Eternal Turtle School of Martial Arts
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Eternal Turtle School of Martial Arts presumably continued the teachings of Turtle Hermit's former master, Mutaito. The first two known members of the Eternal Turtle School were Grandpa Son Gohan and Gyumao. The special moves which were taught to the students were the Kamehameha and Jan-ken. They also had a rivalry with the Crane School founded by Crane Hermit and Tao Pai Pai.
Turtle Hermit had officially retired in Dragon Ball Online, though (the now presumably deceased) Kuririn had founded the New Turtle School after he had read Son Gohan's book "Groundbreaking Science". In-game, the Spiritualist class belonged to the Human race and excelled in the use of spiritual energy rather than physical techniques. Spiritualists could obtain the status of Turtle Hermit through the New Turtle School or Crane Hermit through Tenshinhan's New Crane School. Kuririn had decided that the New Turtle School should put emphasis on teamwork. In the anime, Roshi had Goku and Kuririn work against one another.
Canon techniques of the Turtle Hermit master class are Kuririn's Scattering Bullet and Goku's Super Kamehameha, while all Spiritualists learn the Destructo Disk, Kamehameha, and even Yamucha's Spirit Ball. Dragon Ball Online's Martial Artist class builds warriors similar to both Goku and Yamucha from the early arcs of Dragon Ball, who were at the time students of Roshi. Martial Artist techniques are the Jan-ken and Rogafufu-ken (though this is not a technique of the Turtle School, only being used by the practioner Yamucha). They also obtain the Concentrated Kamehameha technique.
The graduates of Turtle Hermit's training often included the kanji for "Turtle" ("Kame") 亀 on their gi. Characters related to Goku always seemed to wear the Turtle School colors of orange and blue in homage to Goku, yet did not wear the insignia. This is possibly a sign of respect for him or that the creator Akira Toriyama wished for the viewers to the visual likeness between him and his sons. First, his son, Son Gohan, was given a replica of Goku's gi in the early and later arcs of Dragon Ball Z, except that Gohan wore Piccolo's "demon" kanji rather than the Turtle School insignia during the Saiyan Saga. Had his father not abandoned the Turtle School's insignia, Gohan too would have worn it in his battle against Boo. Future Son Gohan also wore his father's colors (but with a replaced kanji) after his death, though it is worth noting that Future Gohan did not attend nor graduate from the Turtle School.
Goku's second son, Son Goten, also did not sport the Turtle School insignia despite wearing the Turtle School colors. In adulthood (the last episodes of Dragon Ball Z), he abandoned the blue undershirt and kept a similar kanji-less gi (in a similar fashion worn by Goku in his battle against Raditz). Neither of his sons were students of Turtle Hermit despite knowing the Kamehameha. This could be due to Goku and the other Z Warriors surpassing Turtle Hermit and taking it upon themselves to train the younger generation of warriors.
By the end of Dragon Ball Z, Goku had abandoned the orange and blue colors completely, however, Goku's granddaughter, Son Pan, wore an orange gi during the same period. In Neko Majin Z, Goku's disciple always wore his colors in the same fashion, yet wore a different symbol, "ne".
In Dragon Ball Online, the central cast of Dragon Ball Z had become famous through Gohan's book Groundbreaking Science. In 1000 Age, Humans still wore the Turtle School gi/colors (though it sometimes was personalized with black and orange, rather than blue and orange), but it is generally associated with the offensive melee class (Martial Artist) rather than Spiritualists, who become Turtle Hermits.
