ROM and Captain Kirk

 ROM was based on a toy, even though the actual action figure may not have been as impressive as the character as depicted in comics.  One thing I really liked about ROM was his arch enemies - the Dire Wraiths.  They had a great design, unlike the look of most aliens.  My question is - was there ever any Dire Wraith toys sold as accessories to ROM?  Thinking back I don't remember any, and that seems like a missed opportunity to me.
