This is how Princess Atta defeats Umarak goes in
[Umarak arrives at the portal to the Shadow Realm on top of the Black Volcano in the Black Crater in the Region of Stone]
Umarak the Hunter: The door to the Realm of Shadow. At last, I can get away.
Princess Atta: I don't think so.
[Umarak turns to see her]
Umarak the Hunter: I'm surprised you came here alone.
Princess Atta: Well, I'm not technically alone.
Umarak the Hunter: Really?
Princess Atta: Really.
[Atta snaps her fingers and the Toa show up]
Umarak the Hunter: Toa!
Tahu: You tried, Umarak.
Onua: But you should try harder.
Lewa: At this rate, your plan's not going so well.
Gali: It's gonna be foiled eventually.
Pohatu: By us.
Kopaka: Together as one.
[The Toa bring out their weapons and new Toa, Attuna, joins them]
Umarak the Hunter: And who is this?
Attuna: I'm Attuna. A Toa in training. [brings out her Ant Blade]
Umarak the Hunter: You wish to defeat me with that?
Attuna: I'd do anything to serve my creator, Princess Atta.
[Attuna and the Toa charge]
Umarak the Hunter: You should've took my deal. [pins Atta against a wall with his bow] Now you will spend the rest of your life living in the Shadow Realm.
[Atta stops and thinks of an idea]
Princess Atta: I got news for you, Shadow Man. It's not your deal, it's mine. [kicks him off]
Umarak the Hunter: At least I still have this. [sees his talisman is gone] My talisman! Where's my talisman?
Princess Atta: Right here. And like before, in the end, it's always the Toa that get the victory. [smashes it to the ground]
Umarak the Hunter: [horrified] No. No. Duh. How am I ever gonna pay back my debt?
