So if Thrasher was made from the body of the X-Men "Forearm" figure, where did the head come from?

Also, what was used to make the prototype Shockwave figure?
- Head - from the BAT II (1991)
- Torso - there's a fairly distinct set of 3 grenades on the torso
- Arms -
- Legs -

Waist and upper Legs: Mirage

Torso: Air Commando Spirit v3

Arms: Sci-Fi v2? (maybe diff. forearms)
Lower legs: Deep Six v2?

I think it was mentioned that an 'Air Commando' Spirit's torso was what was used.

What about the weapons on the two figures?

thrasher has an alley gun, a rock viper gun, the gun that came with a ton of the dollar single packs......orinally with destro maybe? not sure, don't know what's in his other arm

shockwave = looks to be holding a modded heavy duty missle launcher

Part of Shockwave's backpack appears to be Barricade's. Not sure what the other part is from. I've been staring at it for 10 years thinking it was familiar and still have no idea...
