Technology & Combat Characteristics
The Gundam Heads are similar to snakes or worms, in the way that each head is supported by a long, green structure with very fast and flexible movement. Their heads partly resemble the head section of the RX-78-2 Gundam, except for the area surrounding it, as well as the mouth section, which has fangs, giving off the impression that the Gundam Heads appear more like a snake.
The Gundam Heads are rarely seen coming from the Devil Gundam directly, though they do appear to come out from the ground, (possibly due to the Devil Gundam's tentacle-like lower body somehow linking to the ground). The Gundam Heads also serve as lookouts or guards to stop any threats from approaching the main section of the Devil Gundam.
History
Gundam Heads are only ever used by the Devil Gundam, and are first seen in when Domon Kasshu and Master Asia make an unfriendly alliance, roughly half way into the series. After being attacked by several of them, Domon uses the Sekiha Tenkyoken technique to destroy them.
