In the era of TeV observatories, Multi-TeV Weak Interactive Massive Particles (WIMPs) are interesting dark matter candidate, among others. I will present an overview on this topic, including some recent results and new research prospects. In particular, I will show that a black-hole-induced DM-spike of Multi-TeV WIMPs well fits the Galactic Center cut-off detected by HESS in the gamma rays. Nonetheless, we can set further constraints on the WIMP DM mass and annihilation cross section via the study of both multi-messenger and multi-wavelength signals from several astrophysical targets, e.g. recently proposed dwarf irregular galaxies. Finally, I will briefly introduce the branons as extra-dimensional Multi-TeV dark matter candidates.
