An old classic I did a year ago for the /tg/ board on 4chan: A conversion of Guts and his equipment to the D&D rules. (If you don't know who this man is, he's the protagonist of an incredible manga series called Berserk that I highly recommend. Graphic sex and violence are involved, but they have roles in the story rather than being pointless titillation.) These stats are meant to represent him immediately prior to the battle to escape Vritanis. Against a normal D&D party, I'd say his dearth of magic items makes him about CR 17.

-Prodigy (Strength): Guts gets +2 to strength and an additional +4 on all strength-based skill and ability checks. (DMG II)
-Sacrifice: Guts has been branded with the symbol of sacrifice. Evil outsiders and undead can sense his presence and general direction as long as they are within five hundred feet. Additionally, whenever an evil outsider or undead comes within a hundred feet of Guts for the first time that day, the brand gives off a sharp pain and bleeds profusely, causing him to lose one hit point for every four hit dice the creature possesses (rounding down).
• The Dragonslayer, Mastercraft Large Greatsword .
•• The Dragonslayer is treated as a Holy Ghost Touch weapon for the purposes of bypassing DR and determining whether an attack hits. This is an extraordinary ability.
•• The Dragonslayer’s size provides a wielder of medium size with a +2 bonus to AC when they fight defensively and cover in the direction of their choice when they take a total defense action.
• Berserker Armor, +1 Mithral Full Plate
•• While wearing the berserker armor, a wielder with the ability to enter a frenzy must make a will save to avoid doing so every round in which they engage in melee combat, even if they take no damage. In addition, they may not enter a rage unless already in a frenzy.
•• While the wielder is in a frenzy, the berserker armor is treated as a +2 Mithral Full Plate of Medium Fortification that cannot be removed by normal means. The wielder themself gains an additional +6 to strength and dexterity as a well as an immunity to fear, stun, nausea and death from massive damage. However, the damage they take every round is lethal instead of nonlethal, and the frenzy does not end normally as long as there are living or animate creatures within the vicinity. At the end of a frenzy, the wielder takes 1 permanent wisdom damage.
•• If the wielder has the deathless frenzy ability and would die at the end of a frenzy due to hit point loss, they instead heal to -9 hp and stabilize while permanently reducing their maximum number of hit points by the same amount.
• Prosthetic Arm
•• When equipped, the prosthetic arm can be used to hold metal items or help wield two-handed weapons. It also functions as a mastercraft gauntlet.
•• Arm Cannon, Exotic Medium Ranged Weapon (10’ range, 3d6 fire and 3d6 bludgeoning damage, 20/x2)
••• The arm cannon is a concealed weapon, requiring a DC 25 Spot or Search check to detect. If an opponent is not aware of the arm cannon, they are treated as flat-footed for the purpose of the wielder’s attack.
••• Reloading the arm cannon requires two full-round actions, each provoking an attack of opportunity
••• While in a grapple, the wielder may make a grapple check to attack with the arm cannon. If the attack hits, it automatically threatens a critical hit.
• Ammunition and Gunpowder for ten shots.
• 10 Fire Bombs, Splash Weapons (10’ range, 3d6 fire damage/1d6 splash, 20/x2)
• Rickert’s Repeating Crossbow
•• This crossbow functions as a mastercraft light repeating crossbow with two exceptions: The range is halved, and the magazines hold ten shots instead of five.
• 60 Bolts
• 5 Mastercraft Darts
• Mastercraft Dagger
• Flint and Steel
• 4 day’s trail rations
