Hello, Veidt!
There were actually four anime-based comics that were planned to be produced: Tenchi Muyo, El-Hazard, Moldiver, and Phantom Quest Corps. Of these four, only Tenchi Muyo ever actually saw print. The remaining three were quietly dropped.
While I've never actually read the domestic Tenchi Muyo comic, I've heard that it was quite terrible. It may be for the best that the El-Hazard comic was never actually produced!
