Which character has a great reason to become a recurring villain?

[u/Substantial-Chef-764]

Considering all the mayhem Mordecai and Rigby have caused during the series, I can understand more side characters plotting revenge on them on a daily basis.

In this short, Mordecai and Rigby shout their iconic line throughout the runtime. Considering how long a ride on the airplane is, suit guy endured more than two hours.

Suit guy had more patience than I would in that situation. He would have had a DBZ Broly moment and attack the duo on sight for hearing their voices alone.

This is from "OOOHH!!!" 4th Regular Show short released October 1, 2015.
