!!! Voiced by: Masahiko Tanaka (Japanese), Bill Wise (English)

A former thief, and of all the people who actively want to kill Ban, he's the most [[StalkerWithACrush deranged and obsessed]]. Yes, that includes Akabane. Nicknamed "The Enlightened," for his ability to see several seconds into the future.
* AxCrazy
* BadAssNormal: Fudo definitely qualifies for one of the few badasses not to be affiliated with [[spoiler: Witch Queen, Vodoo King, the Brain Trust and special clans]], being a normal thief who happened to learn clairvoyance out of his pure obsession with Ban.
* BestServedCold
* BloodKnight
* CombatClairvoyance: His special ability allows him to see a set number of seconds into the future. While obviously too limited for chessmastering, it turns out that knowing exactly what your opponent is about to do is [[CaptainObvious really useful in a fight.]]
* CombatSadomasochist: He loves ''receiving'' pain in battle as much as he loves dealing it out. Especially noticeable when he gets pissed off that Ban doesn't put up enough of a fight, and [[http://www.mangafox.com/manga/get_backers/v09/c001.2/93.html starts slashing up his own chest, screaming at Ban to "make him bleed" and "push him to the edge"]].
* DisproportionateRetribution: His plans for revenge against Ban can definitely be seen as this ripping the boy apart, "killing him over and over and over", slurping up his blood, violently murdering anyone that Ban pays attention to or likes, etc. Especially since he managed to get a perfectly fine replacement for his arm that works just as well as his old one (if not even better).
* DoesThisRemindYouOfAnything: ''Anything'' he says to Ban. Screaming at Ban to "meet his throbbing desires", "give his body to him", "quench his thirst"... yeeaah.
* DueToTheDead: He [[spoiler:receives a pretty darn peaceful, compassionate death courtesy of Ban. Ban even gently closes his eyes and wishes him to have good dreams]].
* EyePatchOfPower
* EvilTastesGood: He tends to say stuff like wanting Ban to "quench his thirst", and expresses a desire to "slurp up Ban's blood".
* LightIsNotGood: Dresses like a priest, but is definitely bad.
* GreenEyedMonster: If his confession to Ginji during the "Birth: Arc is any indication, he's most definitely ''very'' jealous of anyone Ban likes.
* MurderTheHypotenuse: His obsession with Ban actually gets to the point where he decides to do this to Ginji. Because Ban's eyes were only on Ginji and not on him.
* NoodleIncident: Ban ripped his arm off. We don't know how or why. Though knowing the crap that Fudou pulls off all the time, it might not be hard to guess why.
* OralFixation: He has a habit of licking his lips when he gets excited. Which means every time he fights with Ban.
* PermaStubble
* PsychicPowers: Brief clairvoyance that allows him to see seconds into the future.
* PsychoForHire: In a series filled with PunchClockVillain antagonists, he really stands out as being only interested in [[{{Yandere}} Ban]] and killing.
* StalkerWithACrush: He stalks and follows Ban ''everywhere''. Ban even {{lampshades}} it with annoyance, calling him a "damn stalker zombie".
* {{Yandere}}: For Ban.

* BigBad: Of The "Marine Red" arc.
** BigBadEnsemble: After he betrays Dokubachi
* BodyHorror: Has no heart, or any other organs for that matter. See LovecraftianSuperPower.
* EvilPlan: Wants to create a legion of super powered vampires with Marine Red
* GoodScarsEvilScars: After being scratched by a vampire
* HealingFactor: Due to his vampirism
* TheHeartless: He has no heart
* HumanoidAbomination: More like this than an actual vampire
* LovecraftianSuperPower: His body is largely a mass of undifferentiated cells (much like the [[Franchise/MassEffect Vorcha]]) making him closer to human-shaped BlobMonster or TheWormThatWalks than your traditional vampire.
* MotiveDecay: Goes from {{Revenge}} against Hitler to creating an army of super vampires [[{{Hypocrite}} Hypocrisy]] yes.
* OurVampiresAreDifferent
* {{Revenge}}: Against Hitler
* TorturedMonster: Became what he is due to Hitler's experiments
* YouHaveOutlivedYourUsefulness: [[{{InvokedTrope}} Invokes]] this against Dokubachi once the two of them acquire the [[{{MacGuffin}} Marine Red]]. Dokubachi had seen this coming, and easily slaughters Blood's men- except Blood [[{{IKnowYouKnowIKnow}} knew that Dokubachi would do that]], used the attack and subsequent CurbStompBattle to make his escape with the wine.

A protector. Formerly a pro wrestler, he's earned the nickname "Undead" for being, well, unkillable. The only opponent Ban and Ginji will actively go out of their way to completely avoid.
* TheBrute: In a more explicit way than Akabane. In his third appearance in the Manga, he chases after Ban and Ginji at over a hundred miles an hour while tossing police cars out of the way like bowling pins, all while pedaling away on a lady's bicycle!
* TheDreaded: Has the notable distinction of being the only opponent that Ban and Ginji will go to any lengths to ''avoid'' fighting.
* ImplacableMan
* PsychoForHire
* RunningGag: Such as it is. Every time he appears, the number of scars on his face and body increase (courtesy of running into the Get Backers).
