  The presence of phantom dark energy in brane world cosmology generates
important new effects, causing a premature Big Rip singularity when we increase
the presence of extra dimension and considerably competing with the other
components of our Universe. The idea is based first, in only considering a
field with the characteristic equation $\omega<-1$ and after that, consider the
explicit form of the scalar field with a potential with a maximum (with the aim
of avoid a Big Rip singularity). In both cases we study the dynamic in a robust
form through the dynamical analysis theory, detailing in parameters like the
deceleration $q$ and the vector field associated to the dynamical system.
Results are discussed with the purpose of deeming the cosmology with a phantom
field as dark energy in a Randall-Sundrum scenario.
