One Year War
Born Katz Howan, he is one of three orphans brought onto the White Base during the One Year War. While aboard the ship, Letz, Katz, and Kikka became a combination of mascots and troublemakers for the ship, and were involved in several incidents, including Ramba Ral's last ditch attack on the ship, as well as Char's infiltration of Jaburo, when they helped to dispose of the bombs. The latter incident lead to their being allowed to stay on the ship, even when the White Base left Earth to return to space for the final offensives at Solomon and A Baoa Qu. After the Battle of A Baoa Qu, the three kids showed their Newtype abilities, when they reached out to allow Amuro Ray to find the lifeboat on which the White Base crew had escaped the ship.
After the One Year War, Katz, Letz and Kikka are adopted by Hayato Kobayashi and Fraw Bow. During this time, Katz learned how to pilot mobile suits while helping out at his foster father's museum, piloting Zeon mobile suits from the One Year War. Like his foster father Hayato, Katz is impulsive and reckless, not to mention dangerously naive.
By the time of the Gryps Conflict, Katz now feels he's old enough to follow in the footsteps of his childhood heroes, and after helping Amuro escape Earth Federation surveillance, and joins up with the Karaba resistance fighters. After joining with the Karaba forces, Katz attempts to pilot the RX-178 Gundam Mk-II only to damage the suit and cause an enemy mobile suit to retreat. Katz make his way into space to fight alongside the Anti Earth Union Group, an ally of Karaba.
After going into space he joins with the AEUG forces and learns how to pilot a MSA-003 Nemo before taking over as the pilot of the FXA-05D G-Defenser. Teaming up with Emma Sheen, Katz supports her with the G-Defenser.
As a crew member of the Argama, he repeatedly meets Sarah Zabiarov and holds a mutual attraction with the young Titans officer. During the final battle between the AEUG, Titans and Axis fleet, Katz is killed when the G-Defenser is shot down by Yazan Gable and crashes into a wrecked battleship.
In A New Translation, Katz evaded Yazan's shots, but crashes into a meteorite. His spirit did not appear in the 3rd movie.
