Searches for exotic particles in $e^{+}e^{-}$ collisions with the DELPHI detector

Results of searches for exotic particles by the DELPHI Collaboration at CERN are presented. Highlights from the searches for Flavor Changing Neutral Currents, Technicolor, Fermiophobic Higgs and Compositeness, in the LEP 2 data are shown. No evidence for new physics was found and the excluded regions of the parameter space for each model are presented. (7 refs).
