10 Most Satisfying Character-Arcs In Star Trek

10. Rom

At first, it seemed like Quark was going to be Deep Space Nine's star Ferengi, but as it turned out, his idiot brother Rom ended up stealing the show.

In his early appearances, Rom was pretty pathetic. He was constantly sucking up to his brother while working in his bar, only to be scammed out of pay and forced to do the worst jobs. He slowly started to stand up for himself, eventually forming a union in Quark's bar in the episode Bar Association. The union was dissolved in the end, but only when Quark agreed to give the workers everything they demanded.

Due to a series of contrivances mostly related to his mother Ishka's relationship with Grand Nagus Zek, Rom (a radical leftist by Ferengi standards) was chosen to become the new Grand Nagus of the Ferengi Alliance.

On top of his success, Rom went from disapproving of his son Nog's friendship with a Human, to fully supporting Nog's entrance into Starfleet Academy.
