As a Stand User, Jotaro benefits from an immensely resilient constitution and willpower. While they are perfectly mortal and most certainly can be killed, Stand Users are infamous for being able to endure serious injuries and not just avoid being disabled by pain like the average person would but also keep fighting to the last, even after sustaining an inevitably lethal blow. Their souls are immensely resilient, to the point of being able to force a dying body to keep moving for a while or even linger long enough to convey a final message to others as they pass to the afterlife.
Jotaro's most notable ability is to summon a spiritual projection of his soul and fighting spirit called [Star Platinum], his unique Stand, named aptly so for the fact that it "stands beside you". All Stands possess a number of universal traits that vary in viability depending on the Stand's Precision, among which are:
Selective Tangibility
Size Changing (specifically shrinking)
Sharing Senses with their User
Self-Enhancement
Flight
General immunity to anything that isn't another Stand or spiritual attack.
Generally undetectable to any non-Stand User.
Damage Mirroring (any damage the Stand takes is mirrored onto the user).
In terms of unique strengths, [Star Platinum] is an extremely physically imposing Stand, possessing immensely inhuman strength, speed and precision, along with high durability. It is also able to briefly extend the length of its fingers a short distance, springing out like a spear. However, all these strengths are counterbalanced by the fact that it can only exert them within 2 meters of its user, being a prime example of a Close-Range Combat Stand. Beyond that range, the Stand rapidly weakens in effectiveness, soon reduced to little more than a ghostly errand boy.
[Star Platinum]'s most esoteric power is the ability to Stop Time (and conversely resist opposing time manipulation) for increasing increments. However, due to both a limited human body and disuse, the ability had a tendency to badly degrade over time. In his prime, Jotaro was able to stop time for 5 seconds, but he never truly pushed his limits for more. In theory, despite being human, he could have stopped time for much longer, perhaps generously 10 seconds, but the ability is physically straining, thus leaving humans with little capacity to do more. At the point this power was drawn from, however, the Time Stop was degraded badly to .5 seconds. This compounded by Mia's own inexperience means she will need to work hard to achieve the heights even Jotaro's prime was capable of, never mind surpass them.
- Vampire Enhancement: After becoming a Twilight-brand vampire, Mia's human vitality no longer remains a weakness. Though her speed of progression in improving her time control has not changed much, her maximum potential time stop is effectively infinite. Given time, she will, in theory, be able to stop time as long as she wants.
- Current Time Stop Duration: .8 seconds.
