So I wanted to start this little series with a explanation of what im attempting to do. I will do a breakdown of the powers, strengths and weaknesses of the Zanpakutō and then match them against the other Zanpakutō.
Power Level: The level of power the Zanpakutō has (Low, Medium, High, Very High)
Power Type: What the powers it has can be used for. (Offense, Defense, Support)
Range of Effect: The range of the powers. (Melee, Melee-Ranged, Ranged)
Powers: Power classification and rundown.
Weakness: Weaknesses that may exist.
(Flowing Blade-like Flame) - Fire Manipulation
Release Command: "Reduce All Creation to Ash"
Shikai: Blade retains its form as a Katana.
Powers: Yamamoto's Zanpakutō is the oldest and most powerful fire-type Zanpakutō, and has greater attack power than all other Zanpakutō in Soul Society. When released, the blade of Ryūjin Jakka is engulfed in fire. The aura of this weapon disintegrates everything and anything which Yamamoto waves the sword at, changing it into nothing more than ash, and engulfs the surrounding landscape in a blazing firestorm, the heat of which is intense enough to scorch the sky. - (High / Offense / Ranged)
- Fortress Blaze: A release of flames used to imprison. The level of this power is so high that it can literally imprison at least 3 highly powerful captain-class combatants with relative ease. - (High / Defense / Ranged)
- Torch: a melee attack used to burn a hole within whatever the point touches. - (High / Offense / Melee)
- Flames of Hell: a technique the requires some set up in the form of implanting the tip of the blade in the ground and leaving behind a sigil that upon activation erupts a giant pillar of fire. The pillars can be set up as a surrounding trap and is powerful enough to consume the entirety of a large town as well as anyone unfortunate enough to get caught within it, including Yamamoto himself. - (High / Offense / Ranged)
Zanka no Tachi
(Longsword of the Remnant Flame) - Advanced Fire Manipulation
Bankai: a scorched ancient katana.
Powers: Upon activation, any flames previously produced by Ryūjin Jakka are absorbed into the blade. Zanka no Tachi incorporates the full power of Yamamoto's flames into the blade: the flames within the blade burn anything it cuts out of existence. Zanka no Tachi has the side-effect of depleting the moisture in an entire area (at least the size of the Seireitei), causing the air and the water to dry up. Even Tōshirō Hitsugaya's Bankai, Daiguren Hyōrinmaru, cannot be used, for its ice melts due to the intense heat of Zanka no Tachi. Yamamoto claims releasing his Bankai clads both his blade and his body in the flames of the sun, and that prolonged use of his Bankai can destroy his opponent, Soul Society, and even himself. - (Very High / Offense / Ranged)
- Longsword of the Remnant Flame, East: Rising Sun Edge: an automatically activated power that concentrates all the power of its fire into the edge of the blade. Thus anything touched by the blade gets burned out of existence. - (Very High / Offense / Melee)
- Longsword of the Remnant Flame, West: Remnant Sun Prison Garb: an automatically activated power which ability is unseen by the eyes of anyone else unless Yamamoto wills it to be seen. It engulfs his body in heat which reaches a temperature upwards of 15,000,000 degrees. Therefore, it becomes impossible to even touch him while he is using his Bankai. - (Very High / Defense / Melee)
- Longsword of the Remnant Flame, South: Great Burial Ranks of the Ten Trillion Fire Dead: an great supportive power and psychological tool. Yamamoto can bring forth the ashes of those he has killed with his zanpakutō and form them into the skeletal caricatures of themselves. They act under his control and as army. - (Very High / Support / Melee)
- Longsword of the Remnant Flame, North: Heaven and Earth End in Ashes: A slash of concentrated fire and heat which incinerates whatever it touches out of existence. Seemingly a greater version of "East" but with greater intensity and range. - (Very High / Offense / Melee)
The overall weakness of this zanpakutō is that it actually has no weakness. It is the ultimate in offensive capability and can work in the a defensive capacity as well. The only real weakness is the bankai is in itself highly destructive to everything from the moment it is activated including to Yamamoto, if left active to long it can destroy everything. The only way around its power is to find a way to sidestep it, for Sōsuke Aizen it was the creation of Wonderweiss Margela for Yhwach it was the creation of Bankai stealing Medallion. Outside of having created something that was already pre-planned to take it out of the equation, also take into account that there is no guarantee that the whatever you use will work until you try.
