Gigan

Monster of Steel, Gigan (鋼の怪物ギガン, Hagane no kaibutsu gigan) is a side of the manga and anime adaption, Ousama Ranking. Is a former warrior of the forces of the Underworld who, after betraying the army of the king of Desha, was imprisoned in the dungeons of the Underworld. Until, he was released by Miranjo to invade the Bosse Kingdom along with other criminals from the Underworld.

After being defeated in combat by Bojji, Gigan pledged his loyalty to the prince and currently, forcibly recruited into the Order of the Underworld, absolving him of his past crime.

Appearance
Gigan is a gigantes with a huge size that is at least twice that of the average human, he has an incredibly corpulent physical build and bright green skin. He has facial features similar to an ape, has round eyes, without irises and with pale yellow sclera, in addition to large dark circles and pointed teeth.

Gigan wears an outfit consisting of a dark brown animal skin tunic and skirt, under a large tan battle harness with iron buckles. A red helmet with small pointed horns and white bandages on his forearms, in addition to gray leather semi-short pants and black leather shoes.

Personality
A monster of few words and a hardened warrior, Gigan doesn't shy away from fighting, but has a personal sense of honor that sets him apart from the other Underworld prisoners. He seems to be moderately intelligent.

Plot
Years ago, Gigan was hired as a mercenary for then-Prince Desha's army, fighting to unseat Desha's father. Unfortunately, the rest of the gigantes race allied with the old king, setting Gigan in opposition to his own people.

Desha's army committed war crimes in order to combat the gigantes, including torturing gigantes children in order to bait gigantes soldiers. After personally witnessing the depravity of his own squad, Gigan rebelled and wiped out the squadron of soldiers with his bare hands, causing heavy losses before being subdued.

In spite of their losses, Desha's army won, and a victorious Desha sentenced Gigan to imprisonment in the Underworld dungeons, where he remained until being freed by Miranjo to conquer the Bosse Kingdom.

Initially allied with Miranjo and the Underworld prisoners, Gigan proved to be an enormous threat on the battlefield. He alone was able to wipe out half of Queen Hilling's personal guard, and managed to temporarily subdue a master combatant like Dorshe (though Dorshe was already exhausted at the time). Gigan was even able to defeat the giant snake Mitsumata with only his monstrous strength.

The tables turned for Gigan when Bojji entered the battle. Using his new form of swordsmanship, Bojji easily subdued Gigan. After being beaten twice in short order, Gigan bowed his head to Bojji and formally acknowledged Bojji's strength, becoming the young prince's second retainer (the first being Kage).

After a brief altercation with the Order of the Underworld, King Desha, Domas, Hokuro, and Bojji, Gigan was formally inducted into the order, as he represented the values the order's founder wished for all knights to have. Desha then took his leave, returning to the Underworld with his knights, including Gigan.

Inhuman Strength
Gigan is many times stronger than the average human, able to wield a massive hammer and crush multiple opponents in one swing.

Trivia
