Unleashed is the ninth studio album by American Christian rock band Skillet, released on August 5, 2016.^[4] The album was announced on May 20, 2016, and a lyric video was released for the track "Feel Invincible" at the same time on the band's YouTube channel.

The band worked with Brian Howes, who previously produced their 2006 album, Comatose, along with producers Kevin Churko, Neal Avron and Seth Mosley. Cooper stated he felt "'really inspired'" before going into the studio to record the music.^[6] Even though he said "'the songs are very aggressive, very in-your-face'", he said the new material is genuine to the Skillet sound they have crafted.^[7][8]

On April 8, Skillet released a preview of a new song, later revealed to be called "Out of Hell", on their social media pages.^[9] On May 20, 2016, the album's title, Unleashed, was announced and is to be released on August 5, 2016, on Atlantic Records.^[10] A lyric video, "Feel Invincible", was also made available.^[11] On May 26, the lyric video and digital single "Stars" was released, along with a preview for another song titled "Back from the Dead".^[12] On July 8, the full version of "Back from the Dead" was made available for purchase online,^[13] followed by "I Want to Live" on July 29.^[14]

John Cooper noted that Unleashed is made up of songs ranging from metal to pop.^[15] Cooper also mentioned that he wanted the songs from Unleashed to be connected both in their lyrics and music.^[4]

The music video for Skillet's first single, "Feel Invincible", was released on June 29, 2016.^[15] The single charted at No. 3 on the US Christian Rock charts and No. 17 at the US Rock charts. WWE announced on July 7 that it had chosen "Feel Invincible" as an official theme for the 2016 Battleground pay-per-view event.^[16] The song has also been chosen as the theme for TBS' ELeague, an eight-week live video-gaming competition that will be broadcast in more than 80 countries.^[17]

John Cooper says the track "represents the album in one facet really well: [Unleashed] is full of crowd-chanting anthems. The album is very exciting to listen to. Driving beats and melodic choruses, whether it's hard rock or leaning toward pop." He also notes that Unleashed is "quite diverse—there are more extreme songs on both sides of the spectrum, meaning harder rock and even metal, but also pop and atmospheric tunes/sounds."^[18]

On August 9, 2017, it was announced that Unleashed would be nominated for a GMA Dove Award in the Rock/Contemporary Album of the Year category at the 48th Annual GMA Dove Awards.^[19] In 2018, the album was certified gold in the United States.^[20]
