Roar

Roar (trademarked as ROAR) is the name of a wooden roller coaster at Six Flags America located near Upper Marlboro, Maryland. There were originally two roller coasters; the first and current ride was built in 1998 at Six Flags America, and a second ride was built in 1999 at Six Flags Discovery Kingdom. Both rides were designed and built by Great Coasters International (GCI). In 2015, Discovery Kingdom announced the retirement of its version of Roar, which Rocky Mountain Construction later renovated and transformed into The Joker, a hybrid roller coaster.
