"Kick Ass (We Are Young)" is a song by English singer Mika and Moroccan-Swedish record producer RedOne released as a single from the soundtrack to the film Kick-Ass.

He also praised the collaboration saying it "actually works remarkably well, creating a pop stomper that's empowering, oh-so-contemporary and packed with personality".

[3] Contemporary music website Popjustice also gave the song a positive review, after what was seemingly going to be a negative one, they ended it with "Guess what – 'Kick-Ass' is also AMAZING".

[5] He begins to sing and as he does, the words of empowerment in the lyrics and his finding of an issue of the "Kick-Ass" comic inspire him to run for the rooftops and wail the chorus to the sky, now dressed in a slightly more superhero version of his "original persona" outfit.

In Italy, it peaked at number five and it was certified platinum by the Federazione Industria Musicale Italiana, for digital sales exceeding 30,000 units.
