Snake: "Dude...this guy looks like he wants to murder me or something."
Otacon: "Snake, that's Kratos! He is considered to be the strongest warrior. And if you thought Ganondorf was dangerous, just take a look at this guy!"
Snake: "Hmm...muscular body, and...that's all I've got."
Otacon: "Well, Snake. Kratos had a tough life. After becoming a servant of Ares, he became bloodthristy and killed tons of civilains, and of course, accidently his wife and daughter. And since then, Kratos became the Ghost of Sparta and decided to serve the gods in order for them to forgive him and his sins."
Snake: "Hmph. That's pretty tough for him."
Otacon: "Yeah, well, after ten long years, Kratos finally got his revenge on Ares by killing him. Despite having his mission completed, the gods could never take Kratos' nightmares. But, the gods decided to let Kratos become the new God of War. Since his nightmares wouldn't be taken, Kratos has taken his rage on innocent cities, and that made the gods really unhappy. So, the gods betrayed him, and Kratos has decided to get revenge on them, and those who get in his way."
Snake: "Whew...I guess I'm the one that's in his way."
Otacon: "Oh, Snake, get this! Kratos has been killed a couple times. But, surprisingly, he just comes back from the Underworld!"
Snake: "A mortal man coming back from the dead?"
Otacon: "Don't worry. He's not a zombie. He's still human."
Gaia: "Hmmm...this is a bit odd, Kratos. You seem to be fighting yourself. Perhaps this might be the work of Zeus and the gods. I know that the real Kratos, which you are, will be able to defeat this imposter. But be careful of this faker's moves. He might try to look like a mirror. Find his weak point, and you will have the upper hand, Kratos."
As Kratos journeys to kill Zeus, he steps into a portal that was made by Zeus, as the King of the Gods hoped that it would trap him for all eternity. Kratos wakes up as he realizes he is in another world called the World of Trophies. To find a way back to his own world, Kratos has to fight myterious fighters in this world in order to get stronger in his coming up fight against Zeus, while also hoping that Athena will help him find a way out.
Kratos defeats Sora, and stares at the trophy form of the keyblade warrior. Kratos wonders why the opponents in this world turn into trophies after being defeated. But he decides to forget all about this and goes into a portal formed by Athena that leads back to his world. Thinking of what he has done to the smashers that he had defeated, Kratos knew what was right for him, and runs to return to Mount Olympus and kill Zeus.
