  Building from ideas of hypercomplex analysis on the quaternionic unit ball,
we introduce Hermitian, Riemannian and K\"ahler-like structures on the latter.
These are built from the so-called regular M\"obius transformations. Such
geometric structures are shown to be natural generalizations of those from the
complex setup. Our structures can be considered as more natural, from the
hypercomplex viewpoint, than the usual quaternionic hyperbolic geometry.
Furthermore, our constructions provide solutions to problems not achieved by
hyper-K\"ahler and quaternion-K\"ahler geometries when applied to the
quaternionic unit ball. We prove that the Riemannian metric obtained in this
work yields the same tensor previously computed by Arcozzi-Sarfatti. However,
our approach is completely geometric as opposed to the function theoretic
methods of Arcozzi-Sarfatti.
