z Adaptibility Tri Attack: 50.32-59.21%
(If you have any other calculations you ant me to do, just let me know and I will be happy to do it)
My View
I have had a lot of experience with this hitmonchan set. This thing has saved me int battle many times, giving me comeback after comeback, sometimes sweeping entire teams. As long as you have a way with dealing with Hitmonchan's common counters, I'm sure you will find it to serve you very well in battle. I have always felt that hitmonchan was treated unfairly and seen as a weaker version of the other hitmon's. However, this set is meant to play to hitmonchan's strength's and abilities that set it apart from it's hitmon brethen, such as iron fist and drain punch. The set's suggested for hitmonchan on the official lists are much better on the other more stronger fighting pokemon.
Please respond with any type of comment what so ever. I hope one day for this set to be one the smogon university as an official moveset, so I will need a lot of support. Thank you.
