Czeslaw Meyer

Czesław Meyer (チェスワフ・メイエル Chesuwafu Meieru), also known as Czes (チェス Chesu), is a young child who gained immortality aboard the Advenna Avis in 1711.

Appearance
Czesław appears to be around ten years old, although he is actually over two hundred. His dark brown hair is parted on the left side of his head and is cleanly cut and combed. He dresses nicely, typically in a casual brown suit.

Personality
Czesław does not trust anyone, but rather deceives them to his own ends. He is manipulative and sharp. Throughout the series, it is clear that he is greatly traumatized from his experiences throughout his immortal life, and he is paranoid of being devoured by his fellow immortals. He begins to trust people more after his reunion with Maiza and adoption by Ennis in 1931, and he is much more relaxed after the events of 2001.

Czesław is emotionally still a child despite his mature thought process. His display of feelings and reflex actions to unexpected situations remains as frail and impulsive as those of a young boy. Thus his immediate reactions, when wavered by unexpected downturns of events, are quite simply to scream, run, or shake in fear.

He appears to be rather lonely at some points. He is sometimes unaware about his emotional wants and needs, appearing to be quite innocent, due to how physically undeveloped he is in other areas when all his 200 years worth of time has been spent avoiding the other Immortals.

Czesław suffers greatly from trauma and PTSD from being tortured by Lebreau Fermet Viralesque for an unknown but extensive period of time. After reuniting with his alchemist friends, Czes learns to open up and place greater trust in others.

With his facade of an innocent child slowly merging with his cunning mentality, Czesław struggles in trying to find the best in people. He can be rather well-mannered, shy, smart and even quite charming. While his usual act of being well-mannered slowly turns into his adopted personality, Czesław still finds it hard to completely let go of his past. But he progresses gradually as his timid and shy personality in front of an audience slowly becomes more energetic and well-entertained. He sometimes presents himself as quite mature, shocking those who only perceive him from his physical appearances.

Biography
Czesław comes from a line of alchemists that stretch back at least as far as his grandfather, who was the teacher to Begg Garott and Lebreau Fermet Viralesque. He was born around 1701 (he is six in 1707), and was orphaned after his father died in a carriage accident.

1705: the Ironic Light Orchestra
Though Czeslaw doesn't appear personally, Begg Garott reveals in a conversation to Maiza Avaro that his teacher's grandson was the sole survivor of a horrible accident that took the lives of his parents and grandparents. As he was being adopted by Fermet, another one of his grandfather's deciples, Begg was leaving Lotto Valentino to help raise him, leaving the drug trade.

Aftermath
After he and his guardian Fermet gain immortality, Fermet tortures Czesław, claiming to be testing the limits of immortality. Eventually, Czesław manages to devour Fermet, ending his suffering. However, he comes to believe that there is no love, only deception, and that other immortals will eventually come to devour him. He becomes paranoid and trusted no one, making it his mission to devour other immortals before they can devour him. He cares little for the lives of others, even requesting that a large group of people be killed so he could find an immortal among them. In 1931, after being forgiven by Maiza, he stops hunting other immortals and lives with Ennis as her little brother.

Abilities
On the Advenna Avis Czeslaw drank the Grand Panacea and obtained true immortality, meaning he cannot age, get sick, be injured, or die via conventional means. His constant torture after that made him a rather quick healer by the standards of the Immortals but it is quite difficult to put an actual estimate because he has never been shown to heal when near others, making an exact ratio arbitrary at best. Nonetheless, his blood was remarkably fast; when Czes himself was on a speeding train his blood managed to catch up to restore him. With said torture done he also possess an inhumanely strong resistance to most kinds of pain from the tortures he's endured from Fermet.

Main resistance and immortality aside Czesław's body is fairly weak being a mere child compared to the rest of the immortals and he will retain his childhood for eternity, however his mind is very sharp. Quick-witted and surprisingly charismatic when the need arises, he nearly convinces Ladd Russo to go along with his scheme but Ladd's hatred for his lack of fear of death made this impossible. Czes's acting skills are also quite good, as he is a child he must act the part a lot and while he usually keeps to himself he is perfectly capable of making brief friendships and alliances with his charade of innocence to keep him on track.

Though not as well versed as his family or Begg Garott Czes is an alchemist by trade, specializing in explosives; he was the one responsible for the creation of Strawberry Ice Pop (the explosives that Jacuzzi's gang had raided from the Flying Pussyfoot) and would continue his alchemic pursuits for years until taking a brief pause to search for the surviving Immortals in 2001.

Relationships
Lebreau Fermet Viralesque -  Fermet was an alchemic student of Czesław's grandfather, who served as his guardian after his father died in an accident when Czes was 6 years old. He was a kind and concerned guardian at first, often commenting on the welfare of the boy when Czes was being spoiled by Maiza. When the immortals were discussing whether or not Maiza should keep the secrets of the Grand Panacea to himself Czeslaw followed Fermet's lead; when the immortals separated to avoid the threat of Szilard Quates, Czes stayed with Fermet. However at an unknown time after this Fermet began to torture Czes under the guise of testing the limits of their newly discovered regenerative abilities. After two centuries of enduring Fermet's sadism, the young Czes became convinced that there is no such thing as love. Czes extracts revenge on Fermet by devouring him, unbeknownst to Czes however Fermet had discovered some secret of avoiding death when being devoured. Fermet was also involved in the Ra's Lance Casino Incident of 1935. Czes remained traumatized by Fermet for well into the 2000s and when he discovered that Fermet was alive and well Czes was horrified.

Maiza Avaro -  Maiza first met Czes in Lotto Valentino in 1711. Though the two rarely interacted, Maiza was always concerned for Czesław's safety before and after boarding the Advenna Avis. After devouring Fermet and deciding to kill the other immortals before they can kill him, Czesław heads to New York on the Flying Pussyfoot with the goal of devouring Maiza. After meeting Isaac and Miria aboard the train and seeing their trust in him, Czes is unconditionally forgiven by Maiza and is adopted by Ennis. Maiza is one of the very few people that Czesław genuinely trusts.

Ennis - Realizing that neither have any family, Isaac and Miria present Czeslaw to Ennis as their "souvenir" from California after departing from the Flying Pussyfoot. Czes serves as her little brother, living with Ennis and Firo in their apartment. Though neither are formal members, both Ennis and Czesław frequent the Alveare together and treat each other like genuine siblings.

Mary Beriam - The two first met on the Flying Pussyfoot and were playing together in the dining car. When the White Suits (Russo Family goons) and the Black Suits (Lemures Cult) hijacked the train Czes made his escape with Mary at Natalie's request but soon abandoned her in a closet to be rid of her and try to find the identity of the immortal who he had been unknowingly sitting with in the dinning car.

In 1935 the two run into each other once again and this time Mary had grown and matured while Czes is still the same, the two kind of catch up while Carzelio Runorata and his group head into Firo's Casino to pick up Melvi Dormentaire and Felix Walken. During a moment when Mary is distracted Czeslaw escapes her sight, leaving her confused.

Trivia

 * His first name: Czesław (Pronounced in Polish as:Chess-wahf (Czesław)), contains the Slavic elements 'czes' meaning "honour" and 'slav' meaning "glory". His last name "Meyer" on the other hand comes from the middle high German word "meiger" meaning high or superior, used often for landlords.
 * Czes is 'well-versed' in Japanese in 2002. He has apparently been to Japan many times in the past (it is his fifth visit to Kyoto at the end of the 2000 arc), which we are to infer is the reason for his fluency.
