"Doctor Who writer Robert Banks Stewart has hinted that fans should expect a multitude of monsters in the 50th special. Stewart created shape-shifting aliens the Zygons, who have been confirmed to return in the anniversary episode.   &amp;quot;The Zygons are in there with all the others - particularly the Daleks and the Cybermen,&amp;quot; Banks Stewart - who was promoting his new crime thriller novel The Hurricane&amp;#039;s Tail - told Digital Spy. &amp;quot;[But] nobody yet knows what the plot of the 50th will be - Steven Moffat and his team in Cardiff, they are quite rightly keeping it all secret.&amp;quot;  Banks Stewart previously penned classic Who stories &amp;#039;Terror of the Zygons&amp;#039; (1975) and &amp;#039;The Seeds of Doom&amp;#039; (1976). However, the writer explained that while he agreed to let the BBC use his creations, he feels the current Doctor Who episodes are &amp;quot;too adult&amp;quot;. &amp;quot;My own personal opinion is that the modern Doctor Who should be aimed more at children,&amp;quot; he said. &amp;quot;People very fondly remembered being scared by Doctor Who - now the plots seem to me a little too adult.&amp;quot; The Hurricane&amp;#039;s Tail is available now, priced \u00A39.99 in paperback and \u00A35.99 as a Kindle ebook.
