Kratos God Armor from GOW

"Athena! You conspire against me?" -Kratos to Athena in GOW2 Intro.

"Before there was a god...before there was a warrior, the Oracle had foretold of The Marked One. Every past has its ghosts. Every end must first begin."
— Gaia, E3 2010 Trailer

"Kratos, the Ghost of Sparta, had taken his place amongst the Olympians as the God of War. The bloodshed, the relentless battles had finally brought him here. Ares was dead. And though Olympus beckoned, visions of his mortal existence still haunted him."
[...]
"Kratos knew that this was not a mere vision. For with the gods, nothing was ever as it seemed. The vision of his past set Kratos in search of answers; Answers that lay in the temple of Poseidon, deep within the city of Atlantis."
— Gaia, opening narration

"You are no challenge for a God."
— Kratos in Soul Calibur Broken Destiny.

The God of War Armor appears as a costume in Ghost of Sparta, God of War II and Soulcalibur: Broken Destiny.

Ghost of Sparta
The original God of War Armor, as Kratos wore it in the beginning of God of War II.
One of the first bonus costumes decided upon including with the game was the God Armor. Developers have also revealed Kratos will wear the armor in-game at some point, before being able to unlock it. Another interesting bit of information about this armor is that Deimos' armor features some striking similarities.
This costume decreases the amount of damage Kratos receives from enemies, doubles the damage he deals with Blades of Athena, Thera's Bane and the Arms of Sparta and also double the fire meter regeneration time. Although the Combo Time increases by x2. Finally, it also causes enemies to drop Red Orbs as Kratos hits them with attacks. The God Armor is unlocked by beating the game on any difficulty.
If the player chooses God Armor when starting a new game, the player will notice the color of Blades of Athena turns to black and red, similar to when the blades are engulfed in Thera's Bane (glyphs remain blue in normal mode) and shine gold when reflected by light.
With the god armor, The Bonds of Ares and Aphrodite's Ambrosia; Kratos effectively becomes the semi-god of war (as he hasn't attained full godhood which is seen at the end of the game) as the bonds grant him infinite magic, the ambrosia grants him superior physical attack, 'The Might of Sparta', the armor reduces the damage taken from enemies at a great deal which keeps Kratos almost immortal. All of the privileges that suit a god of Olympus. Using the god armor, the bonds and the ambrosia allows the player to beat the game in a godly style.

God of War II
This is the outfit Kratos wore at the beginning of the game when he attacked Rhodes and fought the Colossus of Rhodes, only now to be worn indefinitely, granting the blue Blades of Athena as well, though the chains remain red oddly enough. After the Colossus injures Kratos, the armor is almost completely destroyed, save for Kratos' loincloth and footwear. The God Armor is described as "You worked so hard to get it the first time. It would be a shame to let it go to waste." After receiving a "God" ranking or higher in Challenge of the Titans, the armor is unlocked and the description changes to "Wear armor of the God of War to inspire fear in your enemies."
Wearing this costume doubles all of Kratos' stats, making it the most advantageous costume in the game even on titan (very hard) mode.

In Soulcalibur: Broken Destiny
The God of War armor serves as Kratos' secondary costume.

The armor looks very similar to the armor Kratos wore as the captain of the Spartan Army, and in God of War III for the "Dominus" costume.
The armour was also seen as an easter egg in PS3's Heavenly Sword.
This costume, along with Deimos', is one of the only two costumes that were made available in two God of War games.
The God Armor is seen in PlayStation All-Stars Battle Royale in Kratos' third super where he grows three times his normal size, acquires his godly armor, and uses the Blade of Olympus to strike his enemies down.
The chest piece of the armor is brown in Ghost of Sparta and God of War II but in the NECA action figure it was black.
There is a small difference between the God Armor in God of War: Ghost of Sparta and God of War II; in God of War II (as well as in Soulcalibur Broken Destiny) the gauntlets have chains wrapped around them, whereas in God of War: Ghost of Sparta, the gauntlets appear to be slightly smaller and have no chains.
Design traits from the armor, appear in the Ares armor set in God of War (2018) and God of War Ragnarök both in New Game Plus.

Kratos' role in the Soul series seems to be debated among fans. However, he is obviously non-canon, like the other guest characters.
Kratos's backstory and persona is somewhat similar to Siegfried: both of them accidentally killed their families, in the case of Kratos, he killed his wife Lysandra and daughter Calliope, while Siegfried killed his father Frederick, both of them seek atonement for their past sins. Strangely enough, both also have a scar over their right eye.
During Soulcalibur Broken Destiny's opening, Kratos is pit against Sophitia due to their Greek backgrounds and opposing viewpoints, with Sophitia serving the gods and Kratos (formerly servant) against them.
Kratos' profile for Broken Destiny is also similar to Keres' backstory. Both were summoned by a Fygul Cestemus member seeking revenge, and both killed the ones who summoned them.
The first part of Kratos' Critical Finish references a move from the final boss battle in the first God of War in which Kratos stabs a sword into Ares, leaps upward and pulls it out while slashing downward.
When he does his Critical Finish, he says afterwards "Behold the power of the gods!" However, if it is done on Sophitia, he will instead say "I am the God of War!"
This is the first fighting game to feature Kratos. He would later appear in the PS3 and PS Vita versions of Mortal Kombat (2011). He also appears as a playable character in the crossover platform fighting game PlayStation All-Stars Battle Royale alongside fellow guest fighter Heihachi.
Although they would not appear in the same game, Spawn—who appeared in Soulcalibur II—would later appear in Mortal Kombat 11 as a DLC character.
In several of Kratos' attacks, he uses magical items from the God of War games. Shown in gameplay were Poseidon's Rage, Atlas Quake, the Icarus Wings and the Blade of Olympus.
His alternate costume is his God of War Armor from God of War II.
Kratos' name is the same as the father of Lloyd Irving, another guest character from Soulcalibur Legends. However, their names are pronounced differently.
Sometimes, in Soulcalibur: Broken Destiny, at the start of a match, the announcer will say, "Fight like the God of War." He is most likely referring to Ares, the Greek god of war.
One of Kratos' pre-combat lines is "Your end begins!". This is a reference to one of the promotional taglines for God of War II, "The End Begins".
Kratos is the only character in whose soul lies an emotion present in another character's soul (Yoshimitsu, who also has Vengeance in his soul).
Kratos' weapons are called Blades of Chaos, though by the end of the first God of War, they were replaced with the similar Blades of Athena.
Despite being called Blades of Chaos, many of Kratos' weapons resembles the different forms of the Blades of Athena seen in God of War II.
Kratos' throws reference moves against specific enemy types in the God of War games.
Kratos is one of two characters from Greece to not use a sword and shield, the other being α Patroklos (although the latter's regular form does use a sword and shield).

Ah yes, I've been saving this guy. As you may have noticed, this Kratos has the God of War 3 and PSAsBR model. Honestly, I think he looks great, so I'm sharing him with you. Anyway, enjoy Kratos in his war armor. By the way, what were your favorite scenes of Kratos using this armor? Mine is the battle against the Colossus of Rhodes in God of War 2.
