Definitely not dialcone sludge. There are vintage KOs contemporaneous with g1 that all have crazy changes to them. I think there were kos of the kos too. They were called 'prehistory animals' and other similar names. Here's a link with a few of them: http://www.geocities.com/kidk0rrupt/frames/bootlegs.htm They've been on ebay lately too, they're really not worth a whole ton though contrary to the pitches some people write in the description area.
I think it's a KO. Can't remember there beeing a Diaclone Dinobot with any mold differences (aside from Swoop's beak) from it's Transformers version. EDIT: beaten to the punch.
yep, thats him (the red chested one)Thanks for the info everyone. at least i didn't get screwed on him (bought in a lot of 4 dinobots)paid about 10 for him.
