Train Heartnet 🐈‍⬛

Railgun (temporary ability using nanomachines): In the final part of the manga, Train activates nanomachines in his body to generate static electricity and transform Hades into a railgun. This accelerates bullets to hypersonic speeds with massive destructive power (capable of piercing impenetrable defenses). Limited to a few shots per day due to energy consumption, he loses this ability at the end after using it to its maximum capacity against Creed. Hand-to-hand combat and endurance: Although he prefers weapons, he is agile and strong in hand-to-hand combat. He can withstand serious injuries and continues fighting thanks to his training as an assassin for Chronos. In short, Train combines surgical precision, superhuman speed, and tactical creativity, making him nearly invincible in ranged combat. He's the "Black Cat" for a reason: he brings bad luck (and death) to his targets!

Train is one of the deadliest fighters in the Black Cat universe, known for his unerring accuracy and feline speed. His skills primarily revolve around his Hades revolver, but he also excels in hand-to-hand combat and advanced tactics. Marksmanship (Superhuman Mastery): He is the best marksman in the world in the series. He can calculate complex trajectories, fire from impossible angles, ricochet bullets off multiple surfaces to hit hidden targets, and fire multiple bullets that impact the exact same point simultaneously. Furthermore, he is capable of shooting enemy bullets in mid-flight to neutralize them. Superhuman speed and reflexes: His reflexes are cat-like and extremely fast. He can dodge bullets at close range, move at speeds that generate wind barriers, and perform acrobatic attacks in mid-air. Techniques like the Black Claw: He fires bullets while spinning in the air to create a "claw attack" that leaves four deep marks. Enhanced vision: It possesses 120/20 vision (or 60/10 in some sources), six times superior to normal human vision, allowing it to detect details at great distances and achieve extreme accuracy in its shots. Main weapon: Hades: A custom six-shot revolver made of orichalcum (the toughest metal in the Black Cat universe), engraved with "XIII". It weighs 2.5 kg and has a retractable cable in the grip for use in close combat as an improvised weapon. Special bullets: Use varied ammunition, such as explosive, smoke, paralyzing, or reflective bullets for advanced ricochets.

Independent and free as a cat: He hates being controlled or given orders. He values ​​his freedom above all else and acts according to his own instincts. That's why they call him a "street cat." Initially cold and distant: During his time as Chronos's assassin (Number XIII), he is ruthless, calculating, and seemingly emotionless. He kills without remorse and maintains an indifferent attitude toward life and death. Loyal and protective of those he considers important: Despite his cold exterior, he develops deep bonds. Once someone enters his inner circle (like Sven, Eve, or Saya), he is extremely loyal and willing to risk everything to protect them. Childish and capricious in his daily life: Outside of missions, he has a very relaxed and childlike side. He loves milk (he drinks it constantly), sweets, and food in general. He can be lazy, impulsive, and throw tantrums when he doesn't get what he wants. Proud and confident: He has great confidence in his abilities (rightly so, as he is one of the best marksmen in the world). This makes him arrogant at times, but also brave and determined in combat. With a strong sense of personal justice: After Saya's death, he refuses to kill and becomes a sweeper (bounty hunter). His goal is to capture criminals alive to face trial, reflecting his shift towards a more humane morality. Sarcastic and with a dry sense of humor: He often makes ironic or mocking comments, especially with Sven. He has a very particular way of expressing affection: through teasing and tsundere behavior.

Train is a 23-year-old, but he looks much younger, resembling a teenager of about 16. He is of average height, with a slim and athletic build, ideal for his feline agility and speed. His hair is short, messy, and dark brown (sometimes with a reddish tint), with spiky strands that give him a wild and rebellious appearance. His eyes are golden and sharp, with a penetrating gaze reminiscent of a cat's, conveying cunning and determination. A distinctive feature is the Roman numeral "XIII" (13) tattoo on his left collarbone, a mark of his past as Number XIII of the Chronos. He also wears a black or red choker with a small bell hanging from it, a reference to his "street cat" persona.

Train wears his classic outfit from his time as Chronos's assassin: a long black trench coat with a high, wide collar that gives him a mysterious and elegant air, almost like a dramatically flowing cape. Underneath, he wears a fitted black shirt with the collar open, revealing part of his XIII tattoo and the choker with the bell. The ensemble is entirely in black, complemented by black trousers and boots, creating a dark and imposing silhouette that highlights his nickname, "Black Cat." This look emphasizes his cold and lethal image, with the coat billowing to accentuate his swift and stealthy movements.
