Pepe Le Pew is the first character that comes to mind for France

Asterix

Does a webcomic count as a franchise? https://satwcomic.com/

And here are all of France's appearances: https://satwcomic.com/the-world/france

Polandball

Scandinavia and the World (comic)

It's only a matter of time before they make "The Polandball Movie"

Not specifically French, but Hetalia is straight up countries as people.

Flight of the conchords is 100% your typical New Zealander

Pepe le Pew?

Civilization?

I mean the Expedition 33 cast is basically French people.

Hetalia: Axis Powers is this during WWII.

France (フランス, Furansu) is an overly-romantic, carefree man. In the series, he is shown to have a long-held rivalry with England. He makes sexual passes at many characters. France explains away his long history of military defeats as a joke from God, but he believes he is gifted with his "charms" and his supreme cooking skills.

Dexter's Lab but only for one episode.

Girls und Panzer

Maybe I am completely misunderstanding, but wouldn't Marianne be the main character representing France?

While not about France, the prominent example that comes to mind is Star Wars personifying the United States as the Empire.

• Kantai Collection (KanColle) – A Japanese browser game (later anime) where WWII-era Japanese warships are personified as girls. Hugely popular in Japan around 2013–2016. KanColle started mostly with Imperial Japanese Navy ships, but later added foreign ones. For France, the characters are:
  • Richelieu – Personification of the French battleship Richelieu.
  • Jean Bart – Battleship, Richelieu’s sister ship.
  • Commandant Teste – Seaplane tender.
• Azur Lane – A Chinese mobile game (also with anime and manga) that includes warships from multiple countries (Japan, USA, UK, Germany, etc.) as anime girls. This one has a more international cast compared to KanColle. Azur Lane has a whole French faction called Iris Libre (Free Iris, based on Free France) and Vichya Dominion (based on Vichy France). French shipgirls include:
  • Richelieu – Battleship, leader-type character (Free Iris).
  • Jean Bart – Battleship (Vichya Dominion, later joins Free Iris).
  • Le Malin – Destroyer.
  • Le Triomphant – Destroyer.
  • Algérie – Heavy cruiser.
  • Béarn – Aircraft carrier.
  • Saint Louis – Heavy cruiser.
  • Gascogne – Battleship (super prototype type).
  • Dupleix, Émile Bertin, Vauquelin, Kersaint, Forbin, Surcouf, etc. – Various cruisers, destroyers, and subs.

PS: those two games I had in mind immediately, but I used a bit of AI to put up those lists of characters, added some links manually (for other characters just swap the character name in query)
