I was going to make one out of Universe Cyclonus, like many others customizers. However, I noticed some good mold similarities in TF Prime Starscream (limb fins, thin build, etc...).
Going with the IDW theme, he doesn't have any autobot insignias. N.A.I.L is spelled out on the left side of his chest.
UPDATE: I changed the abs+waist to better blend the vehicle mode. I wanted the more G1 all gold torso, but it doesn't work with the transformation.
The head is from Cybertron Longrack. I chopped the heads of Starscream and Longrack so that the new head could use the old joints. Despite my head being trimmed all over, it has to be removed in transformation, as the cavity for TF Prime Starscream's head is very small.
