Justice isn't "The ultimate stand". Every character in Jojo seems to think that their stand is the ultimate stand. The ultimate stand is obviously Gold Experience Requiem.
Ah yes, Qtaro strikes again and shows that the power of ๐บ๐๐๐๐๐๐ shouldn't be underestimated
Don't know how to solve a problem? ๐บ๐๐๐๐๐๐ will solve it for you
And yes, I have to agree
Gold Experience Requiem is the most powerful stand, but at that time it didn't exist
I like how at first Jotaro was so wary of his stand he locked himself in a prison cell, but once he learnt it's not an evil spirit, he just uses Star Platinum for literally everything.
Need to remove a parasite with surgical accuracy? The stand can do it.
Need to zoom in a small speck in a photo? The stand can do it.
Need to get rid of the deadly fog? The stand can do it.
Need to restart someone's heartbeat? The stand can do it.
In conclusion: Star Platinum's special ability is literally everything.
