Saboteurs are villains who lend their services to rivals/rival companies, with the intent of sabotage. Sabotage can be subtle or blatant with messing with the machine/system of something, depending on the motives, but it is almost always designed to ruin a rival's chance of succeeding or even destroying their business/goals completely.

The purpose is to either incriminate, put others in danger for any reason whatsoever, and to deliberately destroy, damage, or obstruct the work of others, especially for political or military advantage. Which includes subversive actions that are aimed at weakening a polity, government, effort, or organization through subversion, obstruction, demoralization, destabilization, division, disruption, and destruction.
