Sethan

Sethan is the stand of Alessi featured in Part III: Stardust Crusaders.

Appearance
Sethan is bound to Alessis's shadow, taking its form but with a distinguished shape, the most prominent feature being its large eyes.

Ability
Age Reversal: Anyone standing in Alessi's shadow will age backwards at a rapid speed. Polnareff, who touched it for a split second, ended up as an approximately 7 or 8 year-old child, while a woman probably in her twenties stood in it for ten seconds and was reverted back into a helpless fetus. In the fighting game based on Part 3 it's revealed that the older the person is, more time and power is needed to reverse him to a child.
