This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
獟 combines the animal radical 犭 with 堯, but the exact historical development and original meaning are uncertain. It may have originally referred to a type of animal or a descriptive term, but no clear etymology is available.
With no clear meaning, focus on the shape: a wild animal 犭 beside a tall, layered structure 堯. Imagine a fierce beast guarding a high tower.
For ゴウ, picture a strong, roaring beast: its growl sounds like 'gou' (ゴウ), echoing from the tower.
