Regular Show: The Movie - Characters & Cast

Initially, Mordecai is motivated by the desire to save the universe and not get fired by Benson. However, his primary motivation becomes understanding why his future self is evil and, after the big reveal, grappling with Rigby's betrayal. Ultimately, his motivation shifts to saving his friendship with Rigby.

Mordecai begins the film as the more responsible, yet still slacking, of the duo. His arc is one of disillusionment and forgiveness. When he discovers Rigby's betrayal, his trust is shattered, leading to a temporary end of their friendship. Through his encounter with his bitter future self and a heartfelt apology from Rigby, Mordecai learns to forgive and understands that their friendship is more important than a past opportunity. He matures by accepting Rigby's flaws and reaffirming their bond.

Rigby's main motivation is to save the universe and, more importantly, his friendship with Mordecai. He is driven by the warning from his future self and the immense guilt he carries. His actions are aimed at preventing the dark future he witnessed and earning back Mordecai's trust.

Rigby's arc is the emotional core of the film. He starts as his usual impulsive and irresponsible self, but is burdened by the secret of his past deception. His journey is one of guilt, confession, and redemption. He is forced to confront the severe consequences of his actions and must find the courage to tell Mordecai the truth, even at the risk of losing him forever. By the end, Rigby takes responsibility for his mistake and understands the true meaning of friendship.

Mr. Ross is solely motivated by revenge. He wants to punish Mordecai and Rigby for costing him the state volleyball championship and his job. This desire for vengeance consumes him, leading him to want to destroy the entire timeline as the ultimate act of retribution.

Mr. Ross is a fairly static character whose arc is one of escalating vengeance. He begins as a disgraced high school volleyball coach who blames Mordecai and Rigby for ruining his life and getting him arrested. In the future, he becomes the tyrannical Lord Ross, obsessed with using the Time-nado to erase the timeline. His arc is resolved not through his own growth, but by the heroes changing the past to prevent his turn to villainy in the first place.

Initially, Future Mordecai is motivated by a deep-seated grudge against Rigby. He believes Rigby ruined his life and is determined to ensure the timeline where their friendship ends remains intact. His motivation shifts to regret and a desire for his past self to make a different choice.

Future Mordecai's arc is a tragic one of redemption. Embittered by Rigby's past betrayal, he has become a cold, cybernetic warrior allied with Lord Ross. He initially works against his past self, but seeing the events unfold again and witnessing the potential for forgiveness, he has a change of heart. He sacrifices himself to save his younger self, admitting his regret over letting their friendship die.
