New network FXX launches at 7 a.m. Monday, taking several of sister channel FX’s shows with it, including “It’s Always Sunny in Philadelphia,” “The League,” “Legit” and “Totally Biased with W. Kamau Bell.” The network (available in the Washington area on Comcast channel 725, RCN channel 362, DirecTV channel 619 and DISH Network channel 390) kicks off with a marathon of “Parks and Recreation” until noon.

Charlie Sheen is FX’s newest star, so the network takes the opportunity to run a day-long marathon of his old show, “Two and a Half Men” (7 a.m.) — an awkward decision, given that he didn’t leave the series on the greatest of terms.

Cedric the Entertainer joins the syndicated version of “Who Wants to Be a Millionaire” (WJLA at 12:30 p.m.) for Season 12, replacing host Meredith Vieira.

Cartoon Network has a big night of premieres, starting with a new season of “Regular Show” (7:30 p.m.), starring best friends Mordecai, a six-foot-tall blue jay, and Rigby, a hyperactive raccoon. Afterward, the comedy “Uncle Grandpa” (8) debuts, about a magical uncle and grandpa who travels around the world helping people, using a mystical RV as his primary mode of transportation.

If you’re deeply invested in the relationship between “Real Housewives of Orange County” star Tamra and her fiance, Eddie, just a heads-up — the three-part docu-series “Tamra’s OC Wedding” (Bravo at 8) kicks off, chronicling the journey behind the scenes since the couple got engaged last year in Bora Bora. Included: joint bachelor and bachelorette parties in Vegas, along with Tamra’s wedding dress fittings.

James Franco steps up and gets roasted on the “Comedy Central Roast of James Franco” (10), hosted by roast master Seth Rogen and taped in Los Angeles last weekend. Performers including Aziz Ansari, Andy Samberg, Nick Kroll, Jonah Hill and Sarah Silverman line up to take shots at the actor.

Savi decides it’s time to move on from Harry and gives Dom a chance on “Mistresses” (ABC at 9). Meanwhile, the judge finally rules in Karen’s case, but it’s a very surprising verdict.

Andy Cohen rounds up the gang from “Below Deck: Reunion” (Bravo at 10) to discuss all the drama and ridiculous situations from Season 1.
