This is a personal list. My history is mostly Nintendo up until recently so expect a lot of that. If you disagree with my list, name your pick below. Due to my personal history, despite playing many Kingdom Heart games, I've never finished them so they will not be mentioned here. This is also based off of Pokemon typing, this entire series is. As said, this is a personal top ten list meaning everything is my choice of my favorite bosses in this category, not the best ever.

Warrior is a bit stretching here. I only did it due to the fighting style of his boxing attacks as since boxers would fit into pokemon "fighting type" so boxer fits here as well. That being said this fight is fun, but somewhat forgettable.
Expecting Bruno? I'm not sure but I like Chuck better for some reason. Keep in mind I've only played through Yellow and Silver too so other gym leaders don't work out here either. I don't know, I found Chuck more entertaining.
This thing wasn't a bad boss fight in the original game, and even better in the 3D remake. Needing to use the Deku Flowers as well as the Deku Mask as your main form of attacks to fight the giant eyeball in the back of his head was awesome for sure. Plus, his giant sword is totally awesome, and I've always liked the design of this character.
... Whoops. Kind of a toss up here for me, I like both of these fights as much as the other. The Kirby's Adventure one you have to sword fight Meta Knight which isn't easy as he has some skills. It is a duel among rivals and honestly it is a challenging and difficult fight making it fun. Then there is the Yarn Meta Knight which is also challenging and fun, as he is possessed into fighting you using a few new powers as you have to use Yarn Kirby's abilities to face him. Both these fights are challenging and fun.
This was close to being the final boss of Assassin's Creed Brotherhood, Cesare Borgia. That being said, I picked this list before beating Assassin's Creed III. After beating it, I like this fight a little better, as the fight between Haytham and Conner is incredibly tense, as not only is it father vs. son, but you are in a prison which is being attacked by cannon fire. You are basically fighting using the scenery around you to fight, while dizzy from nearly taking a cannonball head on. Also since you've played as Haytham and his dialogue at the end certainly helps his placement here. Fight on!
It takes about 5 powerful monkeys to take this guy down. While each round is kind of boxing theme... kind of, each round is like a different boss fight. Not K. Rool's best fight, but certainly hard to forget. Also Round 5 with K. Rool being in a fist fight with Chunky is crazy. This fight is both challenging and fun, even if Kremlings do cheat.
The final boss to one of the most underrated Wii games of all time, Shinjiro caused the death of all the members of your clan, took over the entire city and temple, and is after the steel used to make your special sword so he can build an army with armor and swords made from it. There is an easy way to defeat him, but if you don't know it, expect a difficult and fun battle. Swords clash. It is the way of the samurai.
Notice a lot of these fights are fun to me? That is because a lot of them are so fantastic. This is probably my favorite boss battle from the entire Arkham series. Slade here is about as good as you are in combat, and it is hard to face him, ESPECIALLY in the harder difficulties. This game probably didn't get enough credit, as while it may not be as good as Arkham City, it was still a good game, and this fight was one of the reasons as to why.
One is a little shrimp that will make you cry, the other goes super saiyan in his final fight. Both of these fights are insanely difficult and are far worse then the actual final boss. Both of these masters run a dojo and are associated with martial arts. If you are not prepared with the best of the best team, you will be crushed. Which one is better? Probably the fight with Jinx, as he is a bit tougher, and gives you something useful outside of bragging rights, but both fights are awesome so yeah. Which fight could be number 1?
There could only be one. There was never a doubt in my mind on who took the top spot. Henry Cooldown is a beast of a fighter keeping you on your feet as the optional final boss in No More Heroes. He steals a kill from Travis, and then it turns out he is married to the girl of Travis' dreams as well as being Travis' twin brother who also happens to be a handsome foil. He has a boring design, but that doesn't stop him from being an absolute beast in the battle grounds, and he is a sword fighter which allows him to be in this category (martial arts, sword fighters, and boxers see?). He is a warrior of destruction and he is gunning for you. Also he has a ton of health and is insanely fast keeping you on your toes.
