Katy Perry burned her blue wig, laid her "California Gurl" to rest and turned an adorable kitten into a ferocious animal. On Friday (August 9), she continued to put the past behind her.

In the latest teaser for her upcoming single, "Roar" — the first off her October 22 album Prism — Perry gives fans a longer snippet of the uptempo, power-pop track, which is set to premiere on Monday.

In the clip, titled "Satin Cape," the "Wide Awake" singer seductively, yet mischievously gazes at the camera as she walks into a recording studio. Perry then gets behind the microphone, puts headphones on and takes one long look at the camera before it cuts to the song title and the track fills our ears. "I am a champion, you're gonna hear me roar," Perry declares.

It's worth noting that Perry is rocking a considerably darker new look in the recent clips, including a cut-off striped sweater, skirt and choker. In the new 45-second tease, fans get to see the entire outfit, which finishes off with thigh-high stockings, combat boots and the same jean jacket she sports in her Lisa Frank-inspired single cover art.

Perry reportedly worked with producers Dr. Luke and Max Martin and longtime collaborator/songwriter Bonnie McKee on "Roar." And McKee recently told MTV News she is "really excited for the world to hear it because she's ... taking a new approach.

"And I don't want to say too much about it, but it's definitely different. It's definitely a little more mature than the 'California Gurls' of yesterday."

Fans won't have to wait much longer: "Roar" will be released in full on Monday.
