Zack Rosales

Zackary Diego Alfonso Rosales, like many other characters in the Infinite Series Universe, most notably Ayden Jaubertand Marie-Anne Davis, was what is known to be a John Titor— a "military" time traveler originating from another dimension.

He was the older cousin of Lena Rosales and best friends of Ashlyn Cordell and, for a short time, was one of the main antagonists in the Within The Force Series, before finally perishing. He is the first character in the entire Infinite Series Universe to have only been "reborn" once.
