For the roller coaster at Six Flags America, see Batwing (Six Flags America).

A batwing on Viper at Six Flags Magic Mountain.

A batwing is a heart shaped element that inverts riders twice. It is made up of a sidewinder, followed by a reverse sidewinder. This inversion is the inverse of a cobra roll.

The element was first used on Orient Express, where it was called a "kamikaze curve". Orient Express was demolished after the 2003 season.

On later Arrow Dynamics roller coasters, such as Great American Scream Machine at Six Flags Great Adventure, it is known as a boomerang, however on Bolliger & Mabillard roller coasters, such as Montu at Busch Gardens Tampa and Afterburn at Carowinds, it is known as a batwing.

Elements similar to a batwing are the bowtie and the pretzel knot.
