I'm not sure what a "V-Troop" is actually.
Valor vs. Venom is one part of the Joeverse I haven't delved into yet. The only reason I even know about Swamp Rats is because one comes bundled with Snake Eyes (v23).
I still had an extra Heroclix Man of Steel Soldier, so I used green stuff to mod his helmet and give him the cape thing.
I wasn't expecting it, but I think the outcome is one of the cooler looking Cobra troops I've done.
Way to go, Swamp Rat!
