Rius (aka: Eduardo del Rio) is a Mexican cartoonist born in 1934. He has published over a hundred books on several topics including history, politics, religion and vegetarianism.

Originally from Michoacán, Rius trained as a teenager to be a Catholic priest (of all things!). Dropping out of the seminary, he then moved to Mexico City where he held a series of odd jobs. He became a cartoonist and started out drawing traditional one or two panel strips for Mexican humour magazines in the [[TheFifties 1950s]]. Eventually he created his series ''Los Supermachos'' in the [[TheSixties 1960s]] and ''Los Agachados'' in the [[TheSeventies 1970s]], both series had their own magazines and were set in rural Mexican villages. He cemented his fame after publishing in 1966 ''Cuba para principiantes'' (Cuba for Beginners) which was the first of his general knowledge books. The latter were published in a small graphic novel format but their bent was didactic rather than narrative, with the plot very much in the background (if at all existent). Except for the ''Supermachos'' series and his earlier strips, all of Rius's work includes collage as his signature illustrating technique.

A staunch leftist activist and former communist, Rius's books continue to be popular in Mexico and many of them have been translated into several other languages. His works have earned him awards and recognition in the medium internationally. Many of his comic books can be found translated into English on Amazon.com.

His books are known for their humor and simplicity, in an attempt to reach as wide an audience as possible, in fact his works have actually helped many people to understand the fundamental differences between capitalism and socialism/communism.

Compare to Creator/JackChick, another cartoonist that uses comic strips [[AuthorTract to convey his ideology]], albeit a diametrically opposed one.
* AfterTheEnd: During the ColdWar Rius always [[{{TheGreatPoliticsMessUp}} predicted an eventual communist victory]]. Well, since the fall of the Berlin Wall Rius has kept publishing in books and magazines anyways.
* TheAlcoholic: Nopaltzin.
* AllNaturalSnakeOil: Several of his books dedicated to naturism/vegetarianism/herbal medicine/anti-pharmaceutical/anti-food industry come across as this, almost always ending with he phrase "The best thing is always the natural".
* [[AmericaSavesTheDay America Screws The Day]]: Oho boy... the guy is fervently anti-American, essentially blaming the country for every ill in the world, from the poverty on ''your'' country to obesity.
* AncientConspiracy: Sort of, if you believe that humanity has always been dominated by the same group of people with the same special interests (the ruling class, who wish to exploit the rest).
* ArmiesAreEvil: ''Especially'' if its the [[EvilArmy U.S. army]].
* ArsonMurderAndJaywalking: "Money is power, with it capitalists can bribe, ransack poor countries, exploit workers, swindle people and... [[FelonyMisdemeanor do business.]]"
* ArtisticLicenseBiology: From ''The Illustrated Herbalist'': "Wild animals use herbs to treat themselves, and you can't say that the animals are sick".
* ArtisticLicenseMedicine: He has a tremendous distaste for traditional medicine, and is a very strong advocate of homeopathy and naturopathy, recommending them above traditional medicine.
* ArtisticLicenseEconomics: Unfortunately, economics is not an area of his strength, as he is shown committing every [[UsefulNotes/{{Economics}} economic fallacy]] and even getting the terminology wrong (like confusing Protectionism with Autarchy). Even he in the early 2000's admitted that Economics is a complex subject and his knowledge is limited.
* ArtisticLicenseHistory: While many of his books are [[ShownTheirWork well-researched]], there are many cases of historical innacuracies, like claiming that the Roman Empire fell because the slaves rebelled, his reading of U.S. history gives the impression that it was all a MasterPlan of some people for [[TakeOverTheWorld world domination]] and that no event in the past century did not involve the U.S.A. somehow.
* AuthorFilibuster: When parts of a book have a plot there will be inevitably one point in which Gumaro or any other character will start elaborating and/or preaching about the point of the chapter.

