Starting at the top left to right!
Zangetsu: Zangetsu is Ichigo's sword spirit and he has helped Ichigo train back in the "The Substitute Arc" and the "Soul Society Arc" in order to teach him the Getsuga Tensho and help achieve his bankai form. We haven't seen Zangetsu since the Bount arc and he didn't appear with Hollow Ichigo in the Arrancar arc. He joined Muramasa for awhile and helped him reach into Ichigo and pull out Hollow Ichigo, the other power source of Ichigo Zangetsu would normally be bonded to if Murmasa wasn't pulling his tricks. Ichigo beat him though and is now back to normal with Ichigo knowing Muramasa brainwashed the zanpaktos with his powers and can't be taken by him again.
Senbonzakura: Byakuya's Sword Spirit; who takes the form of a masked samurai in full-body armor. He holds just as much pride as his previous master and he recently took it upon himself to make Byakuya somehow disappear with his "Thousand blades" technique.He recently tested Byakuya to see if he was a traitor by having him take down Rukia's Zanpakuo spirit. After testing Byakuya's loyalty, he aided him in defeating Zabimaru easily with the use of his bankai, and is now fighting Ichigo being surprised he had to use Bankai against him... even though he's had to when Byakuya fought against the trained Ichigo and he did like three episodes ago. And after being knocked away by Kenpachi he fought Ichigo again before the Zanpakto retreated. He then followed Byakuya and Muramasa to the real world and battled with Ishida.Obviously Ishida los-...wait he won? Seriously!? 100+ points for filler!
Suzumebachi: Soi Fong's Zanpakuto spirit who is the size of a bee and has a stinger for an arm. Unlike her master, she has no interest in Yoruichi (saying her former master should find herself a man and you know, not go gay for the kitty girl) and thinks Soi Fon's clothes are the worst fashion statement ever. She has just stung Soi Fong once and.....honestly she could probably take out all of the other soul reapers if she had the brain to think about it.Even though she had the complete advantage to take out Soi Fon, she was still easily defeated by Soi Fon's abilities that she should have already been aware of.
Kazeshini: Hisagi's Zanpakuto spirit who takes the form of a red demon like figure who loves to fight. He seems to love the phrase "Kill and Slaughter!!" His blades were revealed awhile back and now he's engaged in a battle with Hisagi. Wanting to show the true nature of his weapon is taking lifes, like his former partner, who escaped thanks to Kira's help which annoyed the inner thrill to kill everyone swords. He has recently suffered defeat from Kira and now has been tied up, and was able to escape I suppose after Kenpachi's rampage and came back to Muramasa who gave him a chance to act on his instincts once more. Which meant to fight Ichigo and get taken out for good with a bankai Getsuga Tensho. Ichigo feels bad for breaking him, though once again he's never really met Hisagi so how would he know what his Zanpakto looks like anyway?
Haienko: A cat spirit with a large booty who seems to enjoy talking about how beautiful she is. She's Rangiku Matsumoto's Zanpkato spirit and has been described by her former owner as rude, selfish, lazy and whiny. Which I'm sure is NOTHING at all like Miss Matsumoto. She not only has a massive crush on Hynoimaru but seems to constantly get into arguments with Tobiume who she seems to hate for being uppity and flat chested. And also calls her former owner old, even though she dosen't look a day over 30, despite probably being twice that actual age. She was recently tied up together with Tobiume after being outsmarted by Rangiku and Hinamori. For reasons I can't fathom both were caged instead of beaten to the point of going back into the sword and thanks to Byakuya are now on the loose again. After providing a distraction for Ashogi Jizo to... do something, now she and Tobiume are attacking Yourochi. And kind of obvious Yourochi can just curb stomp then but at least let's hope THIS is a battle they don't escape form at least. Well they did escape from before as Yourochi left them to take care of other things but now they escaped and are fighting her again. Youruchi please just take them out, for all of our sakes okay?
Tobiume: Momo Hinamori's sword spirit. A young maiden who wears traditional Japanese clothing and holds two bells with a dull voice who likes throwing fireballs around. She also fancies Hynomiaru and also argues constantly with Haienko, hating her for being crude and skanish. Also really dislikes her old master for trying to think the best of eveyrone and being naieve. You know like a lot of people did after seeing she still might of been mind screwed by Aizen. She was recently tied up together with Haienko after being outsmarted by Hinamori and Rangiku. But are now back on the loose again thanks to Byakuya even though you'd think their arc would be over but... guess someone likes keeping them around. They were involved with the Ashogi Jizo attack went to the cave to bicker some more and are now fighting Yourochi. Who I hope decides to take them out for good (her second time fighting them) since their constant appearences are really getting grating.
