I've been busy with writing this stuff today havn't I? 

At any rate, the Omega Supreme variations, there are 3.  Black, Blue and TF gray.

The black has been called OMEGA-TRON or BLACK OMEGA and is the original version.  Releasd as Meckabot 1, and believed to have been re-released in black as Cosmo Robot. 

Later the supposed Knockoff, blue and chrome silver was called Space Tank.  However when the character in the series came out, it was in this blue version.  I have one (or most of) each of the 3 versions and I didn't think to look or take pictures of any copy rights.  But its rather hard to believe that the series would put a knockoff color skeme into the show. 

Not much more to say than that, they are just as good as Omega, and I imagine the 3 of them to represent the Decepticons, Autobots and Neutral. 

Lisence fees probably prohibited Takara and Hasbro from reproducing the toy again as a repaint, like they have done to most of the other city bots. 

I just like to see all 4 versions boxes side by side.  If there are any others out there, DO post. 

I own the black version myself and really feel this is the best one. Actually, the one I have is a Grandstand Convertor called Omegatron. Unless someone beats me to it, I'll take a pic of the (different) box later today and add it.

EDIT: Here you go. the box of Omegatron, evil leader of the Grandstand Convertors

And then there was that goody knock-off that someone posted awhile ago in Toy Discussion. It had Voltron and other parts all mixed in. Here is a really tiny pic of it.

I totally forgot about the Converters version.  So there's 3 Black Omega's, 1 Tan and 1 blue.  CRAZY! 

And, not sure if I should say thanks about the weird one...cause I thought I dreamed it, but nope its real...real UGLY that is. 

Can I see a bigger version of the Blue one?

The blue one came in the Black box.  Here's a pict of my blue one with some others and the black one on the right. 

And some picts of mine from the original Ebay posting...can't seem to find any picts of if since I got it many years ago though...damn dead hard drive.

Note the Guardian has YELLOW tracks, and Chrome parts, such as his head, chest and arms.
