Jacques Duquesne joined the Avengers as a double agent for the Mandarin. He betrayed the Mandarin, but quit the team anyway, and joined other villainous teams opposed to the heroes. Somehow he came to be a member of the Avengers again, and died defending teammate Mantis.
I used Wonder Man for the body. The head, boots, and bracers are from Red Guardian. Hands, weapons, and belts are from the fodder bin.
Thanks for looking, and feel free to comment.

'til next time,
