  Resonant production of color octet electron, e_{8}, at the FCC based ep
colliders has been analyzed. It is shown that e-FCC will cover much a wider
region of e_{8} masses compared to the LHC. Moreover, with highest electron
beam energy, e_{8} search potential of the e-FCC exceeds that of FCC pp
collider. If e_{8} is discovered earlier by the FCC pp collider, e-FCC will
give opportunity to handle very important additional information. For example,
compositeness scale can be probed up to hundreds TeV region.
