  This review presents a selection of the final results of searches for various
exotic physics phenomena in proton-proton collisions at sqrt(s)=7 and 8 TeV
delivered by the LHC and collected with the ATLAS and CMS detectors in 2011 (5
fb-1) and in the first part of 2012 (4 fb-1). Searches for large extra
dimensions, gravitons, microscopic black holes, long-lived particles, dark
matter, and leptoquarks are presented in this report. No sign of new physics
beyond the Standard Model has been observed so far. In the majority of the
cases these searches set the most stringent limits to date on the
aforementioned new physics phenomena.
