12 Star Trek Characters Who Changed The Most
12. Quark
Everyone's favourite Ferengi started life as something of....well something of an idiot, really. Not in the same way that Rom started as a literal idiot, but the schemes and plans that Quark attempted to enact in the early episodes of Deep Space Nine have, with the evolution of the character, served as a poor representation of a well rounded, popular character.
Quark became the archetype for all things Ferengi as the seasons went on. He began as a wheeler dealer, con-man. This is a trait that may have stuck with him, but the deepening of Quark pushed this somewhat into the background.
He was shown to be a man with a heart, one with an inconsistent approach to the way he deals with others. There are times when he works as hard as he can to screw over those around him and then there are times when he goes out of his way in a semi-heroic act. One of his first examples of being a good person comes in his refusal to out Pel as a female, once she is discovered to be posing as a man to make profit.
Quark is a Ferengi with a good heart, though he tries to hide that. Coming to the close of Deep Space Nine though, he is more openly a good person, willing to help and support others - even if his drive to make profit hasn't altogether disappeared.
His business is going strong in Star Trek Picard and it remains to be seen if he will return as a dealer for the La Sirena to trade with.
