Black Cat's appearance changes early on the series. In his time with Chronos the Number XIII would be dignified by adversaries in a long, black worn out trench coat along over a black dress shirt, and his black pants to denote his extremely suitable and fitting image. Overall, his appearance suited his dubbed nick name.


Train's underground name is "Black Cat" because of the misfortune that lies in his wake. He always says to his target "I have come to deliver some bad luck" before killing them and he always completes a mission with 100% accuracy, without remorse. This is a side that Creed, a comrade of lower ranking, admires. Train´s demeanor is very cool, bordering nonchalant and almost detached until he met a girl, Saya, who was a bounty hunter who lived life as she wanted to. He then began to reveal a much warmer and more human side of himself, which Creed despised Saya for.

After giving up his life as an eraser working for Chronos, Train becomes a Sweeper (bounty hunter) and his personality changes drastically as he takes on a more lighthearted approach to life. There have been many scenes where Train is displayed carefree and even somewhat foolish. He often gets into fights with Sven (these fights involve Train letting another bounty slip through, his bottomless appitite, being way to silly, etc.) Following Saya´s way of life, he refuses to kill, and seems to take enjoyment in annoying his enemies. He isn't one to "look before he leaps" and his antics usually lead to accumulating debt that he and his partner Sven have collected from property damage. At times he is solemn, usually from regret that he was unable to help someone and other times, carefree and exuberant. There are times when Train will revert to his earlier personality when tempted.


Memories of his past as a child, in regards to the death of his biological mother and father recur within brief flashbacks and serves as the catalyst for his seemingly indifferent exterior and seamless interior. The mysterious and skilled man who is later found to be Zagine Axelox, is the one that raised Train to be the skilled gunman he is, also becomes part of a reminiscently bitter past, the realization of the cause of his own father and mother's deaths more than enough to push the young boy to the edge. He had grown to respect this teacher; this mentor of his who taught Train how to use a gun in the first place, exposing him to the a world of vigorous training, and also responsible for the Black Cat's notorious love for milk. His mentor is the one who told him that the drink will make his bones stronger. Thus, Train would be stronger.

Powers and SkillsEdit

Marksmanship: Train wields Hades, an ornate 6 shot black revolver made out of Orichalcum with an XIII engraved into its side and a lanyard (which could be from Saya's gun) it weighs 2.5 kg. He is an extremely skilled marksman, able to accurately shoot down bullets from other guns, and make a number of bullets hit at exactly the same time as well as ricochet bullets off of multiple surfaces and effictivley hit a target. He is also ambidextrous.

Railgun: When his body became infected with nanomachines he manages to manipulate them to create staticelectricity. The orichalcum in his gun Hades can act as a catalyst for the nanomachines.This allows him to focus the electricity into the barrel of Hades, turning it into a railgun. He is able to fire three of these daily, due to the energy consumption it takes to create the electricity. Train loses this ability after using it against Creed in their final battle. Burst RailgunAdded by Hazeshot.

Burst Railgun: This is Train strongest attack. Train is also able to use Sven's specially made bullets with the Railgun, as shown when he uses the Railgun to fire a Burst Bullet. He uses this to defeat Creed.
