Wow that's interesting etymology because Gundams are often piloted by terrorists(revolutionaries) and disturb the order of the world they exist in. The definition of a Gundam varies from one timeline to another. In most series it is used as an acronym to refer to something. the acronym's meaning has changed due to the various different timelines of the show. my favorite is the Cosmic era name General Unilateral Neuro-link Dispersive Autonomic Maneuver system. Thanks for adding that interesting tidbit!
