'Legion' Season 3 Welcomes Time Travel and Charles Xavier

There's no time like the present. Or the past. Or the future. 

The third and final season of "Legion" will debut on FX on Monday, June 24 at 10:00 pm ET/PT. Watch the official trailer above, and check out the Season 3 poster below!

The third season is going to be a real power trip. As seen in the trailer, David Haller, now a leader of a psychedelic commune that worships him, recruits a time traveler, Switch, to help him save lives, starting with his own.

Self-dubbed the 'Magic Man,' David helps his followers open their minds. However, Amahl Farouk and Syd are determined to kill David. David believes he's a good person but Syd reminds him that he "ends the world."

In addition to the return of David, Farouk, and Syd, the third season trailer showcases an upgraded Ptonomy Wallace, Kerry Loudermilk, Cary Loudermilk, Clark DeBussy, and Lenny Busker.

But more importantly, we get our first glimpse of Harry Lloyd as Charles Xavier in what appears to be an earlier model of Cerebro. 

To see how the series comes to a close, catch "Legion" Season 3 when it returns on June 24 on FX!
