Kratos is the ever so brutal protagonist of the God of War series. His appearance is iconic and he has a very in depth past that plays a key role in how the entire series plays out. Kratos began as a Spartan warrior of the greatest skill. He had a wife and an infant child in Sparta. Infact he was so skillful in the art of war that he soon became a captain of the Spartan army. The Spartans led many successful and brutal campaigns that tore Greece apart which soon made Sparta the biggest power in the Mediterrenean. No army was big enough or strong enough to bring down the power of Spartans until one army challenged the Spartans. A horde of barbarians led by theirBarbarian King attacked the Spartan army. They were flaming in rage that saw them tear down countless Spartans, their numbers were so great that the Spartans were panicking as to whether they could win this battle or if they were all to be killed. As the last Spartans met their end the Barbarian King approached Kratos and upon the brink of defeat, Kratos called out to the God of war, Ares. He asked Ares for his aid in this time of need but at a cost. If Ares was to help him this time, Kratos's life would belong to him. With clouded judgement, Kratos hastily accepted and the God of war descended from the skies to massacre the entire barbarian army. It was the battle that would change Kratos forever.
Ares knew of Kratos's skills in combat and now that he was under his control he ordered Kratos to lead his army in many battles. The battles were unjust and only served to kill the innocent but Kratos had no choice but to comply as he was now completely under Ares's control. It was one particular raid on a village that would scar Kratos for life. As he slaughtered the villagers and burned the buildings he entered a temple where villagers were taking refuge and slaughtered them all but when he looked back at who he had killed he realised he had slain both his wife and child. As anger burned inside him at that moment, the ashes of the burning village engulfed him and seared his skin to reveal a much paler, whiter layer. From then on he became the Ghost of Sparta...
 Role In God of War
The first God of War game deals with Kratos quest to kill Ares, the God Of War, who had so cruelly tricked and enslaved him in the years prior to the game. In return for killing Ares, Kratos pleads with Athena to release him from the horrors of his past, a request which Kratos ostensibly believes is granted. His quest starts off on the Aregean Sea where he is charged with slaying the Hydra, and leads him into Ancient Athens. Kratos hunt for Ares takes him through the perilous Desert Of Lost Souls and encounters with the Sirens, before finally coming across Pandora's Temple. After gaining Pandora's treasure, which would give him the power to kill a God, Kratos is once again attacked by Ares, who casts him into the depths of Hades. However, Kratos foils Ares plan and escapes from Hades, before unleashing the power of Pandora and finally encountering and slaying Ares in a brutal battle overlooking Athens. The game ends with Kratos awarded the title of the new God Of War by Athena - however, Athena can only forgive the sins of Kratos, and is unable to remove the visions of Kratos bloody past which continue to haunt him. The game therefore, while coming to a satisfying conclusion for the gamer, makes it clear that Kratos is not satisfied with his treatment by the Gods. The betrayal which Kratos feels at the end of God Of War I would then be built upon in God Of War II.
