knock someone off their perch

Unseat the leader

To knock someone off their perch is to unseat them from a position of superiority or dominance.

The image is of a bird dislodged from its roosting spot.

It implies bringing down someone who has grown comfortable or complacent at the top: The upstart company finally knocked the industry giant off their perch.

Often carries a note of satisfaction at seeing the mighty humbled.
