Sun appears as a replica of the actual sun, though believed to be much smaller. It has no personality outside of serving its user as an almost-immobile entity. It represents the Tarot Card The Sun.
- Sun Replica: Sun is able to increase the heat of the surrounding area exponentially, as well as provide a large amount of light. A desert at 8:10 P.M. was recorded at a temperature of 80 degrees Celsius (176 Fahrenheit) from its power, hot enough that a scorpion caught fire and burned to death when it stepped onto a rock, as well as being bright enough that it was thought to be much earlier. It seems likely that Arabia was affected by his own Stand's power due to the use of the air conditioner in his vehicle and his inability to attack the party on his own.
- Lasers: When Sun is threatened, it is able to shoot lasers with alarming precision out at its target in a shotgun-like dispersion, able to shatter a pair of binoculars in Joseph Joestar's hands while he hid under a rock (the Stand's precision is ranked at E, however). These lasers seem to be more powerful than Noriaki Kakyoin's Emerald Splash, as he was forced to abandon the attack when faced with the barrage of the lasers.
- Araki admitted that despite the creative designs of the other tarot-based Stands, with a name like "Sun", its appearance only seemed appropriate.
