This paper toy is a chibi Schrödinger, a member of the Millennium forces, and is usually directly under the command of The Major, based on the manga series Hellsing, the papercraft was created by Desubunny.
Schrödinger holds the rank of Oberstammführer (Senior Unit Leader/warrant officer) and serves in the Millennium military unit of Werewolf. He was created by Doc and while usually found sitting near the Major's throne like a pet, he also acts as an envoy for Millennium. His relationship with The Major is very different than most of the soldiers commanded by him. The Major seems to emit a sense of affection for Schrödinger, much similar to the relationship of an owner who could never be angry towards its pet cat. Due to his ability to be "everywhere and nowhere" at the same time, he has proved to be a useful spy and messenger for Millennium's forces.
Taking the form of a young boy with cat ears and a perpetual smirk, Schrödingerdresses in a Hitler Youth uniform which consists of black shorts, a yellow dress shirt, black knee high socks and a black tie. He also wears white gloves and black dress shoes. In the OVA series Schrödinger can be seen to have a tail when Doc tells him he can look at the Captain's guidebook. Though previously in the same scene he is shown to not have one and this is therefore normally associated to be a reference to his feline characteristics. Plus, while telling Zorin Blitz about when she would have been fried, he also had a tail there too, and did a fire effect on it. When that was done, his tail dissapeared again.
The exact nature of Schrödinger's abilities has yet to be defined. It is confirmed by the Major that Schrödinger only exists for as long as he is aware of himself. He was able to appear in Hellsing's conference room without difficulty, despite the high security of the building at the time. He also appeared inside Zorin Blitz's illusions while Blitz was attempting to attack Seras Victoria's mind, indicating that he can appear in mental realms as well. Schrödinger himself often states that he is "everywhere and nowhere", meaning that if he believes that he exists somewhere, then he will. In essence, his powers can be summed up as 'I think, therefore I am.' This also explains his apparent regeneration/immortality and teleportation abilities. If he thinks he's at a location at any moment, then he will be at that location. Even if Schrödinger is fatally wounded, if he believes that he is alive and unscathed, then he would be. This can be seen when Alucard drinks the blood of Rip Van Winkle. He is sitting on the ship with the hand television, while in next scene we can see him standing on the right side of the Major. A few seconds later we can see him again sitting on the ship in the same position as he said "Auf Wiedersehen" to Rip.
Hellsing is a Japanese manga series written and illustrated by Kouta Hirano. Hellsing is named after and centered around the Holy Order of Protestant Knights, originally led by Abraham Van Helsing. The mission of Hellsing is to search and destroy those that threaten the safety of the Queen and Country from the undead and other supernatural forces of evil. This organization is currently led by Sir Integra Fairbrook Wingates Hellsing, who inherited the leadership of Hellsing as a child after the death of her father. She witnessed his death which turned her from a once innocent and shy little girl to a tough and deadly force. She is protected by the faithful Hellsing family butler, a deadly foe in his own right, and former Hellsing "trashman," Walter C. Dornez, and Alucard, the original and most powerful vampire that swore loyalty to the Hellsing family after being defeated by Van Helsing one hundred years before the story takes place. These formidable guardians are joined early on in the storyline by former police officer Seras Victoria, whom Alucard turned into a vampire. She is mostly involved for satire and comedy as a new vampire trying to learn a new lifestyle.
As the scale and frequency of incidents involving the undead escalate in England and all around the world, Sir Integra discovers that the remnants of a Nazi group called Millennium still exist and are intent on reviving the Third Reich by creating a battalion of vampires. Millennium, Hellsing, and the Vatican section XIII Iscariot clash in an apocalyptic three-sided war in London, and Millennium reveals its true objective: to destroy the vampire Alucard, ending a feud begun during World War II.
