Welcome to my top 5 list before we start i point out that there will be a small bit spoiler of an final boss fight with that in mind le't start the fun.

Number 5: Bowser Mario and Luigi Bowser's inside story

Uuuuuh it's Bowser i don't have any good comment...

Now what makes this such a good battle now that we have seing how we seen him so many times before? Well to start with in this game you actually have been playing as him almost more the the bros them selves, you have gotten to know Bowser, you have powered him up gotten his minions back learned his special attacks. He has high stats, lots of hp and attack power, but if you're good enough you can use them against him making it easier to wear him down, he uses everything from goombas to shy guy's. It's good fight and since you been playing Bowser it deserves this spot.

Number 4 SA-X Metroid Fusion

Those eyes gives me the chills.

Or as I like to call it SAX like the intstrument.

First times you face it all you can do is run, mostly because it has every powerup you don't have but want. Later in the endgame when you think you're about to finish the game this appears and it is mad, so it's time for a showdown with your stalker. The first part to this fight is pretty much like a lasor fight. then it takes a much darker turn and it transforms into a hideos monster like a monster version of YOU! But it's kinda weaker then you because all it does is jump and trying to stomp you but it's still an awesome fight.

SPOILERS FOR CASTLEVANIA PORTRAIT OF RUINS!!!!

Number 3: Dracula and Death Team up - Castlevania Portrait of Ruins

What is a man? oh wait wrong entry...

Allright it's time for everyone's favourite castlevania bosses don't lie to me you know everyone is looking forward to gith these two whenever you play a new castlevania games. So which one of them deseveres the spot? How about both? Yes in portrait of ruins you have a partner, so why not give dracula a partner and why not his trusty right hand man partner in crime? Thats right in Portrait of ruins you fight them both and oh man let me tell you this is one hell of a fight. Dracula uses his classic firebolts and fireballs magic attack against you while Death uses his scythe. Sometimes they combine their power to unleash devestating attacks which is tricky to avoid and does tons of damage. This battle is a real challenge and one one of them is defeated Dracula uses Death power to transform into true Dracula where he uses magic and melee attacks to crush you. It's tough fight and incredible awesome at that.

Number 2: Biggyman - Spaltterhouse series

Show him why we call it Splatterhouse!

First of before I say why the fight is good. THIS IS BIGGYMAN NOT POLTERGEIST! POLTERGEIST WAS THE 2ND BOSS IN THE ARCADE GAME!

Ok i'm done. When we first start of this fight  we go back to old school side scrolling style payin respects to the older Splatterhouse games. Then we go back to the 3d and thats where the real fight begins, this guy has several attacks, he start by just swinging blindly into you're direction, take down his first health bar then it's jsut finish him of right? Wrong! When you try to grab him the light goes out and it becomes dark and suddenly he's trying to charge you in the dark! but then he goes back to regular attacks, this repeats when you finish him of another time but the 3rd time his down for good and we get an awesome finisher of Rick using his own chainsaw against him.

Number 1: Prometheus and Pandora Solo and team up Megaman ZX series

Another team up? Yes and this is much better, why because the fight is much more fast paced the the castlevania, though their attacks are similiar to them they are faster. Pandora uses elemental attacks while Prometheus will charge at you from all sides. in ZX advent however Prometheus will use a flame pillar attacka and Pandora uses a rotating staff shield attack they will also team attack you when you lest expect it. As i said it's like the castlevania team up I just happen to like this one better :)

And there you have it my top 5 of boss fights i think are intressting and fun.

Please tell yours in the comments.
