Noah is the oldest chronologically. Tiga actually died, most likely from old age, and was reborn as Daigo, his human descendant. Noah is the oldest, in the literal sense, Tiga was born long before Noah, but he was reborn, physically he's not much older than any of the other Ultras if at all since we don't know how old he was when he left Earth. THough given some of his kind had facial hair, he was most likely under 40,000 yrs which is supposed to be when male Ultras can get beards, mustaches and such.
