User blog comment:Sleeperagent3056/What if Kars ever returned to Earth?/@comment-121.208.90.157-20141119184136

1. Although they couldn't kill him, Stand users would mess him up.

2. No.

3. Dio didn't "discard" his powers of body manipulation; over the course of around ninety years (1889 - 1989), he simply forgot how to use some, like Space Ripper Stingy Eyes, the freezing, and hypnosis. While Kars' body manipulation is not as diverse and dangerous as Dio's, he has had more time to train and would likely still know how to generate and use the Light Blades.

4. Kars cannot see nor defend himself from Stands. He would be incapacitated.
