In some cases, a first encounter with an alien could cause a fear of monsters. ()

A related word to "monster" was "monstrosity", denoting an object that was either overly large and/or hideous. Upon his first sight of Starbase Yorktown in 2263 of the alternate reality, Doctor  called that starbase "a damn monstrosity." ()
