Gigan

"Monster of Steel" Gigan is a notorious criminal. He was imprisoned in the Underworld until being freed by Miranjo. He has sworn his loyalty to Bojji, becoming the prince's second retainer.

Appearance
Gigan is a massive monster with green skin, pale yellow eyes, and pointed teeth. He stands at least twice as tall as an average human, though he is still significantly smaller than a true giant. He wears a brown animal pelt held in place by light brown suspenders, a red helmet with devil horns, and wields an enormous two-handed hammer.

Personality
Gigan is a monster of few words, and while he is capable of horrific violence he does not seem to relish it like his fellow escapees. He seems to be moderately intelligent.

Gigan also appears to have some sense of personal honor, and submitted to Bojji's leadership after the prince beat him in battle.

Plot
Gigan is one of the Underworld prisoners freed by Miranjo to conquer the Bosse Kingdom.

An enormous threat on the battlefield, Gigan alone was able to wipe out half of Queen Hilling's personal guard. He repeatedly crushed Hilling's knights with his massive hammer, and managed to temporarily subdue the Heavenly King Drushi (though Drushi 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 instantly knocked out Gigan with an attack that was too fast to perceive. When Gigan regained consciousness later he attempted to attack Bojji again, only to be instantly knocked-out once more.

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).

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

 * It is unclear what crime Gigan committed to be imprisoned, but the Underworld does not allow monsters to migrate to the overworld, so his presence in the Bosse Kingdom alone is punishable by death.
