Zack

Zack is a human teenager and the host of Hades.

Character History
Zack's childhood is unknown, but he reached senior high school, and apparently befriended Isaac, Nathalie's older brother. He dared Isaac to dump Nathalie's lunch tray all over herself, and when he balked, did it himself. As he enjoyed the results of his prank, Jet confronted him, demanding he apologize to Nathalie. When he refused, Jet bloodied his nose.

Shortly thereafter, Zack found all of the Rangers, and asked to talk to Jet. He apologized, and when an incredulous Jet asked if he meant it, he laughed and said of course not. Angry, Jet tried to punch him again, but Zack ducked and Jet put his hand through a window, exactly as Zack had intended. All of the girls were furious, though that didn't bother Zack nearly as much as the black eye Lew gave him.

As Zack sulked, plotting his revenge on Lew, he was struck by a sudden pain to the head, and his eyes flashed red. Suddenly much calmer, he left. Soon after, he was declared a missing person, and the Rangers deduced that he'd been possessed by Hades.

Personality
Zack is a prankster, and a vengeful one at that, with a tendency to mock or harm anyone who annoys him.

Talents and Abilities
Before becoming Hades' host, Zack was mildly clever, though not nearly as tough as his jock reputation might imply.

Appearance
As a senior in high school, Zack is presumably 17-19 years old. He's described as a jock.
