form, appearance, countenance
貌 centers on the outward visible shape of something: its form, appearance, or the expression on a face (countenance).
貌 combines 豸 (a beast-like creature) with 皃 (appearance, face). The original idea may have been the outward look of a beast, extended to form or countenance in general.
A beast 豸 shows its form through its face 皃. Together, 貌 is the outward appearance or countenance of something.
For ボウ, picture a bow (ボウ) tied around a beast's face to change its appearance: bow -> ボウ, and the beast's form is altered.
