The Gate Defender is a small white battle machine that was mass-produced by the humans for small defensive positions.

Alone, it is a weak battle machine, as it was easily defeated when the R-1 Rammer attacked, but when it is number, the Gate Defender is a force to be reconed with, as five of them were capable of defeating the Bridge Walker 3.


First Use


The Gate Defender shooting at a pair of Fire Vultures

One Gate Defender was piloted by Ha-Ya-To. It is the first Battle Machine he used. He fought with it against the Sentry II and the Robot Vehicle R-1 Rammer.

Later Use

Ha-Ya-To wasn't the only one to pilot a Gate Defender, along with Uplinks and Stealth Hunters, it was a mass-produced battle machine designed to attack in groups, several were seen being used by other pilots being led by Ha-Ya-To during the clean-up after the Striking Venom Attack.

Several Gate Defenders were used during the move from the Sentai Fortress up to the Golden City, it's unkown if they were ever used after that.

Final Use

In the Book series, Ha-Ya-To was seen using it at the Golden City against some Iron Condors, but ran out of power and would have plumited to his death if Hikaru hadn't saved him, soon after he recieved the Aero Booster.


The Gate Defender could be called the humans' Sentry II in terms of size and strength. The Gate Defender's armor is thin, as it is meant for speed, maneuverability and mass production. It can also fly.