 Role In God of War II
God of War II picks up where the first game left off, with a disenchanted Kratos becoming an even more bloodthirsty and brutal God Of War than his predecessor Ares ever was. Despite pleas from Athena for Kratos to moderate his behaviour, he ignores these pleas and proceeds to attack Rhodes. Despite encountering The Collossus, a giant statue brought to life by Athena in an attempt to stop Kratos, he overcomes this obstacle through the use of the Blade Of Olympus. However, in order to use the Blade Of Olympus, Kratos was tricked by Zeus into transferring all of his Godly power into the blade. While this meant that Kratos was successful in destroying the Collossus Of Rhodes, it also rendered him mortal. Kratos is hit by the falling hand of the Collossus, weakening him severely. During this time, Zeus comes to Earth in order to kill Kratos and end his reign as the God Of War, uttering the words - "You will never be the ruler of Olympus". Kratos soul descends into Hades - however, he is rescued by the Titan Gaia, and with her help, fights his way out of Hades and returns to Earth. The only way for Kratos to reverse history and to find a way to kill Zeus would be for him to seek out The Sisters Of Fate, and use their thread of time to return to the moment of his betrayal. The vast proportion of the game from here on is dedicated to this storyline. Once Kratos has found - and killed - the Sisters Of Fate, he returns to the time when Zeus betrayed him. After a lengthy battle, Kratos prepares to strike the deciding blow against Zeus - however, Athena sacrifices herself for her father Zeus, who then retreats to the safety of Mount Olympus. It is then that we learn that Zeus is Kratos father, and fears the fulfilment of a prophecy which stated that he would be killed by his son. Kratos, more hell-bent than ever on gaining revenge against Zeus, once again uses the thread of time, this time to return to the war between the Gods and the Titans. Kratos saves the Titans from their defeat, and with their help, proceeds to scale the cliffs of Mount Olympus. The game ends with Kratos uttering the line - "Zeus, your son has returned!". While Kratos plays even more of an anti-hero in God Of War II, it becomes clear as the game goes on the level of betrayal that Kratos has had inflicted upon him by the Gods. The game's ending makes it clear that God Of War III will finally see Kratos getting his revenge.
 Role in God of War: Chain of Olympus
Chains of Olympus is set before the first two games and tells of his hardship before he attempted at becoming the God of war. At this time, Kratos is still serving the Olympians and carrying out their gargantuan tasks. Firstly he is sent to the city of Attica that is under siege by the Persian King and his hordes of soldiers. With them they have bought the treacherous Basilisk. Kratos soon ploughs his way through them cutting them off at the Persian King who tries to offer Kratos riches in exchange for his submission, but Kratos brutally declines. After slaying the Basilisk moments later the world is suddenly took by surprise as darkness engulfs the entire planet. Confused by this Kratos asks if it is the work of the Gods but is told by them that the world is in grave danger, the sun god, Helios has been stolen from the sky and is in the hands of the titan, Atlas. Without any sun to repel the darkness, Morpheos, the God of slumber has arisen and sent the world into an eternal sleep and rendered the olympians powerless. Kratos plunges into the underworld in order to rescue Helios, he finds the only way of doing so is by restoring the fire in his fallen chariot. Finding the source to light the flames leads Kratos across the underworld where he ecounters many adversities including the mysterious, Charon, boatman of the river styx who casts him into the pits of Tartaru where he meets, Persephone, the tragic wife of Hades. Meanwhile during the entire ordeal Kratos has been troubled by the haunting sound of a distant melody and soon finds out that it is no other than his own daughter, Calliope. After igniting the flames, the horses lead him to their master, Helios. As he reaches his destination he questions whether he is more satisfied serving the Olympians and saving mankind or whether he would wish to be with Calliope. As he stays with his daughter his life slowly drains from him and so does his wounds and guilt, the exact thing he wanted; to be rid of his bloody past. However when he comes around he realises that mankind needs him so after leaving the sobbing Calliope, knowing he will never see her again, he races towards Atlas and Persephone for the final showdown. In doing so he becomes what he was before, the ghost of Sparta. Afters slaying the deceitful Persephone, he binds Atlas to the curst of the earth with Atlas's chains. Atlas foreshadows the story as he tells Kratos that the Olympians will betray him and that he will regret stopping Atlas. Kratos ponders on this thought be before he knows it he is shot into the sky by the sky chariot and the world is saved but then descends back through the sky where he passes out and is aided by a soft landing.
Kratos has pale, white skin, a bald head and small goatee beard. He wears a robe around his waist, boots and two wristbands in the first game. He is bare chested but this leaves more room for his iconic warpaint to be applied. The warpaint coils around his entire body and also stipes across his head making him look even more fearsome than without. He carries two blades that are attatched to chain otherwise known as the Blades of Chaos. These are Kratos's signature weapon and will be the weapon mainly used in the game. At the end of the first game when Kratos becomes the God of war he is replaces his robes for armour which covers every thing but his head.
