Katana is a superhero affiliated with the Legion of Vigilance. Katana has no actual powers, but is an expert in technology, being born to a wealthy family in Japan, with a mad scientist personality dad, and a mom who cared everything about them. Sometime in his days, a mad villain attacked the rich family's house, and killed his parents.
Katana, his real name not known, swore himself to silence until he brought the killer to justice, and taking everything he had, escaped to the Philippines, where his other relatives took him in, and he built a suit.
Katana is an expert in Parkour, and is very agile, and quick to the draw. He has many gadgets up his sleeves, including Epsilon energy, a certain kind of energy that runs on voltage, and can be lethal, or just an impenetrable shield, and can be compressed into certain shapes, creating coatings, energy shields, and blades.
Katana also has many gadgets in his suit, including energy made Shurikens, normally just a flat, circular device, but when activated, shoot out Epsilon energy, into the shape of a Shuriken blade.
Katana also has multiple "Repulse Blast" mechanisms on his palm, sending out a quick blast of energy similar to Iron Man's technology in Marvelverse, which he can use as a weapon, or as short thrusters for a little extra jump.
Katana's primary weapon, and also his namesake, is a family weapon, a Katana. Passed down for so many years, it saw action in World War II. Katana advanced his sword, by adding an Epsilon encasing, which, according to his blueprints, cuts even Diamondsteel. On the hilt there is an activation, which requires the user to press a miniature button hidden inside the golden weaving of the Katana.
