Zoroark: Other pokemon walk through life where you prefer to skip
And other pokemon watch their step where you'll most likely trip
Sure, your hair's not perfect,
And there'sーwhat's that on your shorts?
Yeah, you're kinda talkative
With freckles on your nose.

But you're you...you-you,
And that's what makes me smile.
You're you...you-you
So stay that way awhile.

lucario: Oh, zoroark...

zoroark: You don't have to say a thing, I know the way you feel.
Your face is like an open book; so honest true and real.
Other pokemon lie and cheat,
One push may come to shove.
Your heart doesn't work like that,
So you're the lucario I love.

You're you...you-you,
That's how I hope you stay.
You're you...you-you.
But anyway, that's all I've got to say.
