Season 4 (DC's Legends of Tomorrow)

DC's Legends of Tomorrow was renewed for a fourth season by The CW on April 2, 2018. It will premiere 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, fairytales, 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!

Confirmed new characters

 * Ali: A young woman who is searching deeply for her mission in life. A mega-intelligent and sharp as heck person, “Ali” tends to sometimes be a little aloof and being too distracted by her own imagination as well as romantic impulses. She loves YA literature as well as fantasy novels hence her hunger and curiosity for adventures. Despite her disappointment with the state of the world, “Ali” continues to keep an optimistic head as much as possible with any situation that she faces. “Ali” also has a deep love for animals as she believes each animal has a purpose to fulfill on our planet.
 * Hank Heywood: While he is loved by many, his son Nate is not one of them. Their relationship is a very mixed one as Hank is always on his son’s back for not doing more with his life. Having served in the military, Hank is now working for the Department of Defense. Carrying a Woody Harrelson-y charm, Hank takes traditional values very seriously such as patriotism and sacrifice. But he isn’t being a dick about his beliefs and while Nate may have had his list of failures in life; Hank loves his son as much as a father possibly could.
