I don't think the one I watched is a full episode or something. It should be a trailer, and I assume it is an anime because I watched it on a VCD of a magazine about manga/anime.
I watched it during 2000-2003 if I didn't remember it wrong. But it doesn't necessarily mean that the show is a 2000-2003 production. The magazine should be older than the month I watched it.
The background of the anime seemed pretty dark. I remember a flying sun totem (not sure if it flew by itself or was the face of something else) appearing in different places and in each place there are characters fighting. And the character on the sun totem's side (I assume) always won and killed the other -- an invasion maybe.
The flying sun totem looks a bit like this pic: abstract flare around the circle, and a face (but filled up the circle part in that anime).
Sorry for giving unclear information about the anime. The only thing that still impresses me is the strange flying sun totem.
Update:
The totem was in yellow or similar colors, and was larger than the characters.
