Deathgaze, Leinad's Kyurem
Kyurem was a Pokémon that became legend in Lacunosa Town as a monstrous Pokémon that would kidnap humans out at night. This wasn't proven until Natalie was kidnapped by the beast. This Kyurem was later caught by Leinad when he went to rescue his friend. Because the humans Kyurem captured were never seen again, with the sole exception of Natalie, many began to call it the 'Shadow of Death'.
