Overkill is an American thrash metal band, formed in 1980 in New Jersey. They have gone through many line-up changes, with singer Bobby "Blitz" Ellsworth and bassist D.D. Verni remaining from the original lineup. Along with Anthrax, whose one-time lead guitarist Dan Spitz was also an early member of Overkill, the band is one of the most successful East Coast thrash metal bands, and they are often called "the Motörhead of thrash metal". The band has a notable mascot named "Chaly", a skeletal bat with a skull-like face, horns, bony wings and green eyes. Chaly has appeared on most of their album covers.
