Chameleon is the fifth studio album by German power metal band Helloween, released in 1993.

The album contains four singles: "When the Sinner", "I Don't Wanna Cry No More", "Windmill", and "Step Out of Hell".

The album received negative reviews both critically and commercially, and vocalist Michael Kiske and drummer Ingo Schwichtenberg were fired after the subsequent promotional tour.

The band were lambasted with debts of the amount of two million Deutschmarks, and were just trying to get rid of that and thought that if they made the album commercial it would work.

Grapow was replacing Kai Hansen, and tried to write songs with a heavy metal direction, which he did on 'Pink Bubbles Go Ape'.

Helloween recorded the successful 'Keeper' albums and then Hansen left, and they tried to do totally different kind of music.

[7] Bass player Markus Grosskopf stated that 'Chameleon' captured the time and the mood that the band was in, so he doesn't see it as a mistake.
