Detailed 'Legends of Tomorrow' Season 4 Synopsis with Constantine joining the team

Matt Ryan's John Constantine is officially hopping in the Waverider with the Legends next season as a series regular on Legends of Tomorrow.

The CW released a new detailed synopsis for Legends of Tomorrow's fourth season. The synopsis gives a bit of more detail about what Constantine's got to do with the team this season.

Season 3 ended with the Legends went to relax on the beaches of Aruba when Constantine arrived to inform them that while they may have defeated Mallus, they may have created a much bigger problem. The following season will revolve around all kinds of magical creatures called "Fugitives" and how they act upon it.

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 (Caity Lotz) and her team join Ava Sharpe (Jes Macallan) and the Time Bureau to help clean up the last few remaining anachronisms. The job seems straightforward enough until Constantine (Matt Ryan) 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 (Brandon Routh), hotheaded ex-con Mick Rory (Dominic Purcell), rebellious totem-bearer Zari (Tala Ashe), and heartbroken historian-turned-superhero Nate (Nick Zano) as they set out to save the world – and their legacy. It’s the familiar fun of the Legends time-travelling across historical events and encountering famous figures with an added shot of magical craziness!
