Fan Casting Batman '66 Season Five Ideas

Season 5: Season Five would be the last season before Robin goes to university and Batgirl goes on to become a congresswoman (or perhaps it's the season where all of that happens). I will work those story beats in somehow over the course of this season, but the more important thing is maintaining a sense of charm with this season. It'd still have 70-80 episodes (probably), but I think some of my focus would become dedicated to Introducing the League of Assasins, and having Batman '66 embrace the vibes of James Bond or Mission Impossible.
