SAMURAI HARDBEAT

Long ago, in a distant land...
I, Aku, the shapeshifting master of darkness...
Unleashed an unspeakable evil!
But a foolish samurai warrior
Wielding a magic sword
Stepped forth to oppose me
Before the final blow was struck
I tore open a portal in time
And flung him into the future
Where my evil is law
Now the fool seeks to return to the past
And undo the future that is Aku!
