Lyrics
When I was the Lion Guard's fiercest
I took most patrols on my own
So when I met this strange lion
I had no fear of being alone
He said he had wisdom and power
And the most powerful should be king
With help from me and my roar
He and I could rule everything
I found his idea intriguing
Though the most powerful lion was me
But the strange lion was scheming
And had a friend that I didn't see...
That's how I got my scar
From when I led the Guard
The lion would cure the snake's venom
As long as I did what he said
But I lost control and in rage
I roared and destroyed them instead
I expected to be praised near and far
For stopping that traitorous thing
But Mufasa just nicknamed me Scar
Then I knew that he shouldn't be king
That's when I became Scar
From when I led the guard
My first plot for vengeance
Was foiled when I lost the Roar
My second plan later succeeded
Mufasa was the king no more
If it wasn’t for that miserable Simba
I would’ve ruled Pride Rock to this day
But now, it is time
For Simba and Kion to pay
That's why I still am Scar
From when I led the guard
Oh-oh
That's why I still am Scar
And that’s why I'll destroy the guard!
