Astérix & Obélix

Being an American growing up in the middle of nowhere, I had no exposure to Astérix & Obélix, and to be honest, I have no idea who these characters are. I mean, I saw this MOC by vitreolum I though "cool, Astérix & Obélix". Then I realized, I have no idea who is who. Then I realized I always assumed that was their names, but as far as I knew, it could be their favorite food, or anything else, I had no idea. What I do know is these are awesome character builds, the rest I'll have to spend some time researching.
