 The climatic final battle is between Average Joes and the Globo Gym  Purple Cobras, or in other words "Joes vs. Cobras." This is a  reference to the 80s toys and cartoon _"G.I. Joe" (1985)_ (qv),  which featured an ongoing battle between the heroic G.I. Joe team  and the evil terrorist organization Cobra. The Globo Gym Purple  Cobras logo is of a similar design to that of the evil Cobra  organization (though its purple, not red).
