Step 1: Concept Identification: The query seeks to identify the theatrical work that includes the characters Lucky and Pozzo (erroneously transcribed as Pojo).
Step 2: Elaboration: Samuel Beckett's seminal absurdist drama, Waiting for Godot, prominently features Vladimir, Estragon, Pozzo, and Lucky. Within this play, Pozzo is depicted as a domineering master who controls his servant, Lucky, via a rope, compelling him to transport his possessions and perform mental exercises upon demand. Their presence in both acts serves as a pivotal element of dramatic progression and philosophical discourse.
Step 3: Conclusion: The characters Lucky and Pozzo are integral to the play titled Waiting for Godot.
