Was searching around on yahoojp and found this weird prime, I remember seeing a black and gold one a few months back but this is the first time I have seen this
Hmm. The mould is the Takara Beast Wars Metals Convoy Jr; the regular version came carded, and was the same colours as TM Optimus Primal. However I believe there were at least 2 convention exclusive versions that came bagged. I see a bag in the BG of one of your pics, so I am assuming it came in that. I've seen a black and silver one, and (I think) a black and gold one, but never this one.
I wonder (sorry, no help here) if it was a Japanese Store Exclusive? It's definately BW:Metals Convoy Jr, but I've only seen a black and chrome color, never clear pink/red as convention exclusives.
It was a store exclusive if I remember correctly; a seller on eBay sold two of them for about $60 each (I failed to grab one). I'm not sure if it's just the picture, but I swore this was more reddish than pink.
