Bionicle (stylized as BIONICLE) was a line of contraction toys created by the Lego Group marketed primarily for 5-to-16-year-olds. Originally a sub-theme of Lego's Technic series, the line was initially launched in early 2001 in Europe and Australia and the following summer in North America and over the following decade became one of the Lego Groups's biggest-selling properties. The theme's concept is based on two earlier Lego themes that featured characters based on classical elements and incorporated a similar building system. In 2009, The Lego Group closed down the production of future Bionicle sets due to a lack of new sales in the product, and in the wake of theme's cancellation "replaced" Bionicle with Hero Factory; a new contraction series that carries Bionicle's legacy and features a similar building system. The Bionicle story is set in a science fantasy universe in a time pre-dating recorded history, featuring part-organic, part-machine sapient beings and is told on a vast multimedia scale through comic books, video games, website content, feature-length films and primarily, the sets themselves, among other media types. Between 2001 and 2003, the story depicted the events of six heroic beings called Toa Mata (later Toa Nuva), who with great 'Kanohi' masks of power and the ability to control different elements, protected the villagers known as Matoran on the tropical island of Mata Nui against an evil being known as the Makuta (real name later revealed as Teridax) and his many threats. The setting shifted in 2004 and 2005 to the futuristic city island of Metru Nui in a prequel storyline explaining the origins of the Matoran. 2006 began a new story focusing on the quest for the legendary Mask of Life; an artifact said to be able to save the Great Spirit Mata Nui (the god-like entity the Matoran worship) who was originally put to sleep by Makuta. The story culminated in 2008 with the revelation that Makuta Teridax had taken over Mata Nui's body - revealed to be a giant robotic humanoid vessel that houses the homelands of the Toa, Matoran and other known 'bio-mechanical' beings - and placed Mata Nui's consciousness in the Mask of Life, ejecting it into outer-space. 2009 began what was originally intended to be a new saga in the Bionicle story; the former Great Spirit Mata Nui crash-lands on the desert world of Bara Magna after being banished from his own universe by Makuta Teridax. There, he forges new friendships with the planet's Glatorian and Agori residents while attempting to find a way back to his homeland to save the Matoran from Teridax's tyrannical rule. After the announcement of Bionicle's cancellation, the 2010 storyline was changed to Teridax arriving on Bara Magna and battling Mata Nui as well as the former completing his destiny of reforming Spherus Magna; the once-plentiful planet that used to be Bara Magna. The story ended with Mata Nui retreating back inside the Mask of Life, deciding to let the Toa, Matoran, Glatorian and Agori build a new society together without him.

Bionicle Heroes is a 3D third person shooter video game. The game was released in November 2006 by TT Games on PlayStation 2, Xbox 360, Nintendo GameCube, Microsoft Windows and by Amaze Entertainment on Game Boy Advance, and Nintendo DS, a Nintendo Wii version was later released in April 2007. The game stars Bionicle's 2006 feature characters, the Toa Inika and the Piraka. However, the game also features enemies from previous games. Players must destroy enemies, solve puzzles in order to progress further, and throughout the game, maximize their individual special powers and gain better and deadlier weapons. While the game is loosely based on the first part of the Bionicle Legends story arc; it is non-canonical and features several characters from previous arcs in the franchise. The Nintendo DS version of Bionicle Heroes is in the first-person perspective instead of third-person, and is the first LEGO game to be rated T for Teen. The Game Boy Advance version is also vastly different, having a top-down perspective instead of over the character's shoulder.

Blackthorne (Blackhawk in some European countries) is a cinematic platformer video game developed by Blizzard Entertainment. It was released for the SNES and MS-DOS in 1994, and with enhanced graphics and a higher color palette for the Sega 32X in 1995 and for Mac OS in 1996. A port to the Game Boy Advance was released in 2003, also with a brighter palette than original versions. Because of GBA's fewer number of buttons, some actions were set to combinations of buttons. In 2013 the game was added to Battle.net as free download emulated through DOSBox.

The game was released in North America in November 1988 and in Europe on April 25, 1991 (1991-04-25). The game is the first in the Blaster Master series, and it spawned two spin-off titles as well as two sequels. The game features a character named Jason who follows his pet frog Fred down a hole in the earth. There he finds a tank and uses it to battle radioactive mutants. The player controls Jason and the tank SOPHIA THE 3RD through eight levels of gameplay to find the whereabouts of Fred and to defeat the mutants and their leader, the Plutonium Boss. The game was praised for its smooth play control and level designs, detailed and clean graphics, and music, and it was criticized for its high difficulty level and lack of passwords or save points. The game was novelized by Peter Lerangis, as part of the Worlds of Power series published by Scholastic Books.

Bob the Builder is a British children's animated television show created by Keith Chapman. In the original series Bob appears as a building contractor specializing in masonry in a stop motion animated programme with his colleague Wendy, various neighbours and friends, and their gang of anthropomorphised work-vehicles and equipment (all made of clay). The show is broadcast in many countries, but originates from the United Kingdom where Bob is voiced by English actor Neil Morrissey. The show was later created using CGI animation starting with the spin-off series Ready, Steady, Build!. In each episode, Bob and his group help with renovations, construction, and repairs and with other projects as needed. The show emphasizes conflict resolution, co-operation, socialization and various learning skills. Bob's catchphrase is "Can we fix it?", to which the other characters respond with "Yes we can!" This phrase is also the title of the show's theme song, which was a million-selling number one hit in the UK.
