Trollhunters: Rise of the Titans

Master wizard Douxie Casperan and former Arcane Order member Nari are ambushed by the arrival of the Order in a moving subway train, while former Trollhunter Jim Lake Jr. & his girlfriend Claire Nunez accompany the two. Jim is wounded in a battle against Bellroc, the leader of the Order. Toby Domzaski, Jim’s best friend, accidentally snaps the train’s brakes, causing the train to be unable to stop, and complicating a plan to use 'trifurcate radiation' to render the wizards powerless. When the train is about to go off-track, Douxie conjures magical train tracks, after the radiation beam is broken. In a last ditch effort, Douxie switches bodies with Nari, leaving her in his body, with the Order unaware about Douxie’s conjure. Nonetheless, the order flees with Douxie (in Nari’s body).
