After the departure of “iCarly,” Nickelodeon returns with the new live-action comedy “Marvin, Marvin” (7:30 p.m. Saturday). Lucas Cruikshank, famous for his YouTube character Fred Figglehorn, stars in the title role. He plays a high school outcast. Does he have trouble fitting in because he’s strange, or because he’s from Klooton, a planet threatened with destruction by evil invaders? Think the bad guys will follow him to the cafeteria?
• While we’re on the subject of teenage outcasts, a young warrior sets out to save his father from a terrifying creature otherwise known as the Mind Flayer in the 2012 shocker “Dungeons & Dragons: The Book of Vile Darkness” (8 p.m. Saturday, Syfy). And we all know a mind is a terrible thing to flay.
This is not to be confused with “Dungeons & Dragons: The Wrath of the Dragon God” (5:30 p.m. Saturday, Syfy).
• On the other side of the gender divide, Julie Berman (“General Hospital”) and Justin Bruening (“Switched at Birth”) star in “The March Sisters at Christmas” (7 p.m., Lifetime), an updated holiday-themed variation on “Little Women,” the beloved novel by Louisa May Alcott.
l Along similar lines, Hilarie Burton stars in the 2012 bauble “Naughty or Nice” (7 p.m., Hallmark), about a woman who steals Santa’s secret compendium of children, dividing the good from the bad. Meredith Baxter co-stars.
