THE BERSERK FORMSaix transforms into his Berserk form in the final battle of Kingdom Hearts II. The following information is based on his transformation in Kingdom Hearts II
Although Saix is a calm and collected character, as soon as he starts to battle you, he becomes angry, wild, and very dangerous. The true danger comes out when he is in his Berserk form. He uses the power of the moon here to enhance his powers. Not only does his Claymore change, but Saix himself becomes more like a beast. His eyes glow yellow, his hair goes all over, and he grows fangs. His strength and speed increases significantly as well. The scar on his face gets bigger and his body transforms into a beast. It is very frightening and a challenging battle, but doable. For more information on how to defeat Saix in this form, check out the next page for defeating Saix in battle.
In mythology Berserkers, or Berserks, were Germanic warriors who were primarily reported in the Old Norse Literature to fight in an almost uncontrollable trance-like state of mind. Most historians believe that Berserkers worked themselves into a rage before battle, but some think that they might have consumed drugged foods. They were said to wear a belt of a wolf when they went into battle as well. To "go berserk" was to "hamask" which translates as "change form," in this case, a with the sense "enter a state of wild fury" and one who could transform as a berserker was typically thought of as "hamrammr" or "shapestrong."
"I'll ask of the berserks, you tasters of blood,
Those intrepid heroes, how are they treated,
Those who wade out into battle?
Wolf-skinned they are called. In battle
They bear bloody shields.
Red with blood are their spears when they come to fight.
They form a closed group.
The prince in his wisdom puts trust in such men
Who hack through enemy shields." - a skaldic poem composed by Thorbiorn Hornklofi in the late 9th century in honor of King Harald Fairhair
Scholar Hilda Ellis-Davidson created a theory called "berserkergang," meaning "going berserk," saying that it not only occurred during battle but from doing work as well. This condition is said to have begun with shivering, chattering of the teeth, and chill in the body, and then the face swelled and changed its color. With this was connected a great hotheadedness, which at last gave over into a great rage, under which they howled as wild animals, bit the edge of their shields, and cut down everything they met without discriminating between friend or foe. When this condition ceased, a great dulling of the mind and feebleness followed, which could last for one or several days.
