This work reports on models described by two real scalar fields coupled with gravity in the five-dimensional
spacetime, with a warped geometry involving one infinite extra dimension. Thick branes can have internal
structure and be generated by two-kink solutions, possessing the advantage of bringing room for the presence of
nontrivial structures inside the brane. It provides a richer treatment for the system under consideration, since
it allows the manifestation of branes hosting internal structure. Furthermore, there is another context of brane
world characterized by a hybrid behavior, which occurs when the scalar source supports localized structure
with compactlike profile. In such scenario, it is manifested a thin brane behavior when the extra dimension
is outside a compact domain, while a thick brane is revealed inside the compact region. In particular, it is
possible to propose a route that smoothly goes from kinks to compactons, leading to a braneworld formulation
generated by compact-like defects; which one reveals a hybrid brane configuration. Through a mechanism that
smoothly changes a thick brane into a hybrid brane, one investigates the appearance of hybrid branes hosting
internal structure, characterized by the splitting on the energy density and the volcano potential, induced by a
parameter which one controls interactions between the two scalar fields. In particular, we investigate distinct
symmetric and asymmetric hybrid brane scenarios.