Sode no Shirayuki: Rukia's sword spirit who takes the form of a beautiful white maiden. She recently just attacked Rukia and seems to have the total interest of killing her. It's revealed she wants to be free to do whatever she wants and after a long fight with Rukia was actually severly damaged by her to the point and seeing how far Rukia would go so she wouldn't hurt innocents actually made her start caring some more about what happened to her master it seems.She was recently destroyed by Byakuya, who took her down for the sole purpose of proving his loyalty to Muramasa. Her sword remains were handed over to Rukia who was shocked by these turn of events.
Gonryomaru: A man dressed up as a ronin traveler. Who uses lightning abilities against his opponents. ..Wait.....lightning? Somebody actually has a original power that hasn't been shown yet? Yes that's right it's the sword spriit of the Chojiro Sasiukabe aka the lieuntant of squad one. Who is annoyed at him not being recongnized due to well how little of an impression his former master made. Since yeah his former master dosen't even seem to be in this arc and last I checked the only fight we've ever seen him in had him defeated in one blow. Yeah that's right someone in this series fails harder then Renji if you want to believe that. And so does this guy, needing Tenken to lift him away fom a pile of rocks. Why did this guy think he could take on a captain again? Well turns out he couldn't as he was cut up by Kenpachi offscreen since he wanted to take on a real challenge. Since let's face it this guy and Sasiukbe are kind of a joke. Not like they had any real secret power that we'll never actually even see since that's just be dumb.
Minazuki: A mysterious spirit masked in a green cloak seen with some other spirits attacking Yamamoto and with all the other old captain level Zanpakto, locked him away in some sort of fire dome for most of the arc. Now that it's revealed who the other pair of Zanpakto is I can tell you she's Unohana's zanpakto. Will we see what that can do besides transport people around and heal them? Maybe as she was seen letting Ichigo chase after her but for some reason I doubt we'll actually see what she's capable of.She was recently burned too death by Ryujin Jakka after learning that Muramasa has no more interest in helping the zanpakutos.
Zabimaru: A Woman with Monkey fur around her body and a kid with a snake tail who are attached to each other by a collar. They are the Zanpakto of Renji Abarai. Originally just a monkey and snake they're true forms are quite different (perhaps thanks to Renji possibly altering his Zanpakto if that one Shinigami's Cup is to be believed). And though they argue and bicker a lot with one another, they hate Renji even more for being so pathetic and plan on crushing the show's ultimate soul reaper Jobber. They were later defeated by Renji's spirit to never give up and they came to their senses and realized they were being controlled by Muramasa, though they still seem to be able to pop back into sword spirits whenever they want. They lost against Senbonzakura but are now going to help Renji fight Byakuya and... failed offscreen and are now just laying down defeated. Way to epically fail yet again something related to Renji.
Ashisogi Jizo: A golden baby with wings? Honestly, only some major freaky character would even dare have such a spirit! That's why he's Mayuri Kurotsuchi's Zanpakto (since honestly the face of this guy gives that away). He's now fluttering in front of Isane and Iba for... some reason. He has recently interuppted Kenpachi's fight with Byakuya and...got blown up by Mayuri. ......I feel kind of bad for the little guy..
Bottom left to right:
Sogyo no Kotowari :Two very curious looking twin children spirits dressed in blue also seen attacking Yamamoto, and then holding him for most of the arc and are now fighting their master. Yes these are the Zanpakto spirits of Joshiro Ukitake who seems to have to keep fighting children, though at least these kids having his sword powers should give him more of a fight then Lilyentte at least.They were recently burned too death by Ryujin Jakka after learning that Muramasa has no more interest in helping the zanpakutos
Tenken: A red man who has fire in his mouth and stands tall with tons of power.. The Zanpakto of Sajin Komamura who just struck a powerful blow against his former master. He seems to partner up with Gonryomaru as the two of them are fighting against Soi Fon as they seem ot make a kind of unusual tag team, who had to drag his partner out of the rubble. And now the two are fighting Kenpachi. Hey remember when there was an offscreen battle between Komamura and Kenpachi in the Soul Society arc that we never got to really see? Think this will make up for their not even match in Soul Society? Well we at least see Kenpachi charge more at him so... that's something I... believe.
Hozukimaru':: Ikakku's Zanpakuto Spirit. He resembles an oni with dark brown skin and long messy orange hair. Unlike Ikakku, he has no fear over using his bankai against his opponents which he used to hurt his former master before taking off. He then fought Ikkaku again recently and after using all of his power, Hozikmaru was defeated and fell along with his master so... he may be restored or may not as honestly everyone but Renji, Ichigo and Hitsguya (even uninteonally) don't even have their sword spirits back.
