In the book series "The Secret of Nicholas Flamel" Marethyu is a time-traveling person going to different times as he pleases, his name also means "death" in the language of Danu Tallis, Marethyu also has no aura or aura scent as he uses the power of the hook

SPOILER:
Marethyu turns out to be Josh, and the hook (his power) is the four swords or power combined together with his left hand
Wow Marethyu really shocked me in the "Warlock"
