The Other Side, also known as O.S., was a criminal organization. They were the main antagonists of the series. However, since Zane Willis had gotten captured, they fell into disarray. They were finally dissolved for good in The Final Chapter when all the remaining Other Side agents were captured by the Coopers.
The Other Side had been around since 1974, as a subversive conspiracy group that seeks to take over the world and every institution.
