Ikkaku Madarame

is the 3rd Seat of the 11th Division in the Gotei 13. His Captain is Kenpachi Zaraki.

Character Outline
Ikkaku is bald, a fact that is made fun of by many. The 11th Division lieutenant, Yachiru Kusajishi, calls him either "cue-ball" or "pachinko head", a result of her fondness for giving people nicknames or when he questions her direction skills. As a result of the constant ridicule he gets, Ikkaku is very self-conscious about his baldness, to the point where he will threaten anyone that points it out. Ikkaku's bald scalp is reflective, which causes members of the 8th and 11th Divisions to mistake it as a full moon in one of the anime's omake segments, much to Ikkaku's annoyance. He also has distinctive small red markings near his eyes. Unlike most shinigami, he doesn't wear tabi with his sandals.

Despite being ranked as 3rd seat officer in his division, his rank does not reflect his fighting abilities, which are of near captain level. According to Yumichika Ayasegawa, Ikkaku is the 2nd strongest man in the 11th Division. It is unclear whether this explicitly means that he is stronger than any other male in the division (excluding Kenpachi) or whether he is the second strongest person in the division (surpassing Yachiru, its female lieutenant). Ikkaku has even achieved the bankai of his zanpakutō, putting him at a level beyond most of Soul Society's lieutenants. Ikkaku intentionally hides this fact from everyone, with the exception of those he trusts to keep it a secret. The reason he does so is to stay in the 11th Division under Kenpachi, since he believes he might be promoted or forced into becoming a captain if anyone else knew. The advantage of this secrecy is that it allows him to travel to the world of the living without his power level being placed under a limit as is required for all captain and lieutenant level Shinigami. In fact, during the second Arrancar assault, Ikkaku was the first to defeat his arrancar opponenet in his released form after he unleashed his Zanpakuto's Bankai - a feat that required the other Shinigami to also relinquish the limiters over their powers in order to fight more effectively.

In terms of attitude, Ikkaku is a stereotypical 11th Division member — violent, fight-loving, and rude; this has been noted by Tetsuzaemon Iba, among others. He loves fighting so much that he is unwilling to travel anywhere without a sword, resorting to carrying a wooden one when posing as a student at Ichigo's school. He does have a sense of loyalty and responsibility, however, unlike many of the lower-ranked 11th Division members. Ikkaku is fiercely loyal to Kenpachi, under whose command he wants to fight and eventually die.

Ikkaku has many personality traits in common with his division's captain Kenpachi Zaraki, which is why they seem to have so much respect for one another. Ikkaku considers fighting fun and tries to get as much "fun" as he can out of his opponents, so much so that he will take deadly risks to drag out the fight for as long as possible. During a fight with a challenging opponent, he is almost constantly smiling, much like Kenpachi does. Like all 11th Division members, he considers the only honorable battles to be those fought one-on-one and even the threat of death is not a reason to ignore this fact, since as a rule the winner is only determined when the other is dead. He does consider surviving an otherwise lost battle good luck, however, he's also sensible enough to carry a blood-clotting ointment in the hilt of his zanpakutō.

Ikkaku is one of the few characters in Bleach that is referred to by their given name instead of their family name, a rarity in Bleach but seemingly more common amongst the 11th Division. Only Makizō Aramaki and Tōshirō Hitsugaya have called him Madarame so far. As an odd side note, Ikkaku appears to be one of only two Bleach characters who are left handed, the other being Uryū Ishida. It's equally possible he's ambidextrous, like Lisa Yadōmaru, as he switches to his right hand during his battle with the arrancar Edrad Leones and uses his sword sheath as a secondary weapon in battle.

History
Not much is known about Ikkaku's history, but it's likely that he has been in the 11th Division since becoming a shinigami. The anime is much clearer about this; Ikkaku becomes a shinigami after hearing that Kenpachi had become the captain of the 11th Division. During Renji Abarai's time in the 11th Division, Ikkaku was Renji's senpai and taught him how to fight.

Like Rukia Kuchiki and Renji, Ikkaku came from Rukongai. At some point, he met Yumichika Ayasegawa and the two became friends. They would later have an encounter with Kenpachi Zaraki and Yachiru Kusajishi before they entered Seireitei. Kenpachi and Ikkaku fought; Kenpachi easily defeated Ikkaku and nearly killed him. When he asked Kenpachi why he didn't kill him, Kenpachi replied that if he killed Ikkaku now, he would never get another opportunity to fight Ikkaku again. He then told him not to seek death, but to consider himself lucky for not having died. The encounter is Ikkaku's main reason for staying in the 11th Division, as he wants to continue serving under Kenpachi and might not get a chance to fight him again otherwise.