Ruri iro Kujaku:A blue haired man who wears bandages with feathers. If he looks familar it's because he's Yumikchika's sword spirit and seems to be about as vein and fashion concious as his former partner. What seperates him though is caring more about appearence, hates being called Fuji Kukaju and has no problem using his full power which is a lesson one can only hope is pased on to his arrogantly vein master. He is currently taking down Yumichika easily with his true ability. Or was until Yumichika managed to get out of the attack and trick his sword into releasting it again so he could grab and strike him from behind, defeating him and sealing him away before passing out. I still like Ruri ijo more though: he may be vein, annoying and talk a lot but at least he isn't trying to hide who he is. Unlike Yumichiki who needs to come out of the closest with Ikkaku... on showing what their Zanpaktos can do to everyone else.
Hynomiaru :A man with light blue hair with a giant X mark covering his face. He is Toshiuru Hitsuguya's zanpakto, though he had no idea of that first. He recently regained his memories after fighting Hitsugaya and now sees the child as his master again even though Hitsugya's hurt but hey at least he has his zanpakto on his side at least. And he came with Toshiru into the fire shield to create an opening for Ichigo to get out. Because yeah, what really helps take care of fire? Ice attacks..... yeah I don't get it either.
Wabisuke: Kira's extremely unhealthy looking Zanpakuto. Hes a skinny man with a giant weight who seems to love enjoying coming out of nowhere to ambush others with his weight ability. He beat Kira but made the mistake of attacking Zaraki and got taken out in one blow easily. Oh well he still is the smartest for not talking that much and trying to take people out from behind so points on that.
???: A...robot..? I....don't know...what this thing is! Maybe he belongs to....
Katen Kyokotsu Second Sword: A mysterious woman with purple hair(with a skull on it) and has her face masked up. She looks like she could join the Kakashi fan club and was one of the ones who was shown going against Yamamoto and keeping him detained. This silent ninja girl is the shadowy half of Shushi Kyroaku's zanpakto who if we learned anything from in the Starrk fight is the second blade Kyroaku dosen't use as much as his other one. She was recently burned too death by Ryūjin Jakka after realizing Muramasa had no more interest in helping the other Zanpakutos.
Katen Kyokotsu First Sword: A volptorous, large breasted woman with purple hair and has a whole crossbone skull decoration on it. The other part of Shushi's zanpakto though is a lot more talkative and chatty then the shadowy ninja girl. This pirate woman seems to really be the one fighting her former master. As for why these two are seperated even though they're one sword? Because unlike Zabimaru or Sogyo no Kotawari, Katen Kyokotsu obviously has it's two parts more seperate and works more indepently off each other.She was recently burned too death by Ryūjin Jakka after realizing Muramasa had no more interest in helping the other Zanpakutos.
Gegetsuburi: Omaeda's Zanpakuto spirit. Just like his wielder he is obnoxious and holds more speed than what his looks tell you. Ichigo was able to easily take him out without much trouble due to Omaeda being knocked out and has been taken ot be researched on by Mayuri. Supposedly killed but since this is a filler arc I really doubt that's for good.
The Last Row
Muramasa: A Zanpakto that he started the Zanpakuto rebellion with his mysterious power to seperate them from their former Soul Reaper masters. He is now the leader of the Zanpakto Spirits (well the few that are still loyal to him even though he betrayed all of them) and is suspected that behind his blood tears and uber long fingernails, he has a specific hate filled reasoning behind this attack on Soul Society. And yes he does since his former master was apparently locked up by the Soul Society for using his Sword to kill Soul Reapers. One wonders why his master wasn't just killed but since when does Soul Society ever make sense? He clashed with Ichigo and had Zangetsu follow his commands. After revealing he killed his master (which was a lie) he then gets the Hollow Side of Ichigo out and now and fought. He was about to finish off Hollow Ichigo until Ichigo protected his hollow half. He was then kicked out of Ichigo's body thanks to Ichigo's inner will. After that he started wandering around The Land of Menos killing hollows for... well he said something about his body being stabalized though how that make sense I don't know. Anyway he still seems in pretty bad shape but managed to escape thanks to Byakuya's arrival on his side and has sent the Zanpakto on a mission to the Soul Society for some reason. He then showed Byakuya where Yamamoto is being held before telling the other Zanaptko to fight the Soul Reapers coming at him. He has now recently revealed his motives on wanting to free Yamamoto so he could take control of his Zanpakuto. Ichigo...easily fell for this and now he has the power of Ryujin Jakka under his command. Which he uses just to trap our heroes so he can get to the real world. Again, a plan that doesn't make any sense and he's still only around thanks to Orihime taking pity on the guy and healing him. After getting away from the arrivals of Chad and Ishida, he released Koga from his seal before Ichigo and Rukia could stop him.
