This Jedi Insider Custom was done by Order66Outlaw who has created custom Null Arc Trooper N-5 Prudii, Sigma 6 style figure. Here is how Gabriel describes the making of this figure:

"This is my version of Null Arc Prudii from the Republic Commando short story Odds found at the end of the Novel True Colors. His base is a GI Joe Sigma 6 Windblade Snake Eyes, his head is from the Unleashed clone trooper. It was cut off and hollowed out to fit on the sigma body. Shoulder pauldron is craft foam sheet over top of very thin aluminum cut and shaped. His rifle is a sigma weapon kit bashed and modified. Modifications to him were made with Apoxie Sculpt."
