Gremmy Thoumeaux

is a Quincy and a member of the Wandenreich's Sternritter with the designation "V" - "The Visionary".

Appearance
Gremmy has a child-like appearance, with messy blond hair, youthful features, and red eyes. His attire is a variation of the Sternritter's typical white uniform, consisting of a loose trench coat featuring a hood and a high collar.

However, this body is only a product of his power. His real vessel is a disembodied brain in a protective casing.

Personality
Gremmy takes delight in his power and believes imagination to be the greatest force in the world. He can be cruel to those created by his power, mercilessly killing Guenael Lee. He also is quite arrogant, believing himself to be the strongest Sternritter. He is incredibly proud and confident in his own abilities, declaring that Kenpachi Zaraki cannot comprehend his abilities until he loses, he then declared that he could defeat him without even using a finger despite knowing how powerful his opponent is.

Gremmy has never thought of wanting to destroy someone because no one has ever displayed aggression toward him. However, during his fight with Kenpachi, he discovers he wishes to obliterate Kenpachi and is filled with joy at the prospect.

The Thousand-Year Blood War arc
When Guenael rises after being struck by 11th Division Lieutenant Yachiru Kusajishi, Gremmy makes a deep cut in his shoulder. Sitting inside the barrier which is healing 3rd Division Captain Rōjūrō Ōtoribashi and 9th Division Captain Kensei Muguruma, he tells Guenael he's only a product of his imagination and he will now vanish from his mind. After disposing of Guenael, Gremmy reveals he has killed the two captains, shocking 4th Division Lieutenant Isane Kotetsu. Dodging an attack from Yachiru, he imagines the bones in her hand being made of cookies, effectively making this true. He goes on to explain his powers, but he is interrupted by the arrival of Captain Kenpachi Zaraki.

Gremmy takes note of Kenpachi's strong appearance, and raises the ground to make a "stage" for he and Kenpachi to fight on. He explains his power to Kenpachi, who only tries to attack. As Gremmy tries to explain why Kenpachi can't cut him, Kenpachi presses on and slashes through part of Gremmy's right shoulder. Gremmy remains silent as Kenpachi explains that Gremmy can't imagine something that he can't cut.

Gremmy gets up, revealing he imagined himself healed. He declares that he will kill Kenpachi through his imagination without even lifting a finger. He suddenly makes lava appear to kill the captain. When Kenpachi tells Yachiru to get away he says she can't and then explains cookies to Kenpachi. He goes on to submerge Kenpachi in water and then throw him into a fissure which he then closes, stating that Kenpachi will drown within an hour. Kenpachi then breaks free and attacks Gremmy, who successfully blocks him.

After Kenpachi has Yachiru leave the battlefield to get her arm healed, Gremmy notes Kenpachi figured out how to disable his power. Kenpachi confirms this and reminds Gremmy of his claim of being the strongest Quincy before proclaiming this will not be a fight if Gremmy does not focus on him. Surrounding Kenpachi with several rectangular blocks of earth, Gremmy notes Kenpachi's reasoning of him wanting to kill the strongest combatant and tells himself he has never thought this because no one has ever displayed aggression toward him. However, Gremmy realizes that he wishes to kill Kenpachi, and is overjoyed at the prospect as he creates several dozen firearms around himself and engulfs Kenpachi in an onslaught of bullets. Gremmy creates several missiles and throws them toward Kenpachi, who withstands the explosions and notes his sword is finally beginning to enjoy himself.

While noting he feels especially good right now, Gremmy creates a shield to defend against Kenpachi's attack, only for Kenpachi to cut through it. As Kenpachi proceeds to slash him multiple times, Gremmy notes Kenpachi is taking advantage of his lack of reaction to attack him relentlessly, and thinks to himself this is impossible. When a confused Kenpachi asks him if he is imagining his own death, Gremmy realizes he is, heals his wounds, and thanks Kenpachi for pointing this out. Gremmy decides to thank Kenpachi by revealing his greatest power, and creates a clone of himself nearby. When Kenpachi attacks the clone, Gremmy claims it will not be hurt and reveals that his power of imagination is doubled in this form while pointing to a huge meteorite hurtling toward them from above. Gremmy proclaims this meteorite will obliterate both Kenpachi and the entire Seireitei.

Explaining how the meteorite will not go away if Kenpachi kills him because it is already in existence, Gremmy and his clone proclaim they will be the only ones who survive, as this is what they imagined, before telling Kenpachi he cannot do anything. However, they are shocked when Kenpachi claims they are the ones who cannot do anything, and are stunned into silence when Kenpachi destroys the meteorite with a single attack of his true Shikai.

