The head has a tentacle sticking out of its head that can be used as a whip and a human face is on the chest, giving it an appearance similar to the later introduced Warrior Beasts. In its inactive state, the Rhine X1's chest face is colored blue but after Lorelai Heinrich integrates with it, the face gains a flesh colored face and brown hair.
