Other characteristics are his simplemindedness, his love and care for his dog Dogmatix, his anger when someone refers to him as being "fat", his enthusiasm for hunting and eating wild boars and beating up Romans. His catchphrase is: "Ils sont fous ces romains", which translates into "These Romans are crazy!", although he considers many other nationalities to be just as strange.
Powers and abilities
Superhuman strength: Due to the fact that he fell into a full pot the magic potion of the druid Getafix, Obelix constantly possesses a superhuman strength allowing him to lift or hit extremely heavy objects. The exact limits of his strength are unknown (or even if he has limits); he could for example pull several boats easily, which even surprises Getafix and even more impressive to lift the foot of a statue without any effort. His strength even allows him to beat and send dozens of cohorts of legionnaires flying easily. Finally his strength allows him to deliver his menhirs easily and to uproot trees.
Superhuman speed: As seen in Asterix at the Olympics, Cesar's Papyrus and Asterix and the Transitalic, Obelix can run extremely fast (perhaps even at supersonic speed) and travel huge distances easily.
Intelligence (sometimes): Despite his raw, ignorant and naive side, Obelix can sometimes be intelligent as when he realizes in Asterix among the Normans that Cacofonix has left for Lutèce.
