RX-274R Gundam Mk-IV "Siren" is a mobile suit from Meaningless War 0091 dojinshi. Despite being called the Mk-IV, the design is not based on ORX-012 Gundam Mk-IV but instead on the PMX-000 Messala and the obscure RX-272-2 Gundam MK-III "Halpuley" (featured in Model Graphix's Gundam WARS series) which, in turn, was loosely based on MSF-007 Gundam Mk-III.
