The vikings come to Gaul and kidnap the chief's nephew. The chief sends Asterix and Obelix up north to get him back but the nephew has fallen in love with the viking chief's daughter v.v. What to do?

Caesar has had enough when another legion is hacked to pieces by the damned single indomitable village in Gaul because of the druid's magic potion, so he decides to tackle the problem at the root before conspiratorial senators exploit his humiliation: sycophant Lucullus is ordered to capture the druid (believed immortal) and push him over the edge of the earth (according to the story still believed to be flat as a pizza; actually Greeks and Romans knew better). By pure luck, Lucullus' first net traps both druid and Obelix's pet dog, so the giant and Asterix follow them by ship on the Atlantic, and crash after a storm on the North America coast in pursuit of the druid who was catapulted off the Roman galley before Lucullus triumphantly sets sails back for Europe. They find the druid and meet a tribe of Indians (believing to be in India), literally a whole New World for the equally primitive Celts. At the home front, Caesar sees his chance to overrun the village, but has to wait till the last magic potion has run out, hoping the heroes won't return. In America, the medicine man has a bad eye in the foreigners, especially when the druid proves a dangerous rival...

Obelix falls for a new arrival in his home village in Gaul, but is heartbroken when her true love arrives to visit her. However, the lovers are kidnapped by Romans; Asterix and Obelix set out to rescue them on a dangerous journey that will involve gladiators, slavers and beauracracy - and a personal encounter with the Emperor himself, Julius Caesar...

Provoked, Cleopatra bets Caesar, that she can build a big palace in 3 months. An architect is given 3 months or else.. Fortunately, Getafix/Panoramix, Asterix and Obelix come to Alexandria to help.

A group of indomitable Gauls are challenged by Roman Emperor Julius Caesar to accomplish twelve impossible tasks.

Gaul invaded! Asterix must save the Druid Getafix from the Romans.

In order to wipe out the Gaulish village by any means necessary, Caesar plans to absorb the villagers into Roman culture by having an estate built next to the village to start a new Roman colony.

The druid is accidentally hit by a menhir thrown by Obelix and loses his mind and memory.

The diminutive Asterix and his rather larger companion Obelix, warriors of the last village in Gaul still free after the Roman invasion, set out on a mission to deliver a barrel of their druid's famous magic potion to help Asterix's cousin in Britain fight off the invading Roman army.
