Abstract: Dark Matter may not be an elementary particle but rather bound states of strong interactions similar to hadrons in QCD.  It is actually desirable if we want dark matter to be self-interacting to address the core/cusp issue.  It could be dark pions that undergo freeze-out by 3->2 annihilation.  It could also be dark baryons that come together with the baryon asymmetry in the Standard Model.  I will present explicit models in each case, and discuss future experimental probes, in particular Belle II and Prime Focus Spectrograph on the Subaru telescope.
