In English, his name is Geriatrix, derived from “geriatric,” humorously highlighting his advanced age despite his youthful energy. In the original French version, he is called Agecanonix, a clever play on âge canonique, referring to a venerable old age, often associated with long-lived figures. The Dutch version names him Nestorix, inspired by Nestor from Greek mythology, known as a wise and respected elder. In German, he is Methusalix, referencing Methuselah, the biblical figure famed for living 969 years, humorously implying that Agecanonix might be just as ancient.
