Synopsis: Goku begins acting strangely, and admits to Gohan and Goten that he thinks someone wants to kill him. Meanwhile, in Universe Six, Hit carries out an assassination mission by killing a crime boss. His next target is revealed to be Goku. Goku senses Hit coming and flies to a remote area so that their fight would not put anyone else in danger. Hit arrives to kill Goku. Goku charges at Hit but cannot hit him. Hit seemingly kills Goku with a single blow to the chest, and then disappears just before Piccolo, Gohan and Goten arrive and find Goku's body.
