A 3 inch tall neera boy hailing once from lands hidden deep within previously untouched forest who accidentally got caught up with an exotically dressed human explorer after stowing himself away in her backpack. Accidentally trapped within, he was taken from the only place he knew as home. After forming a bond with the girl, he took a greater interest in human civilization.

Zach sports messy dark hair, tall ears, and a long tail like that of a common mouse measuring at roughly 5cm long on his 8cm self. Aside from abnormal humanoid features he wears a favored outfit consisting of clothes sewn specifically for him by his human caretaker when asked to make more "human-like" clothing. The outfit consists of a white shirt, a green pocketless hoodie, and dark blue pants sewn to look like jeans all made from similar material and seamlessly flexible for it's size.

Fitting well with his rather large ears is his keen yet sensitive sense of hearing, making subtle quiet sounds easy to pick up on while sudden loud noises range from startling to outright painful to hear. Following his more noticeable mouse-like features are his less visibly noticeable heightened sense of smell and taste, making him particularly drawn to human cuisine, a notable favorite thing of his since his major change in lifestyle. A more recently learned talent of his is his excellent ability to climb, as getting around in a world made for people 22 times your size can be difficult without it. Zach excels at climbing fabric quickly and efficiently as long as there is a place to grip, while harder surfaces can prove to be more of a hassle. Following other features shared with mice is his ability to squeak like one. Often times when startled or squeezed, Zach will let out a squeak near indistinguishable from an actual mouse. While mostly heard involuntarily, he is fully capable of squeaking on demand but tends not to as he finds it embarrassing.

Zach can be rather eager getting to know new people both big and small, dedicating a large portion of his new life to curiosity and learning how things work which can be both to his benefit and detriment alike. Gullible as he can be at times, he's no idiot. Zach is a fast learner and often applies his knowledge of his old life to the surprisingly similar human way of living.
