Francis The Greninja

The most accurate fit for Francis Bonnefoy aka France is the final evolution to Froakie is none other than Greninja which fits so now Francis is a water ninja frog from France or Kalos since that Pokemon region is based on France so here is France in all of his glory

Francis Bonnefoy belongs to Hidekaz Himaruya

Greninja belongs to Nintendo Gamefreak
