|Game(s)||Episode 11: Pixie's Defeat|
Rocko is one of Pixie's slaves in the disc mines on Ancra Island. He is a large man with shoulder-length hair, and sad eyes. When Genki and Mocchi break into the prison and begin to set everyone free, at first the slaves are reluctant to try to escape because of the risk of injury, but Rocko sides with Genki, realizing this may be their only chance.
Rocko explains to Genki how their ancestors enslaved the monsters in the area for years, and how they would like to change the cycle. Later, he helps dig Big Blue, Genki and Pixie out of the rubble of the collapsed temple.
