O that David Jaffe intended for Kratos to take on the Norse Mythology gods after having defeated Zeus, and the other Greek gods. Whether this story is yet to unfold, remains to be seen.
By technicality, Kratos managed to free himself from his past in Chains of Olympus. When he gave up his weapons, powers, and abilities, Kratos' tattoo and pale skin were also removed, thus granting him amnesty. Unfortunately, he was forced to regain everything at the cost of his daughter, Calliope.
The main series saw Kratos being stabbed through the stomach, at least once, in every entry.
Most of Kratos' actions during the series were driven by rage and vengeance, except when searching for the Ambrosia to save his daughter, and when saving his brother Deimos, ignoring any and all godly warnings.
In the series, when Kratos encounters any of his brothers or half-brothers, he initially does not intend to battle them, but later on does when they either provoke him or challenge him. Examples are Perseus andHercules.
In early screenshots of God of War, Kratos' tattoo was in the shape of the omega symbol when it was seen on his head.
If both players choose the default costume, P2 will have everything Kratos has red turned blue.
Also, if both players choose his alternate costume, P2 will have Kratos' red tattoo in yellow.
Kratos Medusa's Gaze Fatality is pretty similar to the Medusa's Head Fatality, used by Pagan, a female witch that is from the fighting game called "War Gods", which was developed by Midway, the former company that made Mortal Kombat games.
In his ending, his golden fleece is missing.
His alternate costume is known as "Fear Kratos" from God of War 3.
In Test Your Luck, if Armless Kombat is selected when playing as Kratos, he will only be able to perform four attacks that actually damage the opponent: Front Kick, Back Kick, Spartan Knee and the jump kick.
Whenever it is time to finish Kratos, he will drop his Blades of Exile.
Also, when Kratos is going to finish the opponent, he will unsheathe his Blades of Exile, even if the finisher does not use them at all.
If Kratos is frozen after he drops the Blades of Exile, they will freeze along with him on the ground, no matter how far away they are from him.
Mortal Kombat (2011) is actually the second fighting game in which Kratos appeared in as a guest fighter. The first being Soul Calibur: Broken Destiny for the PSP.
Whenever a Fatality or X-Ray Move is performed on Kratos, his mouth will not move for some reason, or he has a different animation compared with others. Even when he screams during a Fatality, his mouth does not move. But when he wins, it moves just fine. He also has different reactions to some Fatalities, which, according to Ed Boon, were done to prevent Sony Computer Entertainment from sueing Netherealm Studios. Some examples are:
If Johnny Cage performs his And The Winner Is... Fatality on Kratos, he will not get a trophy planted in his head.
If Mileena's Be Mine Fatality is performed on Kratos, she will not eat Kratos's face, instead she will immediately drop it on the ground.
If Ermac's Pest Control Fatality is performed on Kratos, Kratos will yell at Ermac instead of running around in fear. This could be because he has fought Cronos, who, in body relations, is much larger.
When Raiden does his Transplant Fatality, Kratos' mouth is closed, but light can still be seen coming from his mouth.
When Smoke performs his Smoked Out Fatality on Kratos, his Blades of Exile fade away with him.
Also, when Smoke performs his Tremor Fatality on Kratos, his mouth will stay closed, but smoke will still come out of his mouth.
When Shang Tsung performs his Identity Theft Fatality on Kratos, the green glowing lights are placed higher than his eyes. This is probably due to the fact that Kratos' head is a lot smaller than the MK characters'.
