Siren

A fixture of IDW's early 2000s Transformers: More Than Meets the Eye universe, Siren made their debut in 2003 alongside a memorable roster that includes Sky High, Skyfall, Slugslinger, and Skids. Though their catalog footprint is compact — spanning guidebook entries and the core series through roughly 2008 — that makes each appearance all the more collectible for dedicated Transformers enthusiasts. For fans who love digging into the deeper corners of the Modern Age Transformers mythos, Siren is exactly the kind of discovery that rewards a thorough shelf.
