Natural new physics has not shown up at experiments so far, motivating the investigation of what the TeV scale could teach us about Nature, independently of a possible naturalness of the Fermi scale. In this talk, I will do so for two cases: i) Dark Matter as a weakly interacting massive particle. I will focus on the reach of telescopes, including CTA, and discuss the example of EW multiplets as DM. ii) Nature is supersymmetric at some higher scale, and SUSY shows up first in the particle of the R-axion. Supersymmetry breaking is in fact typically accompanied by the spontaneous breaking of the U(1)_R symmetry, which to a lesser extent is also explicitly broken. This gives rise to a massive pseudo-Goldstone boson, the R-axion, whose phenomenology has not been explored before at the LHC.
