Fake xWSS
A fake or counterfeit xWSS is a spaceship in a cellular automaton other than Conway's Game of Life, that matches Life's lightweight, middleweight or heavyweight spaceship in at least one of its phases but evolves differently. Whereas the xWSSes in Life have period 4 and move orthogonally at c/2, fake xWSSes can have different periods and move in different directions at different speeds.
Examples
The c/2 orthogonal spaceship with the apgcode xq4_6frc in the non-totalistic rule B3/S23-ijn4a is a fake LWSS, even though it moves at the same speed, has the same period, and each of its phases can be reoriented to match a phase of the standard LWSS:

A c/32 diagonal LWSS with an apgcode xq32_79v in the non-totalistic cellular automaton B34et5-any8/S234e5ey6i moves at a slower speed and diagonal. One phase is the same as one phase of the standard LWSS:
