Does "Saint Seiya Omega" series have a prequel?


When Saint Seiya Omega starts, there is an evil character named Mars, which
seems to be defeated by saints before. But I have never seen him in the
previous series. Some of the plot is built on past events about which we are
assumed to have a priori knowledge. It is strongly like this series have a
prequel.

I have watched these TV series:

  * Saint Seiya
  * Saint Seiya - Hades Chapter OVA - Sanctuary
  * Saint Seiya - Hades Chapter OVA - Inferno
  * Saint Seiya - Hades Chapter OVA - Elision
  * Saint Seiya - The Lost Canvas

But still I can't tie up any of them with the currently ongoing Saint Seiya
Omega series.

Does "Saint Seiya Omega" have a prequel?




The only thing which comes between Elision and Omega is the movie [Saint
Seiya: The Heaven Chapter -
Overture](http://myanimelist.net/anime/1259/Saint_Seiya%3a_The_Heaven_Chapter_-
_Overture). The Lost Canvas is a prequel.

However, according to
[Wikipedia](http://en.wikipedia.org/wiki/Saint_Seiya_Omega), it is an anime-
original story separate from the original continuity, and you aren't assumed
to have watched all the previous series. As far as I know, Mars only appears
in Omega, so there are definitely some unexplained points which might get
answered in flashbacks or might remain forever unexplained.
