It is Mercury, and Dark Mercury from the live action...
This idea got a lot more complicated than it was originally thought up of.. I was thinking something much more monotone, and much more simple.. The idea I had must be beyond me right now.
Oh yeah, I heard there might be another live action (that will feature a totally new crew and will probably feature a totally unrelated story). I got through the existing live action purely by relying 100% on fandom, because it wasn't something I would typically watch (weekday morning kids show? lol no way it would have to be sailor moon or something.) but I still ended up liking it a great deal.
Once you get past the embarrassingly cheesy graphics and Luna being a toy/kid, it is all right.

My first try at the same subject in 2005: [link]
.. omg I just realized the live action is at least 6 years old.
OK OK I have stopped editing this drawing. The other versions will be in the scraps, including a wallpaper version: [link]
Touched up AGAIN for otakon.
I think I like mercury's body being bright afterall. While darkury is all subdued and eerie glowing.
