Battle Against A True Hero (Undertale)

You think you're someone to fight with courage
And when you see me, you feel a great tremor
You think you can beat me but you never will
True heroes will never fail

Heroes like me fight until the end
And to win they will always have courage
Training with effort and sweat
And when they lose, lifting their spirits

Always strong and standing they must be
To overcome and never make mistakes
Fighting teaches much more
Than killing just for the sake of killing!

You are a rival
Very strong I know
But you won't be able
To beat me here
You endure

Every blow hurts
But you persist
And you want to win!
You are bold
Determined you are
You want power
To kill
I won't let
You pass me
Because if I lose
You'll laugh!

I just want to see you fall
But you don't want to lose
That pride you have in you
Will be what makes you die!

A true hero fights until they can't anymore
And if you die battling, you did everything very well
Never get depressed, there will always be a solution
Because heroes won't lose

A true hero fights until they can't anymore
And if you die battling, you did everything very well
Better get ready because this battle will end
True heroes will win
