Xerxes

Xerxes was the 4th Savior, and the second to be encountered during Nightingale's 13 Days.

Personality
Xerxes appears as an overally proud person, and quite arrogant while boasting his strength. He shows no fear of sympathy during his fight with Nightingale, and was driven with his ambition of killing her.

13 Days
Xerxes' rift was found inside a sand-filled preschool, which then lead to the endless desert where Nightingale found herself stranded in for quite some time. Within the desert, Nightingale stumbled across the remains of a crashed and long-deserted airplane, which had become Xerxes temporary residence within the rift. Inside were the skeletons of the passengers aboard, and a collection the severed hands, presumably childrens due to the described size. Not long after exiting the airplane, Nightingale encountered Xerxes personally and quickly iniated battle between them. Even with his ability to transform into sand, he was slowed down with water, which turned into mud before he was struck down with a lightning bolt turning him into glass. His solid glass remains were then smashed and his soul was taken.

Trivia

 * Xerxes' ability to turn into sand and reform is similar to Sandman's power in Marvel Comics.
