Jack vs. Demongo, the Soul Collector
Aku sends his servant Demongo, a demon who captures and enslaves the souls of fallen warriors to serve him, to destroy Jack. Realizing he cannot destroy the warriors’ essences, which keep reentering Demongo and respawning, Jack grabs a hold of a disembodied essence and enters a spiritual prison inside Demongo, where he frees the warriors’ souls, allowing them to overpower the demon. Back in his lair, Aku crushes Demongo in his fist for failing the mission.