Soul Society arc
Ikkaku and Yumichika are the first to encounter Ichigo Kurosaki, while Ganju runs and Yumuchika chases after him Ikkaku is left to fight Ichigo. While mostly evenly matched Ichigo comes with the victory and heals his wounds with and ointment that Ikkaku carried on him. While recovering from his injures at the 4th Division's headquaters he is interrogated by Mayuri Kurotsuchi to whom he tells no detailes of his fight. When Zaraki arrives at the scene he tells the later about Ichigo power and remarks that he will keep getting stronger. When the 11th Division decides to help Orihime Inoue they are meet in resistance by the Captains of the 7th and 9th Division along with their respective Leuitenants. Ikkaku is left to fight agaists Tetsuzaemon Iba the two fight but a victor is not decided.

Bount arc
Duirng the Bount arc Ikkaku along with Yumichika lead the 11th Division after the Bount invade Soul Society.

Arrancar arc
During the arrancar arc Ikkaku along with Yumichika, Renji, Rangiku Matsumoto and Rukia are part of the advanced force led by Captain Hitsugaya. When Grimmjow leads the second atack on the real world Ikkaku is left to fight Edorad Leones. During their fight Edorad releases his Zanpakutō, and completely overpowers him, realizing that since the others are in similar fights they wouldn't notice he releases his Bankai and wins the fight. When Luppi leads the next invasion he is force to join in a group battle compromised of Yumichika, Rangiku and him-self against Luppi. He spends the rest of his time in the real world at Keigo Asano's residence something that makes Keigo's Sister very delighted (She likes man with shaved heads).

Fake Karakura arc
When Aizen along with his three top Espada attack fake Karakura Town, he along with Yumichika Shūhei Hisagi and Izuru Kira are left to protect the four pillars that keep the real Karakura Town in Soul Society. After slaying some hollows sent to destroy his pillar, Barragan sends one of his fraccións, Po to fight him.

Zanpakutō
Hōzukimaru (鬼灯丸, Demon Light, Winter Cherry): It appears like any regular zanpakutō when sealed, but has a hollow hilt which Ikkaku stores a blood-clotting ointment in. Hōzukimaru's sealed form enables Ikkaku to employ it in battle as a normal weapon, with its sheath being wielded in his other hand to serve as a secondary weapon. Ikkaku has shown to be very proficient at how he wields his zanpakutō's default form, which leaves both his Shikai and Bankai as his "trumpcards"


 * Shikai: Its shikai command is "grow" (延びろ, nobiro, "extend" in the English version). Hōzukimaru's shikai is unusual in that Ikkaku slams Hōzukimaru's hilt (and sometimes its pommel) into its sheath to activate it when saying the command phrase. Once activated, Hōzukimaru takes on the form of what initially appears to be a yari (spear) with a wax wood shaft. The pommel also has a red horsehair tassel. While it does technically function as such, it is also a three section staff, which surprises opponents when they first attack. Ikkaku uses the command "split" (裂けろ, sakero, "split apart" in the English dub) to separate the sections, after which the sections can independently reconnect and separate again at will. Though it may seem as a Melee-type zanpakutō, Hōzukimaru appears to possess some level of wind affinity similar to those of Elemental-type zanpakutō, made apparent whenever Ikkaku spins his Shikai, generating subsequent gusts and whirlwinds that inevitably further strengthens his attacks.


 * Bankai: Ryūmon Hōzukimaru (龍紋鬼灯丸, Dragon Crest Demon Light): keeps the three-section theme but loses its yari properties. Instead, it's merely three oversized weapons connected by an equally large chain. To activate it during his battle with Edrad, Ikkaku slams the two broken pieces of his shikai back into the spear-form and says bankai. His zanpakutō's wind-based attributes become more apparent in its final and most powerful form, for the mere release causes a large tornado to materialize from the middle of the spear before amassing into a massive twister that bolsters static energy. Once the twister fades, Hōzukimaru's Bankai is finally revealed. Ikkaku's two main weapons are a Chinese Monk's spade and a standard Guan dao. Both have a traditional horsehair tassel at the hilt and a long cylindrical weight for a pommel. The pommels are connected by a heavy chain to the center section, which resembles an axe-like blade with a parallel handle forged into the blunt end and a dragon crest on one side of the blade. Despite all three weapons being of near-ridiculous proportions, Ikkaku wields them easily. Ikkaku usually holds one blade in each hand and lets the central portion "float" behind him, though he will occasionally spin the entire configuration about using the center handle as a pivot.

Ikkaku's bankai, like his shikai, is also quite unusual. Aside from the increase in power, his bankai offers no special abilities and no special defense properties. While quite capable of injuring opponents, the weapons are easily damaged. To make up for this, Ikkaku's bankai gets increasingly more powerful as the fight drags on. After he performs his bankai, the dragon crest will slowly fill in with crimson dye as Ikkaku's spiritual pressure rises. It fills faster when he spins Hōzukimaru with the center handle. Ikkaku comments that his zanpakutō is actually very lazy in battle (in stark contrast to Ikkaku himself) and needs to be woken up through causing or receiving injury; which would explain its ability to accumulate attacking power the longer the fight extends. When the crest is completely filled, Hōzukimaru is at its full power. However, the force of unleashing so much power can leave his zanpakutō's edge brittle afterwards.
