When he was at the World Tournament he saw that Gohan has amazing powers and is Great Saiyaman as well as the "Gold Fighter". Before the Tournament it is shown that he is in love With Videl when he gives Videl some flowers and tries to explain his feelings, but stops when he sees the Great Saiyaman (Gohan in disguise). Videl then walks away with Saiyaman. After this, Sharpner tries to unmask Saiyaman, as he believes it will impress Videl.
None of his attempts to unmask Saiyaman proved successful, however. He tried to dive on him and take the scarf off his head, but missed because Saiyaman was bending down to pick up Captain Ginyu the frog. Then, he got a kid to spray him in the face with a squirt gun, causing him to take his sunglasses off. Sharpner almost got a picture of him with his camera, but a man who wanted to compete in the tournament stood up, blocking Gohan from view. Then, Sharpner got another kid to get Saiyaman to lift him up so he could see, and he took Saiyaman's sunglasses off. Sharpner got a picture this time (though he couldn't see Gohan's face himself because the shutter was moving). Unfortunately for him, Piccolo destroyed all the cameras, including Sharpner's. He did not discover Saiyaman's true identity until his fight with Kibito.
He was killed when Super Buu annihilated all the humans on earth, though he was later restored to life with the Dragonballs. He was seen giving up energy for Goku's Spirit Bomb, along with Erasa and the others at the school, all cheering for Hercule, whom they thought they were giving their energy to.
