The Terrorcons have never been reissued, any Terrorcon advertised as a reissue will most likely be counterfeit.
Packaging Guide - Giftset
Abominus has been reproduced and sold in a English language giftset which was never produced by Hasbro. The giftset was only released in Italy(GiG) and Japan (Takara).
The styrofoam is a reproduction of the GiG Abominus (Tundertron). Again it is poor quality and there are no lined circles on the styrofoam.
As there was no english language giftset, all Abominus english instruction manuals are counterfeits.
