Age has the body of a sixteen-year-old boy, but is actually 120 years old; it is unknown how much of this time he was actually "living", as he may have been in stasis for over 100 years. Age lived on the ruined planet Oron, a world that was once verdant and peaceful, but later suffered from a cosmic cataclysm; he lived in an old, abandoned ship, and he addressed the mainframeA.I. of the ship as his mother. Age is wild by nature, but he can nevertheless be extremely good-natured. Since he was taught by the Golden Tribe, whom he considered to be his fathers, Age has limited knowledge about human society, not even knowing the meaning of 'numbers', simple words, or common phrases. Age's character may be based on the mythological hero Hercules.
Age's Nodos form is called Bellcross (ベルクロスBerukurosu?). Bellcross has a humanoid body approximately 50 feet (15 m) tall, and joints made of very large blue spheres. It is shown to have the ability to absorb its enemies' life force and release it as a destructive energy blast.Bellcross is considered to be the strongest of the remaining Heroic Tribe. Like the other remaining members of the Heroic Tribe, he apparently lives only for destruction and can apparently counter all the other 4 Nodos' powers with ease. While Frenzied, he releases powerful shock waves whenever he moves through space, powerful enough to destroy nearby ships. Iron Tribe computers calculated that if he continued to remain in Frenzy, he would ultimately release energy on the scale of asupernova explosion. Bellcross' main ability is originally thought to be existence, but it is later revealed that he is the key to The Golden Tribe's power.
