I see on ebay quite a few "reissue" combiners like Abominus and Defensor. Are these real reissues or just knock offs? Transformers G1 Reissue Abominus Terrorcon Super Warrior SEALED NEWUSA! | eBay
Knock Offs. Those haven't had reissues officially. Tfwiki will show which have real reissues in the toy lists for each character. Real reissues also don't straight up reuse the G1 packaging.