* BrokenPedestal: To UsefulNotes/FidelCastro as expected.
* ChewbaccaDefense: When he tries to defend the Aztec's human sacrifices by saying that they were no worse than the European Inquisition.
* ConspiracyTheorist: Some of his books regarding religions and sects can portray him as this, since they show [[RussiaIranDiscoSuck different religions with diametrically different sets of beliefs but all allied with the masters and the World's Status Quo]].
* CorruptBureaucrat: Trastupijes.
* CorruptChurch: Pretty much how he portrays any organized religion with special emphasis on the Catholic church.
* CorruptCorporateExecutive: Again, how he portrays anyone that is a capitalist.
* CorruptPolitician: Practically any politician in the real world not showing socialist tendencies but for an in-universe example we have Don Perpetuo del Rosal.
* CrapSaccharineWorld: After the Communism's collapse all Socialist countries were [[{{Retcon}} Retconed]] as this.
* DirtyCommunists: Subverted and repeatedly denied.
* DoubleStandard: Before the fall of the Berlin Wall, he widely criticized the U.S. government and Western powers, mentioning almost nothing bad from the socialist states of the time. He admitted this later, saying that he "Didn't want to provide ammunition for Imperialism".
* EagleLand: Type 2.
* TheEvilEmpire: The U.S.A.
* FelonyMisdemeanor: According to him: If you own a business and have people working for you, you are a dirty exploiter of human lives.
* TheFundamentalist: Doña Tecla.
* TheGreatPoliticsMessUp: BIG TIME.
* HistoryMarchesOn: Several of his books have been edited in later editions to reflect the exposure of several historical facts, like some [[KickTheDog less-than-honorable acts]] by UsefulNotes/CheGuevara, Trotsky's role in the Russian Revolution followed by his later exile, the publication of the KGB archives and so on.
* LaymansTerms: That's the intention of his comic strips and books.
* LiesDamnedLiesAndStatistics: The most egregious examples of this are his books against the food industry, and his claims on how the food preservatives are poisoning us, usually goes as this:
-->'''Straw Ignorant:''' That's exaggerated! If that were true we would all be dead.
-->'''{{Author Avatar}}:''' Not dead, but sickened. Have you noticed the growing trend on ?
* NebulousEvilOrganisation: Above all, the [=CIA=]; But ''any'' big, transnational business company also qualifies and of course the Catholic Church.
* OldShame: His first book on the Cuban Revolution, another dedicated to the (East) German Democratic Republic, and practically any book that prophesied the fall of capitalism and the rise of communism. Even he acknowledges this.
* OutgrownSuchSillySuperstitions: All the good guys of his strips have, and he devotes a [[AuthorTract lot of books]] to try to convince you of doing the same.
* TheRevolutionWillNotBeVilified: As mentioned before, this was his treatment of any Communist revolution with special emphasis on the Cuban Revolution, he even justified and praised this in ''Cuba Libre'' (Free Cuba): "The (Cuban) government tolerates anything to the press... [[NoExceptYes except criticizing the Revolution.]]"
** TheRevolutionWillNotBeCivilized: And after the end of the ColdWar this became the new treatment.
* RussiaIranDiscoSuck: See ConspiracyTheorist.
* SideEffectsInclude: He frequently bashes the pharmaceutical industry for this reason, arguing that all traditional medicines have dangerous side effects, while painting herbal medicine as a safe alternative, on virtue of being "all natural".
* ScienceMarchesOn: The first edition of the book dedicated to AIDS contains a lot of outdated information, like warning that the HIV could be acquired by insect bites, and presents the ConspiracyTheory of AIDS originally being a bio-weapon developed by the Reagan's administration as fact, later editions have more updated facts.
* SinisterMinister: Played straight with his portrayal of Catholic high hierarchy, but surprisingly averted with the low one: There is the Gary Stu'ish, recently ordained, young progressive priest and the older, more conservative one of the town, even the latter is portrayed sympathetically in some strips.
* StrawmanPolitical: Played straight with his portrayal of [[CorruptCorporateExecutive capitalists]] and Americans.
* TakeThat: To other cartoonists and authors with more conservative views (and anyone that advocates for free market for that matter).
* TakeThatMe: "If you want to continue eating in peace, don't read my petty books".
* {{Veganopia}}: Besides his old communist sympathies, Rius is known as a passionate vegetarian; half or more of his most recent work is about nutrition.
* WhyWeAreBummedCommunismFell: One would think so but it's reasonably averted since Rius has been quite a sport about being on the losing side of the ColdWar (he's still a left winger though, and his most recent work shows it).
* WrittenByTheWinners: The mantra he recites regarding the official account of historical events.
* YourTerroristsAreOurFreedomFighters: Subverted with his treatment on TheWarOnTerror, where he basically says that the 9/11 terrorists are no worse than the U. S. and that the war on terror is basically EvilVSEvil.
