RX-121-1 Gundam TR-1 Hazel Custom
An experimental custom variant of the Gundam TR-1 Hazel Mobile Suit developed by the Titans. It was one of the first Titan MS that used the thrusters on its shield binders as powerful aerospace boosters.
Data from the research on this machine and its testing by the Titans Test Team led to the development of the cutting edge Gaplant variable geometry MS years later.
