Orion

The Orions are a minor Alpha Quadrant power. By as late as the 23rd century, the Orions were allegedly maintaining a policy of neutrality in interstellar affairs. Often an Orion Pirate ship would be found raiding Federation colonies, but when faced with capture the ships would activate a self-destruct device and the Orion government would disavow them as rogues (TOS comic: All of Me).

The USS Enterprise (NCC-1701) was once sucessful in capturing an Orion ship, however it is unclear as to the extent this helped shed light on Orion duplicity (TOS comic: All of Me).
