《Born To Fight》是UNIQ演唱的歌曲，由Jarah Gibson、Def Jef填词，DK、MRey、Hyuk Shin谱曲。

好莱坞真人特效版动作冒险电影《忍者神龟：变种时代》主题曲《Born To Fight(为战而生)》。歌曲《Born to Fight（为战而生）》由Justin Bieber制作团队Joombas Music Group为UNIQ量身打造，将时下最热火的嘻哈、摇滚、电子元素融为一体，整体极富律动。UNIQ也凭此曲成为派拉蒙影业史上最年轻的主题曲演唱者。

歌词以堕入人间的城市英雄为概念，表现出时刻准备为正义而战的英雄形象。“将我击倒我也会再次崛起，永不放弃的人不会轻易言败。”主题曲歌词奋发向上，旋律动感明朗，展现了年轻人昂扬不屈、积极进取的态度，充满正能量，与电影的气质十分吻合。

Born to Fight（歌词）

Knocking me down doesn’t mean that I wont get up

you know it’s hard to beat something that just wont give up

steady throwing dirt I just tweak it in the track

threw me to the wolves came back leading the pack

testament to my passion and hustle

rain on my parade and I’m splashing in the puddles

throwing shade means nothing I was born in the dark

made it out the jungle just a walk in the park

Winning aint easy ask any loser

need steady aim you can ask any shooter

you aint the homie b stop friggin' bro in me

knowing about me aint the same as knowing me

We come from the dark and yet we walk in the light

heroes are made and always down to ride

We are born to fight we are ninja turtles

(Let's all unite, let's fight fight, let's fight fight, let's all unite)

We are born to fight we are ninja turtles

(Let's all unite, let's fight fight, let's fight fight, let's all unite)

You gotta throw them daggers if you wanna be an MC

choppin' up opposition screaming TMNT

When you fight for underground you fighting a 100 rounds

invaders in trouble now the lightning is coming down

Completely unseen shadows in the night

my lights are on beam my sights are on green

Hit you with nu-jitsu flow so cold

you thinking the flu hit you them foes don't know

We come from the dark and yet we walk in the light

heroes are made and always down to ride

We are born to fight we are ninja turtles

(Let's all unite, let's fight fight, let's fight fight, let's all unite)

We are born to fight we are ninja turtles.

(Let's all unite, let's fight fight, let's fight fight, let's all unite)

We stay winning let's go get it

We are born to fight we are ninja turtles

(Let's all unite, let's fight fight, let's fight fight, let's all unite)

We are born to fight we are ninja turtles

(Let's all unite, let's fight fight, let's fight fight, let's all unite)
