A Nodos is a vessel entrusted with the 'essence' of a Heroic Tribesman, and can thus transform into a member of the Heroic Tribe. The vessels have been shown to have superhuman abilities, including enhanced strength and agility, breathing in space, while being unaffected by the vacuum which would kill a normal human in over 30 seconds, and enduring the immense heat caused by atmospheric reentry. They also seem able to freely move in zero-gravitation environment. It has also been revealed that other than Age, the other Nodos are required to protect the Silver Tribe's Nodos, Yuty. Yuty has mentioned that if they do not abide by the contract the Golden Tribe has given to them, each of their tribes would be destroyed.
In extremely violent battles, such as when two or more Nodos fight, they will go completely berserk, attacking and destroying everything around them, having been consumed by their own instincts. The Silver Tribe refer to this state as being in a "Frenzy." Due to this destructive nature, the Golden Tribe decided to stop the Heroic Tribe. Aware of the Heroic Tribe having destroyed hundreds of solar systems while in Frenzy, the Silver Tribe strives to prevent multiple Nodos from fighting each other. Although in the beginning, the Nodos' powers are thought to be only that of destruction, but towards the end of the series, they are believed to be keys for the gateway to the Universe where the Golden Tribe moved to.
