In Scooby-Doo 2: Monsters Unleashed, Scooby and the gang lose their cool – and their stellar reputation – when an anonymous masked villain wreaks mayhem on the city of Coolsville with a monster machine that re-creates classic Mystery Inc. foes like The Pterodactyl Ghost, The Black Knight and The 10,000 Volt Ghost. Under pressure from relentless reporter Heather Jasper-Howe (Alicia Silverstone) and the terrified citizens of Coolsville, the gang launches an investigation into the mysterious monster outbreak that leaves Shaggy and Scooby questioning their roles in Mystery Inc. The ever-ravenous duo, determined to prove they’re great detectives, don a series of far-out disguises in their search for clues. Meanwhile, brainy Velma (Linda Cardellini) becomes smitten with a key suspect, Coolsville Museum curator Patrick Wisely (Seth Green), as macho leader Fred (Freddie Prinze Jr.) and image-conscious Daphne (Sarah Michelle Gellar) attempt to determine the identity of the Evil Masked Figure who is unleashing the monsters in an attempt to take over Coolsville.
