Star Trek: EVERY Chief Of Security Ranked From WORST To BEST

19. Michael Eddington - Deep Space Nine

Eddington was the very model of a chief security officer. Ambitious, but not overbearing. Focused, but grounded in common sense. Sharp, but good at winning people over. But his defection to the Maquis, carried out right under Sisko's nose, also makes him one of the biggest security threats to the station. So it's only fair he ends up in last place.

The irony is, Eddington was actually an excellent security chief. He managed to sweet-talk the command staff despite their not being thrilled with his arrival. And that ability to handle people is an underrated skill as far as security goes.

He proved himself in battle on the bridge of the Defiant, understood the bigger picture of starbase operations and turned detective when more subtle inquiries were required. He also showed a deft touch when sabotaging the Defiant's cloaking device for Admiral Toddman while leaving the ship operational for Sisko. Although in hindsight, that was a massive red flag for just how tricky Eddington could be.

Even the fact he managed to hide his Maquis sympathies for so long speaks to his strategic mind. And successfully stealing industrial replicators for the Maquis whilst defecting was the icing on the cake.

Of course, Eddington will always be remembered more as the self-proclaimed 'Valjean', locked in a battle of wills with Sisko as 'Javert'. We just thank the prophets that there was no singing involved.
