Samurai Jack Theme

The Samurai Jack Theme is the theme song for the animated series Samurai Jack. It was performed by Will.i.am.

The song appears in the intro sequence of every episode (apart from the first episode and the fifth season) and appears in every episode during the end credits.

Opening monologue (Aku)
In the first four seasons, Aku starts narrating a monologue before the actual theme song plays.

Long ago in a distant land, I, Aku, the shape-shifting 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!

Opening monologue (Jack)
In Season 5, Jack narrates a monologue instead of Aku. The theme song itself is omitted from the intro but still plays in the outro.

''Fifty years have passed, but... I do not age. Time has lost its effect on me.''

''Yet, the suffering continues. Aku's grasp chokes the past, present... and future. Hope is lost.''

''Got to get back — back to the past... Samurai Jack.''

Main theme song (Will.i.am)
This song plays immediately after Aku's monologue, but not Jack's. It also plays again during the end credits.

Gotta get back, back to the past, Samurai Jack!

Watch out!

Gotta get back, back to the past, Samurai Jack!

Jack, Jack, Jack, Jack, Jack!
