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

Marik:
[to Odion, still unconscious in the bed; voice-over] Odion, can you hear me? It's me, Marik. My dark side grows stronger as I slip into the shadows, and before I'm gone forever, I wanted to say I'm sorry. You've done nothing to protect me since the day I was born, and I've repaid you with anger and disrespect. I wish I could take back everything, but now it's too late. The evil within me is about to prevail. The very evil I created out of my own hatred now threatens to destroy me! And once he gains the Pharaoh's power, the entire world will pay the price. You were there the day my dark side was born, the day I received the tomb-keeper's initiation. You were always loyal to me, Odion. Even when I betrayed the tomb-keepers and abused the ancient scriptures for my own selfish purposes, you never left my side. Now I understand why you stood by me, even though you knew what I was doing was wrong. It's because you were the only one who could control the evil within me. But when you were hurt, my wicked side took over. [slowly starts to vanish] Now there's nothing left for me to do. I'm drifting away while his power increases. Goodbye, Odion. I'll never be able to repay you for all you've done. I'm sorry. [disappears]
