The World

The World (世界 (ザ・ワールド) Za wārudo) is a stand featured primarily in Part III: Stardust Crusaders.

Personality/Appearance
The World resembles Dio in several ways, having a tall muscular body and the same green heart motifs it's feet look exactly like Dio's shoes. It has watch motifs on the back of each hand, symbolizing its power to stop time.

The World has never shown any personality, but in Stone Ocean, it was hinted that if not for Dio's own personality, it would go out of control.

Ability
The World is similar to Jotaro's Star Platinum with its phenomenal strength, senses and stamina, but is faster and more accurate.

Time Stop: The World's defining power is its ability to stop time, allowing only itself and Dio to act within the duration of stopped time. Given Dio's weakened state during Part III, however, this ability only works for a few seconds before time flows again.

Steel Ball Run
In the final chapters of Part VII: Steel Ball Run, another Diego Brando appeared, summoning a version of The World as his own Stand. This version has D-shaped emblems instead of hearts. The alternate Diego uses The World in much the same way as the original Dio did. It is unknown if this version of The World has the same statistics as the original.



Of note is the fact that the main Diego Brando of the Steel Ball Run universe does not possess/use The World, but rather Scary Monster.

Trivia

 * The World has evolved into an internet meme "Za Warudo". This comes from when Dio would stop time in the games and anime. He shouts "The World!", but because of the lack of a "th" sound in Japanese and "n" being the only sound without a following vowel, the pronunciation became "za warudo".
 * It has a great physical resemblance to Josuke's stand Crazy Diamond, and they both share an ability relating to time manipulation.
 * In the manga The World doesn't speak or make any noises besides its battlecry of "Muda", but in the OVA it makes silent roaring noises whenever it's attacking (and it let out a loud one when defeated by Jotaro) but strangely enough only Dio uses the battlecry of "Muda" during the OVA, while The World largely remained silent besides its aforementioned noises.
 * The World as seen in Steel Ball Run is actually not the same design as the one featured in Part 3, but the redesign of it seen in the JoJo A-Go!Go! artbook. The only notable difference are the kneepads that are shaped like the letter "D" instead of hearts.
