KK if i was to make my own zanpaktou id make its name gibberish cause i have no idea about japanese names
Name:Gonzabiranu(Shadow Fire)
Description:When its a katana its a simple Handle with a long black blade with a red tip at the end of it.
Shikai: Express Gonzabiranu!
Shikai Power: When its in shikai form its changes to a long red blood coloured blade with a black tip and has 2 special powers
1:Unleashes a giant wave of fire incinerating anything in its path(it moves slow so you have time to dodge)
2:Makes the whole area within 50 Meters pitch black and the only person who can see is the zanpaktou wielder at the time
Bankai: Hakumani Gonzabiranu(Godly Shadow Fires)
Bankai Power: A Ginormous wave of black fire that can travel up to 50 metres and whipes out anything in its path including its owner(so you must stay behind it if your the owner) the only thing to stop the wave is to hit the person with the zanpaktou because they cant move when the wave is forming(takes about a minute for wave to form after that its invincible)
Element: (obviously) Is fire and shadow
Bankai description: its exact same look as shikai but about 30CM longer.

Guys i hope you like that sword idea its the best i can come up with lol

alright

sealed:it looks like a normal katana except its abit shorter and the hilt is white and the guard is circular with thre hols on either side of it

Break,Hibikiseki(Sound Barrier)

Shikai appearance:it doesnt change much but the a ligh shines throught holes of the guard

Shikai ability:the blade starst to crack and then the blade shatters like glass,and then a high pitched screeching noise echoes through the air and it makes the enemy very lightheaded and unable to do a thing,the enemy also because of the zanpaktous effect it creates an illusion of the person wielding it the enemy can try to attack but the success rate of the enemies attack landing is 20 percent

Bankai:Sanshinsei Yubiwa Hibikiseki(Triple Sacred Ring Sound Barrier)

Bankai appearance:the holes on the guard send an echoe freezing the opponent where they stand and then the blade turns into three rings that hover around the enemy and then three pillars fall from the middle of the rings and there are holes in the middle of the pillars and the pillars are now surrounding the enemy and the user and the user is now just holding onto the hilt

Bankai special ability:the effect of the shikai is everlasting in bankai the screeching noise is continuous in this form yet and doest make the enemy dizzy it is merely a distraction and not only that the user can now twist the hilt and the soundwaves from the holes in middle of the pillars will lash out at the enemy in a much stronger fashion,each time the user twists the hilt the soundwaves will quikcly lash out at the enemies because the very soundwaves have become the blade of the zanpaktou,with the screeching sound lasting through the opponent will not hears the soundwaves lash out at them from the pillars

Name: Kagami Kiba (Mirror Fang)


Sealed state: A normal sized Katana

Shikai Command: Shinryaku Suru, Kagami Kiba (Invade, Mirror Fang)

Shikai Appearence: Normal Katana, but as it's slashed in front of the user it makes seven sowrds

Shikai powers: The seven swords fly around at first as they mimic the original swords movements. The user has the ability to choose how many of the swords mimic the attacks. other abilities are unknown

Bankai Command: Rei-teki Kagami Kiba. (Spiritual Mirror fang) Uses the Shikai command if it isn't in it's Shikai state

Bankai Appearence: The user has two Tekko-Kagi on each hand as a spirit like wolf appears around the user as well

Bankai: The user grows faster and stronger. they look like an animal on the battle field. they can have they spirit wolf attack if needed and can use it as armor.

Sealed: nodaichi

Shi-kai: furo miteigiken (flow undefined blade)

Appearance: just a hilt and guard

Ability: produces its blade with spiritual energy. While I prefer to keep it as a normal blade, I can surge my spiritual energy through my blade causing a raging blade with a length and width the wielder desires. By pointing the hilt at myself and the guard at the opponent if a sufficient amount of spirit energy is administered it would cause an attack comparable to a blast

Ban-kai: furo-furi miteigireiki (flow freely undefined aura)
Ability: balances shi-kai on my hand then it dissolves. my spiritual energy is now my weapon moving it to block and attack. I can dense down a portion or my spiritual energy into a zanpaktou to sword fight while directing my energy. I can also return them back into spiritual energy to cause a type of explosion

Like byakuya my ban-kai has more than one state

Ban-kai: furo-furi miteigireiki souryokutokuisei (flow freely undefined aura total energy singularity)
Dense all of my spiritual energy into one blade then burst my spirit energy to lunge me forward, this state needs a lot of concentration and doesn’t last long, but with such density I cut through most anything

Eientokei(Eternity Clock):it takes the shape of a normal katana with a gold hilt and the guard is shaped like a quadrilateral polygon

Shikai:It's release command is Slow the hands of life and once activated the guard will spin and then stop in a counterclokwise postion facing the opposite the direction then it was before

Shikai Special Ability:Eientokeis ability allows it to slow the enemies movements,once the effect has taken place the enemies movements will be much slower,making it impossible for the enemy to dodge or block any attack,i can now attack the enemy without fail and the the enemy will be unabe to do anything and will also not be able to discern being attacked until its too late,therefore making this zanpaktou,one of the most feared in all of the soul society

Bankai:Eientokei Owarijiken(End Time Eternity Clock)-The guard rips off and sends waves of white energy that disperse and become wind in the air

Bankai Special Ability:Once the wind calms everything within the area of the waves has now come to a complete stop and i can now attack the enemies without them seeing a thing,but this is only used if an enemy is able to break the shikais ability and even though it has no time limit,it seems to take alot of spirit energy to maintain so it drains me very easily
