Sun Boy's history continues more-or-less unchanged from his Earth Zero counterpart, which in turn continues more-or-less unchanged from his Pre-Zero Hour counterpart, excluding the Glorithverse period.
Sun Boy went through a period of depression, but came out of and became once again an effectively functioning member of the Legion. However, he was killed unexpectedly when on a mission, bravely trying to pilot the Legion Cruiser to safety.
