Bit confused by the various variants for the magic square figures and was wondering if anyone had a clear list of them?
From what I've seen there's

MS-B04 Ultra Magnus
MS-B04C Cartoon Colours (which I can't tell any difference from regular B04?)
MS-B04D Diaclone Colours

MS-B18 Optimus Prime
MS-B18B Black Deco
MS-B18G Shattered Glass Deco
MS-B18S Sleep Deco (?)
MS-B18W White Deco

Hopefully someone can confirm or deny this, and I really wish there was an easier to use list than the current 3rd party legends, like there is for MP...

 

If these versions exist, then I can confirm.

 

we have a thread that will help you out with the optimus variants.

Magic Square legend scale Optimus Prime

also, sleep is just a half dying prime *pic courtesy of @Meekutron

 

Not sure what you mean there, sorry?

That's really helpful, thank you. Any ideas about UM?

 

MS-B04C has a darker blue. There are one or two other small details, but that's about it. You can see the differences here; C is on the right

MS-B18S is dead Prime, not sleeping Prime (yes, they did a grey one for that all-of-10-seconds scene from the movie).

I can't confirm the designations, but yes, I've seen all of these for sale or listed here in one thread or another.

 

Also, in the background of one of the new pictures of Magic Square's Megatron from yesterday you can see a golden Prime as well.

 

This list includes all those one-off clear decos that were shown at some convention relatively recently:

MS-B04 Transporter (Ultra Magnus)
MS-B04C Transporter (Ultra Magnus - Animation colors)
MS-B04D Transporter (Dia Colors) (Delta Magnus/Diaclone Ultra Magnus)
MS-B04? Transporter (Ultra Magnus - Transparent w/ colors)
MS-B04? Transporter (Ultra Magnus - Transparent w/o color)
MS-B04? Transporter (Ultra Magnus - Transparent gold color)

MS-B18 Light of Justice (Optimus Prime)
MS-B18B Dark Black (Nemesis Prime)
MS-B18BS Death Color (Optimus Prime - Dead colors)
MS-B18SG Mirror Purple Light of Justice (SG Optimus Prime)
MS-B18W White Light of Justice (Ultra Magnus)
MS-B18? ????? (Optimus Prime - Gold color)
MS-B18? ????? (Optimus Prime - Transparent w/o colors)

 

And all this is what gives me hope that they will put out another version of Cosmos in better colours...

 

Thanks for all the answers  

 

Wow - Magic Square are milking this mold like crazy. I guess it's nothing new for an OP mold to be abused like this, but the speed and fury with which they released all the repaints all at once is pretty astonishing and not really in a great way.

If they trickled out the repaints and added different accessories or tweaks, I'd guess they would have had more buyers. As it is, with a rainbow of MS Optimi being dropped all at once - I don't really care about these guys at all - beyond the regular G1 version I picked up.

Don't mean to poop on anybody's parade of colorful Optimuses - just my personal feelings on the matter...
