Tayzh

Tayzh is a core character who learns the Jitterfist technique from Ross Pfeiffer during the time skip between Book I and Book II. Initially struggling to get the hang of it, Tayzh eventually surpasses Ross's own mastery of the ability. After finding that Forrester committed suicide, Tayzh and Mantso pursue Siv, using the information they gathered while saving a group of children and mothers. During this pursuit, Tayzh unlocks a new level of Jitterfist, applying the high-frequency vibration to his legs to achieve incredible speed and leaping power. By Book III, Tayzh makes the critical decision to leave Ail and live on Earth. He joins the police department, leveraging intel from Snap's book of secrets, and masters Jitterfist for his entire body. Ross's dying words — asking Tayzh to get the baby — lead him to care for Phoebe, raising her on Earth. At the climax, when Orion drops gravity onto Haley and Clone Sunny in the observation cavern, Tayzh is the only one fast enough and clever enough to slip out from under it. He breaks for the fight — Phoebe is a child squaring off against a god-level opponent in Mantso, and Tayzh refuses to leave her there alone.
