Stand Cry

A number of Stands and/or their users make a repetitive cry while executing their basic mode of offense; informally described as a Stand Cry.

The cry is suggested or depicted as being made in a similar rhythm and intensity with the attack of the Stand, which is usually very rapid, strong, and unbroken.

The Stand Cry is among the trademarks of JoJo's Bizarre Adventure, as many central Stand users have one.

Origin
It is presumed that the Stand Cry originated from Fist of the North Star; in which protagonist Kenshiro (in a style after film star Bruce Lee) typically throws very rapid punches while crying "ATATATATATATAT ... !".

The most popular and common cry, "ORA ... !", originates with Japanese onomatopoeia (equivalent to the English interjection "hey!"); whilst "MUDA ... !" represents a Japanese word ("useless"). Others come from English and Italian.

Earlier in the series, in a style common to action-oriented manga, certain characters would scream the names of their attacks (including Jonathan, Joseph and Dio); so it is possible that the Stand Cry follows from this.

Trivia

 * "Ora" is also used by many non-Stand users, such as Jonathan Joestar, Joseph Joestar, Gyro Zeppeli and JoJolion Kira, interpreted as a sort of grunting sound.
 * Additionally, Giorno and Jolyne's cries are identical to their fathers, DIO and Jotaro; Giorno also shares his father's "Wryyy" screech. All this could possibly imply that the instinct to use these specific battle cries is hereditary.
 * Tusk's and Soft & Wet's battle cries are also references to Star Platinum's.
 * Excluding Polnareff and Bruno Bucciarati, who were introduced as antagonists before becoming allies, DIO, Kira and Alternate Universe Diego are the only antagonists to have a Stand Cry.
 * Sheila E is the first novel-only character with a Stand Cry.
 * Polnareff's cry can be translated to "Hey!" or "Come on!"
 * The cries belonging to Bucciarati and Narancia are derived from Italian words.
 * Bucciarati's means "Goodbye!" and "Farewell!"
 * Narancia's cry translates as "Fly away!"
 * Trish Una's cry derives from the Spice Girls' single "Wannabe."
