3 Interesting Character Facts:
* Jr. was born as a conjoined twin. He was separated from his brother, Albedo, with no complications, but the two grew up closer than most of the U.R.T.V. units did with each other.
* Jr.'s alias, "Gaignun Kukai, Jr.", as well as the name of his ship, the Durandal, are references to a heroic poem called The Song of Roland. He also used to have a cat named Gaignun.
* Jr. is a big enough fan of the Terminator films that he made "Sayonara, baby!" one of his catch phrases (It's "Hasta la vista, baby" in the U.S. version of the film, of course). He also likes Bruce Lee, or at least he likes making Bruce Lee noises when he kicks things.
Powers:
Jr. is an excellent marksman who specializes in the use of twin pistols in battle. He also happens to be a U.R.T.V., a genetically engineered “designer child” designed as a countermeasure against U-DO, a mysterious and (seemingly) malevolent force whose nature no one in the Xenosaga universe completely understands. As a U.R.T.V., Jr. is capable of producing a special “anti-wave” energy whose wavelengths are designed to counteract the wave energy produced by the presence of U-DO. Were Jr. producing these waves by himself, the effects of the resultant waveform collision would be fairly contained (limited to the scope of a building or room, rather than a space station).

If the effort involved the efforts of over 600 U.R.T.V.s, however, enormous amounts of thermal energy would be released, resulting in the destruction of the U.R.T.V.s and everything around them (as might have occurred fourteen years ago during the Miltian conflict, had the U.R.T.V.s been fully deployed). Jr.’s anti-waves are stronger than that of the other U.R.T.V.s, and his ability to use this energy to destroy things around him is referred to as “Red Dragon”.

Jr. can pause his cellular development, effectively remaining at the same age indefinitely. He also possesses some telepathic ability, as he is able to communicate mentally with the other U.R.T.V.s and his brother, though he must be conscientious in monitoring what information he sends along, since it’s less of a mind probe than it is the sharing of two sets of thoughts. He was also the recipient of a vision just before a major offensive during the Militian conflict, which predicted the destruction of the planet Miltia as a direct consequence of the U.R.T.V.s' actions.
