His video game credits include FX Fighter, Robotech: Battlecry, and the award-winning The Journeyman Project series.

Yune first began in comics with the 1992 cult anthropomorphic series Buster the Amazing Bear and joined Jim Lee at Wildstorm Productions after a number of years as a video game designer.

[3] On July 2, 2007, at the Anime Expo in Long Beach, California, the late Adam Schiller (who went by the username "Khyron Prime" on Robotech.com's forums), hit Yune in the face with a plate full of cream pie.

Schiller's intended attacker was Harmony Gold employee and Robotech.com "webmaster" Steve Yun, with Yune as his secondary target.

After being pied, Yune picked up the plate and returned the favor to Schiller before they both posed for a picture, which was ironically taken by Steve Yun.
