Cyborg Continuity Question (Pre Infinite Crisis)

So cyborg in the late 90s was abducted and transformed by an alien race. It changed his entire body and for a few years he was basically a alien robot who could do anything. Then Star Labs was able to re create his original body so he transferred his brain into the body and looked like a human Vic Stone, this was in the late 1990s Titan series.

Then 2003 Geoff Johns Teen titans series launches and all of a sudden Vic Stone looks just like the Cyborg of old, the one we are used to seeing when he was first introduced in teen titans in the 1980s.

So how did he go from having a normal human body back to being Cyborg with all the damage done to his body? I never saw this explained in the teen titans or even titans series.
