This was something I'd mentioned earlier on the TF newbies Q thread...
Winged G1 Dinobot Sludge
A few weeks ago some guy on YouTube called JadeTransformer sent me his review on a KO Sludge which he claims is a rare prototype. I called BS and challenged him to provide conclusive evidence to his claim. He got a bit abusive and accused me of being jealous. I then also provided counter-evidence against his claim citing reliable sources from both Transformers and Diaclone. I even provided Takara's customer call number if he wanted to call Takara himself and confirm his toy as being legit.

It now seems that he's deleted all of my video comments and I just tried to post some more counter-evidence but my comment didn't show up which means that either:
1/ He's screening all comments and my comment is current awaiting approval, or...
2/ He's blocked me so that I'm unable to make any further comments

I think #2 is more likely.

So I'm now asking for anyone else with a YouTube account to post a comment on this guy's channel - don't abuse him - but to point out that his claim is indeed a load of bollocks.

So the evidence you can submit to him include:
1/ There is no mention of such a prototype in "Transformers: Generations," published by Takara (and the book does show a lot of other toy prototypes and abandoned toy concepts).
2/ There is no mention of such a variant of this toy on Diaclone.net, which lists every known Diaclone variant and has photographs of them too (here).
3/ toyarchive.com has a page covering this knock off (here). This toy is called "Prehistory Animal 3 Prontosaurus" and it has photographs of the KO in box.

There are already lots of other people who are falling for this guy's claim as you can see on his comments page. Please help me in exposing this guy and his so-called rare Dinobot for the fraud that it is.

Thank you.
