  In this article, we give the exact interval of the cross section of the
Multibrot sets generated by the polynomial $z^p+c$ where $z$ and $c$ are
complex numbers and $p \geq 2$ is an even integer. Furthermore, we show that
the same Multibrots defined on the hyperbolic numbers are always squares.
Moreover, we give a generalized 3D version of the hyperbolic Multibrot set and
prove that our generalization is an octahedron for a specific 3D slice of the
tricomplex polynomial $\eta^p+c$ where $p \geq 2$ is an even integer.
