Dolems or Dorems (ドーレム, Doremu?) are enormous mecha-like beings that are used as powerful weapons by the Mulians. The name "Dolem" is derived from "golem". It is also a reference to the first three notes in the C major scale, "Do-Re-Mi", and the Italian word "dolere", meaning "to ache".
In RahXephon Dolems are designated by TERRA as D1. The smaller fighters Dotem (with T instead of L) are designated as D2.
Dolems are made of clay, like golems, but are animated by a quasi-mystical force connected to music, as most of the controlling Mulians appear to be singing. A Dolem attacks while singing, and sometimes the attack is the song itself. Each D1 Dolem is bound to a Mulian who controls it. Some Dolems are also bound to human hosts called "sub-Mulians" or "Dolem hosts" who anchor to the Dolems in the human dimension, making it possible for the Mulian controller to take over the body of the host. These bonds are so strong that destroying a Dolem can kill both the Mulian controlling it and the human host. When destroyed, a Dolem disintegrates into blue blood and clay.
