Please answer the following question: Information: - Tom Swift is the main character of five series of American juvenile science fiction and adventure novels that emphasize science, invention and technology. First published in 1910, the series total more than 100volumes. The character was created by Edward Stratemeyer, the founder of the Stratemeyer Syndicate, a book-packaging firm. Tom's adventures have been written by various ghostwriters, beginning with Howard Garis. Most of the books are credited to the collective pseudonym "Victor Appleton". The 33 volumes of the second series use the pseudonym Victor Appleton II for the author. For this series, and some of the later series, the main character is "Tom Swift, Jr." New titles have been published as recently as 2007. Most of the various series emphasized Tom's inventions. The books generally describe the effects of science and technology as wholly beneficial, and the role of the inventor in society as admirable and heroic. - Roy Rockwood was a house pseudonym used by the Stratemeyer Syndicate for boy 's adventure books . The name is most well - remembered for the Bomba the Jungle Boy and Great Marvel series . - A pen name ("nom de plume", or "literary double") is a pseudonym (or, in some cases, a variant form of a real name) adopted by an author and printed on the title page or by-line of his or her works in place of their "real" name. A pen name may be used to make the author's name more distinctive, to disguise his or her gender, to distance an author from some or all of his or her previous works, to protect the author from retribution for his or her writings, to combine more than one author into a single author, or for any of a number of reasons related to the marketing or aesthetic presentation of the work. The author's name may be known only to the publisher, or may come to be common knowledge. - The pope (from "pappas", a child's word for "father") is the Bishop of Rome and, therefore, the leader of the worldwide Catholic Church. The primacy of the Roman bishop is largely derived from his role as the traditional successor to Saint Peter, to whom Jesus is supposed to have given the keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the church would be built. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI. - A monarch is the sovereign head of state in a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Typically a monarch either personally inherits the lawful right to exercise the state's sovereign rights (often referred to as "the throne" or "the crown") or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may become monarch by conquest, acclamation or a combination of means. A monarch usually reigns for life or until abdication. - A pseudonym (and ) or alias is a name that a person or group assumes for a particular purpose, which can differ from their original or true name (orthonym). Pseudonyms include stage names and user names (both called "screen names"), ring names, pen names, nicknames, aliases, superhero identities and code names, gamer identifications, and regnal names of emperors, popes, and other monarchs. Historically, they have often taken the form of anagrams, Graecisms, and Latinisations, although there are many other methods of choosing a pseudonym. - A regnal name, or reign name, is a name used by some monarchs and popes during their reigns, and used subsequently to refer to them. The term is simply the adjective "regnal", of or relating to a reign, monarch, or kingdom, modifying "name". Since ancient times, monarchs have frequently, but not always, chosen to use a different name from their original name when they accede to the monarchy. The regnal name is usually followed by a regnal number (ordinal), usually written as a Roman numeral (VI rather than 6), to provide a unique identification for that monarch among other monarchs of that realm. In some cases, the monarch has more than one regnal name, but the regnal number is based on only one of those names, for example Charles X Gustav of Sweden, George Tupou V of Tonga. If a monarch reigns in more than one realm, he or she may carry different ordinals in each one, as they are each assigned chronologically, and some realms may have had different numbers of rulers of the same regnal name previously. For example, the same person was both King James I of England (along with Ireland) and King James VI of Scotland. - In modern popular fiction, a superhero (sometimes rendered super-hero or super hero) is a type of costumed heroic character who possesses supernatural or superhuman powers and who is dedicated to fighting crime, protecting the public, and usually battling supervillains. A female superhero is sometimes called a superheroine (also rendered super-heroine or super heroine). Fiction centered on such characters, especially in American comic books since the 1930s, is known as superhero fiction. - A name is a term used for identification. Names can identify a class or category of things, or a single thing, either uniquely, or within a given context. A personal name identifies, not necessarily uniquely, a "specific" individual human. The name of a specific entity is sometimes called a proper name (although that term has a philosophical meaning also) and is, when consisting of only one word, a proper noun. Other nouns are sometimes called "common names" or (obsolete) "general names". A name can be given to a person, place, or thing; for example, parents can give their child a name or a scientist can give an element a name. - Nancy Drew is a fictional American character in a mystery fiction series created by publisher Edward Stratemeyer. The character first appeared in 1930. The books are ghostwritten by a number of authors and published under the collective pseudonym Carolyn Keene. Over the decades, the character evolved in response to changes in US culture and tastes. The books were extensively revised and shortened, beginning in 1959, in part to lower printing costs and to eliminate racist stereotypes, with arguable success. In the revision process, the heroine's original character was changed to be less assertive and more feminine. In the 1980s, an older and more professional Nancy emerged in a new series, "The Nancy Drew Files", that included romantic subplots for the sleuth. The original "Nancy Drew Mystery Stories" series started in 1930, and ended in 2004. Launched that same year, the "Girl Detective" series features Nancy driving a hybrid electric vehicle and using a cell phone. In 2013, the "Girl Detective" series ended, and a new current series called "Nancy Drew Diaries" was launched. Illustrations of the character evolved over time to reflect contemporary styles. The character proves continuously popular worldwide: at least 80million copies of the books have been sold, and the books have been translated into over 45 languages. Nancy Drew is featured in five films, two television shows, and a number of popular computer games; she also appears in a variety of merchandise sold around the world. - The Stratemeyer Syndicate was the producer of a number of mystery series for children, including Nancy Drew, the Hardy Boys, the various Tom Swift series, the Bobbsey Twins, the Rover Boys, and others. - A ring name is a stage name used by a professional wrestler, martial artist, or a boxer.
