Asterix is one of the two main characters of the Asterix & Obelix franchise.
Asterix is a diminutive but fearless and cunning warrior, ever eager for new adventures. He lives around 50 BC in a fictional village in northwest Armorica (a region of ancient Gaul mostly equivalent to modern Brittany). This village is celebrated as the only part of Gaul still not conquered by Julius Caesar and his Roman legions. The inhabitants of the village gain superhuman strength by drinking a magic potion prepared by the druid, Getafix (French: Panoramix). The village is surrounded by, on one side, the ocean, and on the other by four unlucky Roman garrisons, intended to keep a watchful eye and ensure that the Gauls do not get up to mischief.
Asterix is one of the smartest and most sensible members of the village, and so he is usually chosen for any dangerous, important or exotic mission. Unlike most of the other villagers, he does not start or join brawls for the fun of it, although he does enjoy a good fight when there's cause. He rarely resorts to weapons, preferring to rely on his wits, and when necessary, his (magic potion enhanced) fists – though he carries his shortsword with him at all times, he is shown to be an occasional swordsman at best. What he does for a living is never truly known, though he is often shown going on missions, quests, or hunting. In Asterix and the Cauldron however, it is clearly stated that neither he nor Obelix have ever done anything of the sort to 'earn' money. Asterix is most often simply described as a warrior, which makes sense in light of the fact that most of the adventures he undertakes at some point require engaging an enemy.
Although no romantic interest has been introduced for Asterix yet, it seems obvious that Asterix is more susceptible than his best friend Obelix to the charms of women. He seems 'lovestruck' after receiving a kiss from Panacea towards the end of Asterix the Legionary and remains so till the last strip. He also seems similarly affected by a kiss from Latraviata, the female protagonist in Asterix and the Actress, although then it seems that Latraviata's effect on Asterix may have gone deeper, as he reflects on her (or maybe something else) during the journey back to their village. Again, while many may agree that both Asterix and Obelix share the same feelings for the same woman, Panacea (judging from the way Asterix often looks at her, trusts her, obeys her, and even goes as far as to kiss her in a hypnotic trance) it may simply be an act of instinct rising out of loneliness, as both Asterix and Obelix do not often get close to women. In the film Asterix and Obelix: Mission Cleopatra he becomes infatuated by Cleopatra's handmaiden Giemeakis (whose kiss proves to have a dramatic effect on Asterix, making him capable of superhuman feats without using the magic potion), but this is not based on anything from the original books.
Asterix' parents are former villagers who now live in the city of Condatum (Rennes), and he has cousins in Britannia (Britain). He shares his birthday with his clumsy, oversized, but extremely strong and good-hearted best friend, Obelix.
An occasional running gag is that his age is 'indeterminate'. In the collection of adventures "Asterix and the Class act", one story about his birth is called "In 35 BC" with the note "Before Caesar", referring to the time Caesar's reign began, in October 49 BC. Also, in page 24 of "Asterix and Obelix's Birthday: The Golden Book", Asterix's passport is shown, in which his date of birth is said to be LXXXV(85) BC(Before Christ). From this, Asterix's age can be placed approximately at 35 years.
One of Asterix's most recognizable features is his winged helmet, its wings often falling into positions that match his expressions.
