Although I wish I did, in their case, I'm not so sure I'd care if it was a (hopefully convincing likeness of a) knock-off. The original Sharkticon(s) was meant to represent a legion of identical cannon fodder, not unlike the 1982-85/2004/2007 "blueshirt" Cobra Troopers and Officers or Star Wars' Clone Troopers, Battle Droids, and Stormtroopers. Any (very) minor differences between them add the slightest of individuality in your legion. (For example, an older Sharkticon with chrome-chipped teeth among several better kept ones could represent the one that got 'fed'.) (In the case of the Episode I Battle Droids, so may variants were released simultaneously I don't think I'd seen any 2 -- excluding the "yellow dotted" commander -- in '99 that looked alike.)
