  The recent study of holographic superconductors has shown the emergence of a
Kasner universe behind the event horizon. This paper serves to add to the
discussion by introducing two modifications to the holographic superconductor
model: an axion field term and an Einstein-Maxwell-scalar (EMS) coupling term.
We first discuss the effect the modification parameters have on the condensate
then explore the black hole interior dynamics. Features previously identified
in the interior are found in the model presented, including the collapse of the
Einstein-Rosen bridge, Josephson oscillations and Kasner
inversions/transitions. However, we find that by increasing the EMS coupling
parameter, the collapse does not occur near the axion-Reissner-Nordstr\"om
horizon and the oscillations are no longer present; the geometry entering into
a Kasner regime after a large-$r$ collapse instead.
