Rainbow Scalpel/MeSH

This is a dark brown stallion with a white mane, red eyes, and glasses. His cutie mark is a scalpel dripping with rainbow liquid. He is an engineer at the Rainbow Factory as well as a medical doctor and insane biologist. He almost always wears a lab coat and a gigantic, crazy smile. His job requires he have no close friends or relatives, but he is the good friend of Binary Six and Henry Lockmare.

Rainbow Scalpel/MeSH's eyes used to be green but turned red after years in the Rainbow Factory.

Rainbow Scalpel/MeSH does not actually need glasses and simply wears them to scare failures.
