When Goku goes seeking the Ultra Divine Water, Darkness watches him fight an Ice Monster along with Yajirobe. As they try to escape it, they fall lower into the chasm. Yajirobe runs higher again, while Goku descends deeper into the cave. He soon finds Darkness in the form of Master Roshi, who takes Goku to what appears to be Kame House. In the form of Bulma, Launch, Oolong, Puar, and Yamcha, he tries to convince Goku to remain with him forever.
Not realizing the deception, Goku calls them all cowards and attempts to leave. "Master Roshi" tells him that he cannot get the water and says he will have to kill Goku. They fight, but are interrupted by Yajirobe falling from above. Yajirobe and Goku fall into a chasm, with Goku barely saving them. Darkness tells Goku to just let go, but Goku refuses, even when Darkness starts beating him. Eventually, Darkness knocks them down, but saves them. He decides that Goku is worthy of drinking of the Ultra Divine Water, but warns Goku of its power. When Goku succeeds in drinking the water, Darkness sinks into the lake, never to be seen again.
Darkness has the power to take on the likeness of anyone, but chooses people close to his next victim, presumably by using some form of telepathy. When he fights Goku in the form of Master Roshi, he displays telekinetic abilities, being able to levitate objects and throw them without touching them. He also displays the ability to send an electrical current through a person's body, thus shocking them. He seems to be able to use the Magic Materialization technique, since he is able to make a replica of Kame House. There is also the possibility that all those abilities are just illusions, and Darkness merely toys with people's minds, killing them using his mental powers. Darkness seems to be immortal, as remarked that he and Goku could live together for all eternity.
