Subaru's nickname among fans is Gaogaigar-tan for the large amount of references to that series such as Subaru's Final Fusion sequence, punching attacks reminiscent of Broken Phantom, and the reveal that Subaru and Ginga are combat cyborgs like Guy Shishioh.
Plus, the term Symmetrical Docking comes from a 3koma parodying the combination sequence of Hyoryu and Enryu (post#150779).
