* WhatCouldHaveBeen: A [[http://henshingrid.blogspot.com/2010/11/mecha-early-designs-and-scrapped-ideas.html Super Sentai art book]] showed that they were gonna have a giant, heavily armed fortress robot, like in ''Turboranger'' and ''Fiveman'', but didn't go through with it (from the sketches, it would've been a retooled version of the Turborangers' Turbobuilder).
