  In this article, we test the possibility of building new black-bounce
spacetimes with changes in the area in the context of general relativity in
four dimensions. These new metrics can present extra structures, such as
anti-throats. We see two regions where the area goes to infinity, and,
depending on the model, one of these regions presents curvature singularities.
Regular metrics can be extended to negative values of the radial coordinate and
have a symmetrical structure, whereas some singular cases cannot be extended
and have no symmetrical structure. The energy conditions are analyzed, and, for
some cases, at least one of the inequalities in the null energy condition is
not respected. We also presented models that satisfied the null energy
condition outside the event horizon. The event horizon hides the throats of
these models.
