Bambietta Basterbine is a female Quincy who also resides as a member of the Vandenreich's Stern Ritter her rank is "E" - "The Explode".
Nothing is currently known about Bambietta’s life before she became a member of the Wandenreichs elite Sternritter forces.
Bambietta Basterbine is petite, well endowed, beautiful young woman with long black hair. Her attire consists of the typical Stern Ritter white uniform with some variations. Her overall appearance consists of the signature white hooded cloak, accompanied by waist-height white trench coat, knee-high boots, a white miniskirt, as-well as her black stockings, a pink heart-shaped belt buckle, and a white cap adorned with the Wandenreich insignia.
Bambietta Basterbine seems to have a notable sadistic and psychotic nature, as she tends to emit vicious and psychotic screams of joy when she is killing her enemies. A notable example of her erratic personality is when she tricked one of her underlings into her bed chambers under false pretences, and killed him. Her personality is a stark contrast to her seemingly innocent appearance.
Bambietta first appears during the first invasion of the Soul Society, alongside many of her fellow Sternritter. And upon her arrival, she began massacring countless Shinigami until she was finally stopped by the arrival of Sajin Komamura, Captain of the 7th Division. After Bambietta mocks his appearances and part in the battle, Tetsuzaemon Iba, lieutenant of the 7th Division, arrives at the battlefield at which point Sajin takes the opportunity to activate his Bankai, Kokujō Tengen Myō'ō.
Bambietta promptly activates her Quincy Medallion however and steals his Bankai for herself, and begins an off panel battle with the Shinigami. Later as Komamura tries to rally his fellow Shinigami, Bambietta expresses shock stating that h was on the verge of death only moments ago.
Bambietta later retreats along with the rest of the Wandenreich back to the Silbern, and is present at the meeting in which Yhwach, Emperor and Father of the Quincy, named Uryuu Ishida his successor, shocking her and many of the Wandenreich members in the process. While still annoyed by the events, she invites one of her subordinates into her room under false pretences and brutally bisects him to vent her frustration. She is then joined by 4 fellow Sternritter, Candice, Meninas, Liltotto, and Giselle, who begin to chastise her for killing all the attractive men when she gets frustrated and annoyed.
Bambietta is later seen during the second invasion of the Soul Society by the Wandenreich, utilizing her explosive powers to kill numerous Shinigami while noting the loss of the Bankai they had stolen prior is not exactly a surprise. She also notes that Kokujō Tengen Myō'ō left her and went to an area far from her current location. Realising that she is talking to herself due to the sudden departure of her squad mates, she begins to violently destroy the area around her until she is confronted by the unexpected arrival of captains Sajin Komamura and Shinji Hirako.
Before Bambietta can kill them, Shinji activates his Sakenade and starts to disrupt and invert her senses while showing off its potent effects, but before he could attack her, Bambietta activates her Vollständig, noting that she is happy that they got their Bankai back, as she would have been unable to activate Vollständig if she still had it herself.
Bambietta then begins to attack them with her ability “The Explosion”, which wounds Shinji stating outright that she can get around his ability by just destroying everything in the general area. As she continues her attacks she is ambushed by Momo Hinamori. Bambietta tries to kill her in response to the ambush but she is saved by Sajin who tells her not to intervene. Bambietta then begins to attack Sajin, who after receiving an attack senses something is off about her explosive power, which Bambietta confirms as her ability to fire out her own Reishi and then turn whatever her Reishi hit’s into the explosives themselves, meaning it’s almost impossible to dodge or stop them.
Bambietta then begins to send out hundreds of her bombs towards the captain, and is surprised when he is still standing after the smoke clears, but is even more shocked by the fact that his appearance under the armour has changed to that of a more human like man. Sajin then activates his improved Bankai, Dangai Jōe, and begins an attack of his own destroying large portions of the surrounding area. Bambietta then starts to attack Dangai Jōe, only to realise that her efforts are completely ineffective, Sajin then explains to her that Dangai Jōe is simply pure Reiatsu and is no longer alive making her attacks worthless so long as his Bankai is active. Bambietta confused by this continues her attacks regardless until the tables are turned and she is struck violently by Dangai Jōe, causing her explosives to be forced back into her body and detonate.
Bambietta is then seen falling from the sky, badly wounded burned and charred from the explosion, crashing into some buildings far from the battleground. Lamenting that her losing to a Shinigami is completely unforgivable, she realises she is not alone and notices that she has been joined by her squad mates, Candice, Meninas, Liltotto, and Giselle. Giselle looks at her with noticeable concern and stats that they will take care of her, an action which scares Bambietta as she pleads with them not to “do it”.
|Bambietta is a powerful Quincy, and member of the elite fighting force of the Wandenreich, the Sternritter. Her power is great enough that she was able to blast her way through the Seireitei, killing countless Shinigami in the process, and was confident enough to fight and bring down two powerful captains simultaneously. The nature of her powers also makes fighting her nigh impossible as her attacks can’t be blocked nor dodged. As a Quincy it’s safe to assume that she has a high level of skill with the ranged weapons of the Quincy, Bows, despite having never shown these skills. It’s also shown that she has a high level of skill and strength when it comes to close quarters combat with her Reishi Shortsword, being able to slice through multiple Shinigami and their weapons with simple attacks.|
|Blut Vene - A skill inherently known by all pure blooded Quincy. By allowing Reishi to flow through their veins, a Quincy is able to dramatically bolster their defence to levels where they are able to fend off direct attacks from a Captains Shikai. The defence is not completely absolute however, as sufficient power is able to tear through it, such as power from a Bankai or by a sufficiently powerful individual.|
|Blut Arterie - The counter to Blut Vene, a skill inherently known by all pure blooded Quincy. By flowing Reishi through their arteries‘, a Quincy is able to boost their damage potential to incredible levels. Very little else is known about this skill, but it's said to be the only way a Quincy is able to deal sufficient and decent damage to a Bankai wielding Shinigami.|
The Explode – Signified by the letter “E”, “The Explode” is a powerful ability that was granted to Bambietta by Yhwach, the leader of the Wandenreich, and the Father and Emperor of all Quincy. Through this ability, Bambietta is able to turn anything that her Reishi and Reiatsu touches, into powerful explosions, or bombs. She has also shown the ability to radiate this ability from her body to create large sphericle explosions of energy which are strong enough and large enough to destroy large sections of the Seireitei instantly.
The nature of this ability makes it impossible to effectively block her explosive power, but it’s been shown that it’s possible to “deflect” her attacks if they are hit by sufficient force enough to deflect them, as seen when Dangai Jōe struck her and deflected the explosion back into her.
When Bambietta activates her Vollständig, she gains a large set of Reishi wings and star shaped halo above her head, in keeping with the general Vollständig motif. This transformation increases the power of her “The Explode” greatly, as she is now able to generate small Reishi orbs beneath her wings and fire them out like small projectiles towards her target, ensuring that no area is untouched by her barrage. These Reishi orbs follow the same logic that her normal “The Explode” power follows and that anything they touch, they turn into a bomb. It’s also shown that the potency of her explosion has also increase due to the activation of her Vollständig.
Another notable trait that her Vollständig grants her is the ability of flight, due in part to the materialized Reishi wings on her back.
