Star Platinum

Star Platinum (スタープラチナ) is the Stand power of Jotaro Kujo and makes an appearance in nearly every JoJo part its user is featured in, most prominently in Part III: Stardust Crusaders. Its name is based on The Star tarot card of the Great Arcana. 

Appearance and Personality
Star Platinum is one of the first stands seen in the story and remains to be one of the most powerful. It appears vaguely resembling an Aztec warrior (a reference to the Stone Mask's origins), with black hair and blueish skin. Physically, Star Platinum shares some resemblance to Jotaro Kujo, having a similarly-sized body and even sharing some of his facial features especially when it was introduced. Like most Stands, it appears to be completely silent and mostly devoid of personality - though Jotaro has stated that it is very violent - unless it is punching, where it yells out "ORAORAORAORAORAORA" repeatedly, though it does possess, like most Stands, the basic ability of self-preservation, protecting Jotaro from Dio's Time Stop attacks when Jotaro was incapacitated.

Powers
Fitting as the Stand of the main character of Part III, Star Platinum is one of the most versatile and powerful Stands in the JoJo Universe.

Super Strength: Star Platinum is immensely powerful, able to throw a fully loaded Jeep carrying four full grown men and a small girl out of the path of an 18-wheeler with only one hand, then later pulling the same jeep out of a canyon with only a car as a counter-weight.

Super Speed: Star Platinum is said to have the speed and precision of a machine, capable of punching several times in a second, pummeling his opponent mercilessly. During his fight with the Stand Justice, Star Platinum protects Jotaro from many zombies surrounding him at the same time.

Precision: Star Platinum is amazingly precise, able to remove small objects from people's skulls without damaging the person's brain in any way, as well as catch bullets in mid-air.

Finger Extension: Star Platinum is capable of lengthening his index and middle fingers to stab an opponent from a distance. This ability seems to be easy to do, as it functions as a surprise attack. This ability is called "Star Finger" in the arcade game.

Time Freeze: Star Platinum is capable of stopping time, similar to its owner's grandfather's Stand, The World, albeit only for roughly three seconds. This ability seems to be extremely exhausting, as Jotaro only uses it once in Part III, and it was only discovered during the fight with The World.

Star Platinum: The World
There is no noticeable difference in the capabilities of Star Platinum: The World (スタープラチナ・ザ・ワールド) in comparison to the original Star Platinum, other than Jotaro has seemingly mastered the Time Stop. Time stop can now last for 5 seconds, and can be done consecutively with only a few seconds between each interval.
