  Resonant production of leptogluons at the FCC based ep and \mup colliders
have been analyzed. It is shown that e-FCC and \mu-FCC will cover much wider
region of e_{8} and \mu_{8} masses than the LHC. While leptogluons with
appropriate masses (if exist) will be discovered earlier by the FCC pp
collider, lepton-proton colliders will give opportunity to handle very
important additional information. For example, compositeness scale can be
probed up to multi-hundred TeV region.
