First of Major props to Autobot X23 for hooking me up with the digital file to make the decals for this guy. Siren started as an Energon Downshift. He was repainted and decapitated. I made his head from a Cybertron Thundercracker with added ear points. This head is based off of the Marvel comics version and not the G1 toy. Due to the molds restriction I had to place the lightbar further back on the body.
