Dr. Smith is one of the main characters in the Netflix series Lost in Space.


A mysterious woman and an enigmatic x-factor. She is part-villain, part anti-hero, compelling, charismatic and treacherous. As a stowaway and possibly a saboteur, she is definitely a born trouble-maker.She's unnervingly calm during the disaster that results in everyone becoming lost in space. Stranded along with Don West and the Robinson family, she's a master manipulator, always working one side against the other, thinking three moves ahead to achieve her mysterious ends.

We see in a flashback, that she stole the coat from the real Dr. Smith. This revealed to us that her real name is not Dr. Smith.
