The Longest RP Ever Submitted is a matter of contention among roboteers, as several posters are notorious for making excessively long RPs for many of their fights. Succotash_54 (Team Ignition) is considered by many to have the long-standing record for the longest RP, at roughly 1600 words.
Terminus vs Influenza
Terminus vs Influenza Is a potential candidate for the longest RP, clocking in at 1788 words. The length of the RP is the result of Prince Palatine and a few other posters referring to Influenza as "Clown Breath" on Skype. After Spatula threatened to add a paragraph to the RP every time the others said "Clown Breath", everyone on Skype immediately began saying "Clown Breath" repeatedly, hundreds of times.
Aware that his bluff had been called, Spatula resolved to follow through and write an excessively long and droning RP to fulfull his threat, most of which has nothing to do with the actual fight. It consists of a science fiction story (part of a series he intended to write anyway called 'Atna').
