Sharpner attends Orange Star High School with Gohan. He torments Son Gohan for a bit in school, but later befriends him after witnessing his athletic prowess. Sharpner likes Videl who also attends Orange High School. He is very athletic and likes to work out, yet it seems he does not do any martial arts practice. Early on Sharpner devotes most of his time to finding out who the Great Saiyaman is during the 25th Tenka-ichi Budoukai. He later discovers that Gohan is the Great Saiyaman and is disappointed that the answer was right under his nose. Like Erasa, his fate is unknown after the Buu saga. Also like Erasa, he was named after school supplies, with Sharpner's name coming from the word "sharpener."
