Juan travels around the world after stories with Luisa and Jaime and encounters lost races, treasures and so on. He also encountered assorted aliens, monsters, robots, mad scientists, wars, Aztec gods and even had a trip to Hell. The stories are full of gags with him burning his large nose whenever he uses heat vision, of him getting a bump on the head when Luisa hits him, of him hurting his fist when he hits a metal robot. As well as bees, odd-looking little yellow creatures feature in the background in some panels and are revealed as ectoplasms in the "Los Petisos Carambanales" story. He even becomes a popstar and meets the ghost of the Prado Museum. Nothing was too way out for the strips as the characters went from one crazy scenario to another. Often Superlópez not only parodies Superman but also popular literature. This is the case in El Señor de los Chupetes ("Lord of the Pacifiers", a parody for The Lord of the Rings) or Al centro de la Tierra (after Jules Verne's A Journey to the Center of the Earth) From the 1990s Superlópez adventures take place in real scenarios that are drawn using a realistic style. Famous buildings and monuments in Barcelona are often portrayed in detail, as well as those in other cities of Catalonia (Camprodon), Europe (Andorra, Grenoble, Bulgaria) or Japan. As an internal joke, Superlópez says once that his adventures are evolving into simple traveling guides. Superlópez later often had science fiction stories like Tú, robot... (53) where an intelligent robot is created which then travels the world, unintentionally doing good and bad as it seeks to find out what it means to be human. Confronting the robot in the icy wastes, like in the original Frankenstein story, Superlópez is not sure what humanity is either. In El virus Frankenstein (56) a virus changes a young boy into a horrible monster while the El mundo de al lado (57) features a door to another dimension where maybe based on a Little Prince story, the people are enslaved into pulling huge wagons around the planet and Elecciones en Kaxim (58) feature him interfering in elections on a strange alien world. In book 62, Superlópez goes near a beam giant aliens use to cut planets up and his left arm is cut off at the elbow. It suddenly reattaches itself a few pages later
