The Shandera family have some pretty creepy Pokedex entries:
Hitomoshi
"It lights its glow and, while pretending to guide their way, sucks out people's life force."
Ranpuraa
"It appears when one is on the very brink of death and absorbs the soul the instant it has departed from the body."
Shandera
"Anyone enveloped by the flame of a Shandera will have their soul sucked out and burned. Only an empty shell of a body remains."
