Season 4 (DC's Legends of Tomorrow)

"We didn't screw things up for the better this year. We screwed things up for the more magical."

- Nate Heywood

DC's Legends of Tomorrow was renewed for a fourth season by The CW on April 2, 2018. It premiered on October 22, 2018.

Synopsis
After defeating the demon Mallus by cuddling him to death with a giant stuffed animal named Beebo, the Legends are ready to ease off the gas. Sara and her team join Ava Sharpe and the Time Bureau to help clean up the last few remaining anachronisms. The job seems straightforward enough until Constantine arrives to inform them that, in solving one major problem, they have created another, much larger one. When the Legends let time crumble in order to release and defeat Mallus, the barrier between worlds softened. History is now infected with "Fugitives" – magical creatures from myths, fairy tales, and legends. Having been expelled throughout time by people like Constantine, these Fugitives are now returning to our world in droves and making a real mess of things. As the Time Bureau is distrustful of and ill-equipped to deal with magic, the Legends must team up with everyone's favorite demonologist to set history back on track.

Sara and Constantine are joined by compassionate inventor Ray Palmer, hotheaded ex-con Mick Rory, rebellious totem-bearer Zari, and heartbroken historian-turned-superhero Nate as they set out to save the world – and their legacy. It's the familiar fun of the Legends time-traveling across historical events and encountering famous figures with an added shot of magical craziness!
