What is the title of the 2002 The Powerpuff Girls Movie theme song by Lazlo Bane?

The 2002 The Powerpuff Girls Movie theme song by Lazlo Bane is “Signal in the Sky (Let's Go).”

Lazlo Bane recorded the song for the theatrical film based on the Cartoon Network series. The track appears as the movie’s prominent theme and reflects the band’s alternative-rock sound while matching the film’s superhero focus. Its title combines a call to action with the phrase “Let’s Go,” making it especially suited to the fast-moving opening and promotional identity of the movie.

The film expands the television origin story by showing how Professor Utonium creates the girls and how their early attempts to help Townsville lead to conflict. The song belongs specifically to the movie’s soundtrack and should not be confused with the television opening theme performed by Bis.

That distinction is useful because both pieces are associated with the franchise but come from different productions. Bis performed the original series opening, while Lazlo Bane supplied the movie theme. The song title is sometimes shortened in informal references, but the full credited title is “Signal in the Sky (Let’s Go).”
