Car fanatic Philip Glenister teams with designer Ant Anstead on a mission to find classic cars in not-so-classic shape, fix them up and then auction them off. Glenister finds vehicles that he can get for the right price and brings them into the shop for Anstead to restore. Since Glenister gets to know each seller during the bargaining process, he uses stories about the car as inspiration to help inform Anstead's overhaul. After the front-to-back transformation is complete, the guys take the car for a spin. At the end of the season, the finished cars are sent to a public auction to see if all of the hard work pays off.

Cosplay -- the practice of dressing up as characters from movies, books or video games -- is a popular activity in the sci-fi community. People transform themselves into pop culture-inspired creations, often with an emphasis on anime characters. Usually, it's just for fun and playful contests, but on "Cosplay Melee," the perfect costume can be worth $10,000 to a cosplayer. Each episode sees four contestants creating full costumes and character origin stories, then hitting the runway in an attempt to impress the judges, who are world-class cosplayer LeeAnna Vamp and costume creator Christian Beckman, by looking -- and acting -- the part. Whoever the judges feel most embodies the character is proclaimed the winner and earns the grand prize. Actress Yvette Nicole Brown ("Community") hosts the show that Syfy says compares to reality show "Face Off" but "with a triple dose of adrenaline."

Aspiring artists compete to bring their wildest beast to life.