Zanpakutō vs. Zanpakuto
|Suzumebachi > Jakuhō Raikōben: (Loss) = Suzumebachi is a shikai while made for assassination and killing it is entirely melee which means you have to get in close to using it. Now the fact is captains in general duck or move out the way when only the shikai is released and in general getting that close to Ryūjin Jakka runs alot of risks. Now some would say well Sui-feng is gonna use shunpo and what not, i dont doubt that but looks whose wielding Ryūjin Jakka too. Maybe in someone less experienced but getting in close no matter how fast you are is a dangerous prospect. Jakuhō Raikōben this is a ranged attack but the point being it has to hits its target and get through alot of fire. Now either shikai or bankai placed against Zanka no Tachi would be completely ineffective.|
|Shinsō > Kamishini no Yari: (Loss) = As long of a reach that Shinsō has it still is simply a sword in shikai just one with spear like capabilities. Kamishini no Yari has the distinction of being even longer in reach and extremely fast plus the molecular poison. The same issue as in shikai but with the added benefit of speed. Now Gin is at an advantage for shikai and bankai cause he is at a distance away so he doesnt have to wory about attacks to his person but deflection of his own attacks is highly likely and the fire of Ryūjin Jakka can be ranged as well. Zanka no Tachi is predominately melee in usage so reaching gin is not likely but Gin reaching Yamamoto isnt either with the ultimate in offense and defense whats likely is Kamishini no Yari would be either scorched to cinders trying to attack or broken when Yama parry's the blade.|
|Kinshara > Kinshara Butōdan: (Loss) = In shikai Kinshara has a range advantage its abilities are unique but dont stand up in terms of destructive power to Ryūjin Jakka. Then we have Kinshara Butōdan while effective it deals in illusion thus making any defense nonexistent so basically its a battle of lasting long enough to effect Yama before being consumed by flames in either shikai or bankai.|
|Kyōka Suigetsu: (Loss) = For all of its power to manipulate the senses what it comes down to is whether it can deal out the offense or protect aizen defensively. Either which way you cut it the answer is essentially no it has neither so all the illusions you can make wont stop the burning.|
|Sakanade: (Loss) = Why an interesting ability it suffers the same issue as Kyōka Suigetsu. So its a automatic loss.|
|Senbonzakura > Senbonzakura Kageyoshi: (Draw > eventual loss) = The reason for the draw is simple in shikai Senbonzakura is able to be used greatly in effect for offense and defense. In bankai Senbonzakura Kageyoshi takes what the shikai can do and enhances it, think of Ryūjin Jakka but with tiny blades and not as cruel in application. For all purposes in shikai and bankai because it becomes multiple tiny blades its hard if not impossible to stop or break through. Those reasons would allow me to believe that Byakuya could hold his own in a stalemate vs Yamamoto, though not for long but far longer then anyone else, so i give it a draw.|
|Tenken > Kokujō Tengen Myō'ō: (Loss) = This goes without saying. Tenken isnt gonna be able to contend with Ryūjin Jakka when a simple block would cut right through the manifested limb. Kokujō Tengen Myō'ō relies on raw power to take out an opponent, the one bad thing is that whatever happens to the giant is reflected on Komamura. So basically a giant in flames being burned to ash likes its wielder.|
|Katen Kyōkotsu: (Draw) = One of the few blades to cross Ryūjin Jakka and live to tell about it. Its abilities are easily as much defense/offense/support and against the flame blade it may draw it into a stalemate situation. Against Zanka no Taichi well that could be left to interpretation of whether its ability to make rules can overrule the nature of the devastating bankai.|
|Suzumushi > Suzumushi Tsuishiki: Enma Kōrogi: (Loss) = Suzumushi shikai capabilities arent gonna be enough to take on Ryūjin Jakka and its bankai leaves only a extremely small window to take out Yamamoto whose without senses before Ryūjin Jakka burns away him and the area of influence his bankai takes up. Against Zanka no Taichi theres no contest.|
|Tachikaze > Tekken Tachikaze: (Loss) = Throwing destructive air blades and bombs are all we and good assuming they can get there target. Ryūjin Jakka can cut through most of that with ease. Tekken Tachikaze requires getting in close which isnt likely against Ryūjin Jakka and nonexistent against the likes of Zanka no Taichi which he wouldnt be even able to cut.|
|Hyōrinmaru > Daiguren Hyōrinmaru: (Draw > eventual Loss) = The reason for the Draw is the direct opposite of Ryūjin Jakka is being used against it. Hyōrinmaru would throw out ice Ryūjin Jakka would melt it and vice versa (except for vacuum ice). Zanka no Taichi totally negates the entire concept of Daiguren Hyōrinmaru as its subject to the destructive effect of the bankai drying out everything including the water in the air. With no water there is no possibility of the usage of Hyōrinmaru or Daiguren Hyōrinmaru. Hitsugaya would have to use Tensō Jūrin and hope that could even the playing field, the question is for how long.|
|Ashisogi Jizō > Konjiki Ashisogi Jizō: (Loss) = Ashisogi Jizō is a melee weapon based on paralysis, effective against what you can hit but not much else. Konjiki Ashisogi Jizō is a big ugly targat asking to be incinerated and even if it made use of its deadly poison the question becomes is it capable of getting through the fire of either Ryūjin Jakka or Zanka no Taichi.|
|Sōgyo no Kotowari: (Draw > eventual loss) = One of the few blades to cross Ryūjin Jakka and live to tell about it. Its ability allows it to absorb and redirect that energy turning the opponents attack agaisnt them, stands to reason any fire it comes in contact with can be used against Yama. This problem comes with the activation of Zanka no Taichi when there is no fire to realistically absorb and redirect, the concentrated effect makes the prospect of getting in close with no known abilities of its own a highly dangerous prospect.|
