Due to Dammek's influence and the general mistreatment of low-bloods in Alternia, Xefros does not think highly of himself or any of his abilities, and shows some anxiety over his fading childhood. Xefros is a timid, passive troll with a kind heart and low self-esteem. Joey manages to save Xefros and the two leave with both Dammek's and Xefros' lusii to meet up with Xefros' friend. He tries to help her, despite the dangerous Drone raid going on in his neighborhood, but a missile hits his home and he gets trapped under the debris, forcing Joey to save him instead. He initially believes Joey is Dammek testing him before realizing she is a lost alien who has somehow been sent to Alternia. Xefros is first seen shortly after Joey Claire is spirited away to Alternia and Dammek is similarly sent to Earth. Tritoh also sounds similar to the Germanic word "Trikot", meaning a sports jersey.

His surname refers to his Sloth lusus, resembling "tri toe" to reference the Three-Toed Sloth. Xefros is possibly named after Zephyrus, the Greek god of the west wind. You can also translate the word "Xefros" (yes, there is a difference between "xefros" and "Xefros" in the Greek language) into the Greek word "Ξεφρος" meaning "dazzling". The word "xefros" comes from the Greek word "ξεφρος", meaning "mad", possibly referring to his Rage-bound sign.
