Yu-Gi-Oh!, Season 3: Enter the Shadow Realm

Odion:
Release my master now!

Yami-Marik:
Your master is almost gone! I'm afraid you've come too late. I've taken his body and the Shadow Realm is about to take his soul! The Marik you once knew will soon be extinct, Odion. He'll no longer be able to hold me back!

Odion:
That's not true. I've returned to ensure that your gentle spirit prevails.

Yami-Marik:
THAT'S ENOUGH! [takes out the Millennium Rod and aims a blast at Odion]

Ishizu:
Odion!

Odion:
[straining] Master Marik! Fight the evil within. We've conquered your wicked side before and we can do it again!

Yami-Marik:
SILENCE!

Ishizu:
Hold on!

Odion:
I'm fine, Ishizu. Please, Master. You have the power to stop your dark side. Remember, you're the one that created him! And you can destroy him!

Marik:
He's right! I can destroy him!

Yami-Marik:
I've heard enough! Now take this! [starts going loco as his good side starts to regain control]

Yugi:
Hey, look, do you see what I see? Marik is freaking out up there!

Yami-Yugi:
I see.

Yami-Marik:
What is going on?!

Marik:
I'm regaining control of my life!

Odion:
Fight his evil with all your might, Master Marik! Let your Tomb-keeper's heritage give you strength!

Yami-Marik:
[screaming] I've come too far to lose my grip now! I AM THE TRUE MARIK! And I will not be overpowered by my weak side!

Marik:
If you can hear me, Pharaoh, attack now!

Yami-Yugi:
No, Marik!

Marik:
Please, Pharaoh! I can't hold on much longer! I need your help to banish my dark half forever! I'm sorry for everything I've done to you and your friends. As a Tomb-keeper, I was raised to serve you, but I always resented this task. This resentment turned to hatred and my dark half was born! What I did was wrong, but I'm ready to take responsibility for my actions and correct the wrongs I've committed!

Odion:
[relieved] Well said, Master. I've waited so long to hear those words.

Marik:
Please, Pharaoh! Attack! It's the only hope for my survival!

Yami-Marik:
No, don't listen to him!

Marik:
YES! You must attack me to save mankind! Please! But hurry, I can't hold him back much longer!

Yugi:
[worried] We can't attack him! It's just too risky! The force of our attack could send him straight to the Shadow Realm!

Yami-Yugi:
Yugi… we have no choice. We must trust him!

Marik:
Pharaoh! PLEASE! ATTACK ME NOW! IT'S THE ONLY WAY!
