The composite models are among the promising theories to explain the open questions of the Standard Model in particle physics. Many of these models allow particles carrying both lepton number and color, e.g., leptoquarks and leptogluons. Sometimes also color-singlet leptohadrons can be accomodated. I will discuss possible effects of some of these new composites at the LHC, and in the generation of the baryon asymmetry of the universe and the neutrino masses.
