Star Trek: Deep Space Nine - Ranking Every Major Character Worst To Best

Constable Odo ran the station's security like clockwork, though perhaps not as efficiently as he would have liked, with his hands tied by Starfleet regulations. All he wanted was the freedom to be the ever-watchful eye, akin to George Orwell's Big Brother.

However, Odo was not always the stern man he let on to be. Lwaxanna Troi was the first to see the quiet struggle that he went through, allowing him to open up to her as they spent time trapped together. Their friendship would continue for years. It was however his love of Major Kira that was his main driving force.

Having met long before the Federation came to Bajor, they understood each other better than the Starfleet personnel ever could. His struggle to vocalise his feelings was, out of all people, noticed by Quark. Quark, the rogue who forever pushed Odo further and further in their game of cat and mouse, showed true friendship to the man, trying to help where he could.

Though Odo and Kira would eventually end up together, his approach to his duties rarely wavered. He took a grim delight in reminding Sisko that Starfleet had only posted Michael Eddington, security officer turned Maquis leader, to the station as they hadn't trusted Odo.

Odo would later discover that Section 31 had deliberately infected him with a devastating disease, designed to kill the Founders. Rene Auberjonois played this relevation with both betrayal and understand, displaying the maturity that he brought to the part for the duration. Auberjonois is sadly missed, and Odo will always be a symbol of the strength that he brought to the series.