In the aftermath of the destruction, a shocked Gremmy denounces Kenpachi as a monster. After hearing Kenpachi saying he can cut through anything, Gremmy states he'll kill Kenpachi using something without form and then multiplies himself, moves closer to Kenpachi and surrounds him with the vacuum of space. Trapped, Kenpachi cuts through one of the Gremmys, but many other Gremmys converge on him and create a massive explosion. Exhausted, Gremmy moves away and, seeing Kenpachi still standing, thinks he desperately wants to win and starts increasing his strength. His body however breaks apart due to the pressure and he falls to the ground.

He thinks about his defeat, concluding that he lost because he imagined his power to be as great as Kenpachi's and no body other than Kenpachi's could handle such force. The heavily wounded Gremmy is approached by Kenpachi. He explains his loss and then starts dissolving. When his brain falls out, he reveals his true nature and notes that he truly never used a single finger to attack the captain. As he dies, he states that he feels lonely thinking about the place he's going to where he's not going to be able to imagine anything at all.

Powers and Abilities
Immense Spiritual Power: Gremmy's spiritual power is on a level comparable to or greater than that of a captain-level Shinigami. Gremmy even claims to be the strongest Sternritter, and is able to fight on par with 11th Division Captain Kenpachi Zaraki, who is known for his incredible Reiryoku.

Reishi Manipulation: As a Quincy, Gremmy primarily absorbs Reishi from the atmosphere, and combines it with his own Reiryoku to form weapons. He has an easier time collecting this energy in environments with higher concentrations of Reishi such as in Soul Society or Hueco Mundo.


 * Hirenkyaku Expert: Gremmy is fast enough to effortlessly dodge a surprise attack from a Shikai-wielding Yachiru Kusajishi, a lieutenant renowned for her speed, despite the fact that her Shikai is also very difficult to dodge, before easily grabbing her hand mid-swing, preventing her Shikai from using its preemptive strike to harm him.


 * Gremmy has the ability to turn fantasy into reality. For example, if he imagines that the bones in someone's arm are made of cookies, this will become true. By imagining that his body is "more sturdy than the strongest steel," he can drastically increase his defense. He can instantly heal any wounds inflicted onto him by imagining that it has already healed. If Gremmy shifts his attention away from the target, it can revert to what it was before. Using this power, Gremmy can also create elements and substances from his mind, creating lava, water and even creating a gigantic stone platform and steel pillars to attack and defend against opponents and manipulate them as he sees fit. Gremmy can also create real weapons around himself, ranging from machine guns to missiles, in order to attack his opponent. However, if he is not careful, Gremmy can cause his own death by imagining it. Additionally, though he can increase his spiritual power to match the likes of an individual such as Kenpachi Zaraki, if he cannot imagine a body capable of containing that power, it can severely damage his body and kill him.


 * Life Creation: Gremmy's greatest power is his ability to create "life" with his imagination. Using this power he can clone himself, increasing his power of imagination with each clone made. This allows for him to create much more potent objects, such as a huge meteorite. By creating more clones, he can transform an area into the vacuum of space, suffocating the targets within and rupturing their lungs due to the rapid decompression caused by the difference in air pressure. The clones are invulnerable to harm. Gremmy can even create other sentient living beings using this power, having created Guenael Lee and then erasing him from existence with the same power. This power is not limited to creating other beings, he can even create a living vessel for himself.


 * Infiltration: Gremmy used his powers to appear inside Isane Kotetsu's barrier and completely mask his presence, only being noticed when he took action against a fellow Sternritter. Even Yachiru, an expert in infiltration in her own right, failed to detect him.

Quotes

 * (To Yachiru Kusajishi) "The most powerful force in this world is 'imagination.' Anything I imagine, anything at all, becomes reality."


 * (To Kenpachi Zaraki) "I am Gremmy "The Visionary". I turn fantasy into reality. You should think yourself lucky to be able to fight me. After all, I think I must be the strongest of all the Sternritter."


 * (To Kenpachi Zaraki) "'This kid’s ability is like a joke.' That’s what you’re thinking, right? I’m afraid a fighter like you... probably won’t be able to fully comprehend my strength until you’ve already lost. So shall we begin? Come and try to attack me, Kenpachi Zaraki. I won't insult you by trying to stop you with a single finger. No, I won’t even raise any fingers against you. I’ll take your life... using my mind alone."


 * "What's this? What did he say just now? If I'm the strongest, I must want to take down the strongest? I'd never even considered such a thing. From the very beginning, there was never a single person who posed a threat to me. After all, I never had any doubts. I've always known I'm the strongest of them all. There's no need to prove it by killing other people. So I never felt the need to crush somebody else with my strength. And yet... And yet why is it that right now, I want to crush this man so much?!"


 * "I want to win. I want to win, I want to win, I want to win! For the first time in my life, I feel a true desire to win against somebody!"


 * (To Kenpachi Zaraki while dying) "Ahh... I can feel my imagination reaching its limit. It makes me feel a little lonely to imagine that I'm about to enter a world...without any imagination at all..."
