very hard question so if you dont mind, in no specific order:
5. Alphonse Elric (Fullmetal Alchemist): couldnt have ended up in a more awesome suit of armor. so badass! really strong morale to achieve his and his brothers goals. honorable even in the face of the enemy. doesnt need to eat, sleep, drink, etc; his body is entirely metal. kicks so much ass he doesnt need a weapon.
4. Nara Shikamaru (Naruto): brilliant tactician. his only "flaw" is his lazy, laid-back, romantic, stare-the-cloud-all-day lifestyle. never wanted anything more than to be left out of everyone elses "troublesome" ways and responsibilities. "what a drag..."
3. Naota (Fooly Cooly): shy, aloof kid who constantly carries his brothers baseball bat as a momentum. eventually he DUAL WIELDS two guitars as blunt weapons; one of which is a gibson flying V and the other i forget. what other character wields a guitar, let alone dual wields two as blunt weapons?
2. Chopper (One Piece): super versatile humanoid reindeer! i always liked humanoid animals

among various forms, his smallest cutest form is the smartest of all, and then theres his hulking brawler form but thats just the beginning! if he pops one too many pills he loses control and turns into this gargantuan raging beast! sent chills down my spine when i saw that. i swear... plus hes the ship doctor of an honorable pirate crew of all professions, a doctor?!
1. Prince Ashitaka (Princess Mononoke): he rides this big awesome red elk thats really loyal. cool mount screw horses! screw dragons! gimme a big rare elk! and he was already godly with a bow and arrow to begin with but then his arm is accidently infected with a curse and he gains hellish strength; for example he can amputate arms and decapitate people with an arrow :O and if he runs out of ammo, he can catch the enemies mid-flight! bwahahaha!!
ok i put em in order afterwords. lots of other characters i love though.

beat that!!
