Shockwave
Shockwave has never been reissued, any Shockwave listed as reissue is likely a counterfeit.​
Packaging Guide:

-
The Hasbro logo has a white border on both the KO boxes.
-
In the "Two Ultra-Laser sounds!" box the KO has the hose breaking the top white border. (both V1 and v2 boxes)
-
The v2 box also has shockwaves arm breaking the top grid border.
-
Back of the box - Megatrons legs should be partially covered by the top left corner of the UPC, on a KO he appears on top of the UPC
Figure Guide:
-
The screws are silver/grey rather than black.
-
The KO has a shorter hose so it appears stretched in gun mode, it should be a nice half circle.
-
KO Shockwaves have come with either a silver or gold/yellow eye. (Gold/yellow is the correct color).
-
Figure molding above the legs is straighter, on a real G1 it should be at angled. (See image above).
