I have an odd tendency to GIVE the extras to kids, friends or ppl here if in interested.
In terms of Destro. My default is the 25A v1 (or original flavor). The Blue comic pack version is Alexander (yeah yeah, he died, so what?). The IG Gold Head is... Uh, he just sits in a box until I feel like going the IG route.
CC. The masked w/ sword (Tripwire/CC comic pack) is my default and I BELIEVE the 5-pack CC (original cobra 5-pack) is my default. The battle armor just sits in a box in case he feels likes suiting up. Due to the way my stories play out, that might be a while!
Duke. 25A is the default until I get the Resolute version. The Bastard Era Dukes, not even SURE if I have them anymore. I know that the "duke" with desert humvee was a desert jabroni.
Snake Eyes. I took 25A v1 body and gave him the v2 head. Tho the v3 (knives on chest) is pretty darn cool too.
Storm Shadow. Since he's a bad guy in my verse, the default is the Cobra Legions 5 pack tho I THINK I swapped the head. Or something. The other Stormys represent the White Lotus Society since Tommy is no longer head of the Arashikage.
