Shikai Name:Hōzukimaru
Spirit: The spirit has not been seen but jusging by the crest it is a dragon .
Command: Nobiro (Grow/Extend) , Hōzukimaru
Element:Pure Strenght
Sealed Zanpaktou: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 sealed form, which leaves both his Shikai and Bankai as his "trump cards".
Shikai: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.[2] 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
Shikai Ability: It is different than other zanpakutou because it's a spear .
Bankai Name : Ryūmon Hōzukimaru
Bankai:Keeps the three-section theme but loses its yari properties. Instead, it is merely three over-sized 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. 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.[3] 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.
Bankai Ability: Ikkaku's Bankai, like his Shikai, is 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 afterward. Ikkaku has not used his Bankai as frequently as he should be (as Iba points out), since he does not want anyone to know about it; because of this, the full extent of Ryūmon Hōzukimaru has yet to be seen.
Techniques:Ikkaku doesn't have any .
