Blood for the Baron!

PS: My mistake. In the hurry I wrote "Copncurrence", and it's "Concurrence". Also, to avoid confusions, I must say that the Concurrence had other members (Starscream being the only non-human one), but they were not Joe-related

Hey man, it's simple enough to edit your posts, there's a link in the top right corner.

Thank you Baron. I will not use it right now because that would leave the recent posts un-understandable, but I will remember it next time

I'll repeat the question, so no one has to go back to find it:
What's the name of the human villain in Transformers who steals an Oktober Guard jet and, years later, is part of "The Concurrence" along with Gen Blitz and Iron Klaw?

Red Scream?

No. He is a Transformers villain, but all his appearances have involved a sort of GI Joecrossover

Lord Chumley

That's right! He was a trophy hunter who wanted to get Optimus Prime's head (Comic's Shockwave had already done that, no?)

It's your turn, Sundance

who was the 'Young Master' in the Arishikage Clan?

Storm Shadow (Tommy Arashikage)

correct
