Challenger的歌詞作者是Perfume，以下是Challenger的歌詞：
Take off your helmet, you're feeling so heavy
Get up, it's time to fight
And you know you're the champion
You're the one who's gonna change the game
You're the one who's gonna break the chain
You're the one who's gonna make it right
You're the one who's gonna make it all the way
Yeah, we're here to take it to the limit
We're here to break the mold
And we're not gonna stop until we win
'Cause we're the challengers
You know you got the power, you got the speed
You got the fire in your feet
And you know you're the fighter
You're the one who's gonna change the game
You're the one who's gonna break the chain
You're the one who's gonna make it right
You're the one who's gonna make it all the way
Yeah, we're here to take it to the limit
We're here to break the mold
And we're not gonna stop until we win
So let's get loud, let's get loud, let's get loud
Challengers, we are here to stay
We are here to take over the world
We are here to make a change
We are here to make a difference today
Yeah, we're here to take it to the limit
We're here to break the mold
And we're not gonna stop until we win
Yeah, we're the challengers, we are here to win.
