Space Invaders (スペースインベーダー, Supēsu Inbēdā) is an arcade video game developed by Tomohiro Nishikado and released in 1978. It was originally manufactured and sold by Taito in Japan, and was later licensed for production in the United States by the Midway division of Bally. Space Invaders is one of the earliest shooting games and the aim is to defeat waves of aliens with a laser cannon to earn as many points as possible. In designing the game, Nishikado drew inspiration from popular media: Breakout, The War of the Worlds, and Star Wars. To complete it, he had to design custom hardware and development tools. It was one of the forerunners of modern video gaming and helped expand the video game industry from a novelty to a global industry (see golden age of video arcade games). When first released, Space Invaders was very successful. The game has been the inspiration for other video games, re-released on numerous platforms, and led to several sequels. The 1980 Atari 2600 version quadrupled the system's sales and became the first "killer app" for video game consoles. Space Invaders has been referenced and parodied in multiple television shows, and been a part of several video game and cultural exhibitions. The pixelated enemy alien has become a pop culture icon, often used as a synecdoche representing video games as a whole.

Spartan X 2 (スパルタンＸ２, Suparutan Ekusu Tsū) is a 1991 beat 'em up video game developed by Tamtex and published by Irem exclusively in Japan for the Family Computer.

Spider-Man is a fictional character, a comic book superhero that appears in comic books published by Marvel Comics. Created by writer-editor Stan Lee and writer-artist Steve Ditko, he first appeared in Amazing Fantasy #15 (cover-dated Aug. 1962). Lee and Ditko conceived the character as an orphan being raised by his Aunt May and Uncle Ben, and as a teenager, having to deal with the normal struggles of adolescence in addition to those of a costumed crimefighter. Spider-Man's creators gave him super strength and agility, the ability to cling to most surfaces, shoot spider-webs using wrist-mounted devices of his own invention (which he called "web-shooters"), and react to danger quickly with his "spider-sense", enabling him to combat his foes. When Spider-Man first appeared in the early 1960s, teenagers in superhero comic books were usually relegated to the role of sidekick to the protagonist. The Spider-Man series broke ground by featuring Peter Parker, a teenage high school student and person behind Spider-Man's secret identity to whose "self-obsessions with rejection, inadequacy, and loneliness" young readers could relate. Unlike previous teen heroes such as Bucky and Robin, Spider-Man did not benefit from being the protégé of any adult superhero mentors like Captain America and Batman, and thus had to learn for himself that "with great power there must also come great responsibility"—a line included in a text box in the final panel of the first Spider-Man story, but later retroactively attributed to his guardian, the late Uncle Ben. Marvel has featured Spider-Man in several comic book series, the first and longest-lasting of which is titled The Amazing Spider-Man. Over the years, the Peter Parker character has developed from shy, nerdy high school student to troubled but outgoing college student, to married high school teacher to, in the late 2000s, a single freelance photographer, his most typical adult role. In the 2010s, he joins the Avengers and the Fantastic Four, Marvel's flagship superhero teams. In recent storylines, Peter Parker dies while his mind is in the body of his enemy Doctor Octopus; Doctor Octopus then lives on inside of Parker's body, taking the role of Spider-Man in The Superior Spider-Man (2013–present). However, on January 11, 2014, it was officially confirmed that the character will return in April 2014. Separately, Marvel also introduced a new Spider-Man, the mixed race teenager Miles Morales, in stories set in its Ultimate Comics-branded alternative universe. Spider-Man is one of the most popular and commercially successful superheroes. As Marvel's flagship character and company mascot, he has appeared in many forms of media, including several animated and live-action television shows, syndicated newspaper comic strips, and a series of films starring Tobey Maguire as the "friendly neighborhood" hero in the first three movies. Andrew Garfield has taken over the role of Spider-Man in a reboot of the films. Reeve Carney stars as Spider-Man in the 2010 Broadway musical Spider-Man: Turn Off the Dark. Spider-Man placed 3rd on IGN's Top 100 Comic Book Heroes of All Time in 2011.
