Geriatrix is the oldest inhabitant of Asterix's village: he is mentioned as 93 years old in
Asterix at the Olympic Games (while drunk, he says he feels ten years younger, to which Asterix replies, "Well, that makes you 83, and it's time you were in bed"). Some translations make him no more than 80.
As an elder, Geriatrix demands respect (generally more than he is given). Nonetheless he dislikes being treated as old and will attack anyone who comments to that effect. In particular he often beats up the village blacksmith Fulliautomatix for refusing to fight back due to his age, and actually cries out to be attacked (in
Asterix and the Roman Agent). Geriatrix is seen to sit on the village council at times, on the face of it an entitlement deriving from being the oldest in the community. An example is on p. 11 of
Asterix and the Cauldron where he sits with Vitalstatistix, Cacofonix and Getafix, in deciding on Asterix's punishment for having violated their honor code. In
Asterix and the Roman Agent he acquires a club which he later uses to knock down
The Mansions of the Gods.
Geriatrix is against foreigners who are not from his village. He is a veteran of the
Battle of Gergovia and the
Battle of Alesia, and refers to them when excited ("It'll be just like Gergovia all over!") or distraught ("It's just like Alesia all over again!"). He has an eye for the young ladies and has a very young and beautiful wife (who appears to be in her twenties) of whom he is very possessive — particularly when Obelix is around.
