In the Inspector panel, the Follow body position property determines whether the character will follow your body transform. Deselect this property if you do not want the character to match your body movements. You can then customize the character’s transform properties.

Remember to deselect Auto Sorting and manually set Sorting Order to ensure that the sorting order of the helmet is bigger than the alien entity. This way, the helmet will cover the alien’s head.
