Son Goku's descendant

is the descendant of, the "Monkey God-King", "Great Sage, Equal of Heaven", and "Buddha of Victorious Strife".

History
Together with Sha Gojyo's descendant, Son Goku Jr. is one of two enslaved-servants of Chokyūkai (descendant of /)), helping him to abduct beautiful young maidens by using tiara-like golden bands (like the one used on Son Goku Sr. to control him with the "Headache Sutra" (similar to Inuyasha's Beads of Subjugation)) to control them (and the same ones used on them). They began after being freed from a shrine that was destroyed by a hoard of yōkai following the collapse of Mount Hakurei.

Inuyasha and his friends confronted Chokyūkai and his servants after Kisuke asked them save the women of his village from Chokyūkai. Despite the legend that held the achievements of his ancestor, Son Goku prove to be really weak as he was easily scared when Inuyasha simply glared/snarled at him. He left with Chokyūkai on a twister after his master possessed Kagome to become his newest bride.

He returned later with Chokyūkai when Hakudōshi was collecting the heads of other yōkai. Chokyūkai tracked down Hakudōshi and Kagura, watching as Hakudōshi attempted to peer into the yōkai heads to catch a glimpse of the Border of the Afterlife. Son Goku and Sha Gojyos' descendants silently accused him of being cowardly when he hid in the grass, but Chokyūkai retorted that he's just not heartless enough to fight a kid like Hakudōshi.

Their conversation was interrupted when Entei approached him from behind, unbeknownst to Chokyūkai. Son Goku and Sha Gojyo's descendant fled at the sight of the horse yōkai and Entei knocked Chokyūkai backwards. Enraged that a mere horse would attack him, the boar attacked, but Entei merely kicked him into the distance, leaving the other two descendants to chase after him.
