|Gate Guardian Information|
|Armor||0.5 inch Steel plating|
|Power Source||Missile fueled engines (after missiles have been fired, the Battle machine will slowly fall to the ground)|
|Weapons||Twin Blue Missiles|
The Gate Guardian has only been used by Ha-Ya-To on one occasion, while rescuing the Pilot of the Stealth Hunter.
It has been seen being used during the Battle of the Striking Venom, though it has not engaged combat: it was used to save the pilots whose battle machines had been destroyed.
It has also been seen shooting down some robots which were climbing the Sentai Fortress walls. It is possible for it to have other weapons than the twin missiles.
It's current status and location is unknown.
It is currently the smallest Battle Machine ever in Exo-Force save for 6 special edition United Kingdom Models. It is so small, that without the pilot holding its wings and legs together, it would just fall apart. It is known as A05 in battle language.
