Leonard Snart

Leonard Snart is a character on CW series Legends of Tomorrow, based on the DC comics character and introduced to the franchise on The Flash.

Character
Snart is a smart, calculated, seemingly snide and cold man. His father went to prison when he was around 6 years old, and upon his return started beating Snart and his sister, Lisa. Having been taken on jobs with his father, Leonard became a criminal himself (as did his younger sister) and he went to juvy when he was 14. He confesses to Sara that he thought he would die when being beating in there, but was rescued by Mick; this cemented their partnership.

Snart agrees to take up with Rip Hunter in order to steal from various epic eras in time and possibly destroy his records. It turns out his biggest aim is to change his own past, namely his father's violent disposition as a result of being imprisoned. Snart and Rory keep their own aims in sight at first, but eventually find affinity for their "new crew", the team. However, this development alters their partnership, as Mick is still looking to steal while Leonard starts re-evaluating his life as part of the team. When stuck in 2046, Mick wants to stay in the dystopian future, while Snart would rather stay with the Legends. A rift forms between them and when Mick betrays the team to Time Pirates, Snart puts his allegiance with the Legends.

Snart tells the team he "took care" of Mick, but really leaves him behind. When Mick shows up as Kronos, Snart tells him he was always going to return for him.
