Arty is TMV's little brother. For most of their lives they were separated, until meeting again shortly after Arty met Klak. He was saved from destruction, unlike the rest of his family (except for TMV, Artroe, TTT, and John Freeman) and was trained by Telemecus.
Arty is about four foot tall and looks about nine years old. He has big blue eyes and short spiky fire red hair. His smile is warm and inviting. He is quite skinny and carries a large sword on his back. He wears a blue t-shirt and ragged blue jeans, and his right arm is made of energized protodermis.
