Unlike the other villagers, Obelix has no need to drink the druid Getafix's magic potion that gives superhuman strength, because he fell into the cauldron as a baby and its effect on him became permanent. Obelix is tall and massive. He is about tall and he weighs more than . The story of that incident is told in "How Obelix Fell into the Magic Potion When he was a Little Boy." Since this effect was not intended or expected, Getafix refuses to allow him even one more drop except under the most dire circumstances (either out of fear for his life, or fear for the lives of others should the inattentive and uncoordinated strongman become any stronger), which annoys Obelix greatly. (In "Asterix and Obelix All at Sea", it is revealed that too much of the potion can turn the drinker to stone; exactly how much is not known, but a whole cauldron will certainly do the trick. This appears to only work on grown people as Obelix did not turn to stone as a baby, or may simply occur after drinking an excessive amount while still under the effects of a previous dose). However, in "Asterix and Cleopatra," Getafix gives him a few drops to open a door in the Great Pyramid's Labyrinth but he comments that he does not see much difference between "before and after the potion" though this is presumably because Obelix is used to accomplishing any physical task with ease.
