answer: Subject Delta
context: Title: The Saturday Show (ITV TV series)
  Passage: The Saturday Show is Birmingham-based Central Television's flagship Saturday morning kids TV show which replaced their previous show Tiswas.  It ran on ITV for two series between 1982 and 1984.  It was originally planned that popular wrestler Big Daddy would host and that it would be called "Big Daddy's Saturday Show".  A pilot show was recorded with Big Daddy presenting, assisted by Isla St Clair and short films were shot with Big Daddy to insert in the upcoming series; a trailer for "Big Daddy's Saturday Show", complete with logo was shown on ITV the Saturday morning before the show was due to air.  It was then announced during the week that Big Daddy was dropping out and that Isla St Clair would now take the lead, with ex-Magpie host Tommy Boyd assisting and with Jeremy Beadle being used as an occasional "stand in" host.  The actor David Rappaport was also a fixture playing the character "Shades", as was football legend Jimmy Greaves.
  Title: Big Daddy (BioShock)
  Passage: A Big Daddy is a fictional character in the "BioShock" series of video games.  Big Daddies are heavily spliced (genetically mutated and altered with ADAM) human beings who have had their bodies directly grafted into heavily armored, steampunk-inspired atmospheric diving suits.  They are armed with a rivet gun, heavy drill, rocket launcher, or ion laser.  Alpha series Big Daddies are equipped with any of several other weapons as well.  Though they make low-pitched groaning noises similar to whales, Big Daddies have no voice actor attributed to them.  Designed by Irrational Games (then under the supervision of 2K Boston/2K Australia), they first appeared in "BioShock" and were promoted heavily.  A six-inch Big Daddy action figure was included in the limited edition version of the title.  In its sequel, "BioShock 2", the player controls a prototype Big Daddy.
  Title: BioShock 2
  Passage: BioShock 2 is a first-person shooter video game developed by 2K Marin and published by 2K Games.  It is the sequel to the 2007 video game "BioShock" and was released worldwide for Microsoft Windows, the PlayStation 3, and the Xbox 360 on February 9, 2010.  Feral Interactive released an OS X version of the game on March 30, 2012.  Set in the fictional underwater dystopian city of Rapture, the game's story takes place eight years after the events of the first "BioShock".  Assuming control of Subject Delta, a hulking Big Daddy, players are tasked with fighting through "splicers", the psychotic human population of the city, using weapons and an array of genetic modifications.  The game also introduces a story-driven multiplayer mode called "Fall of Rapture", which takes place during Rapture's 1959 civil war, before the events of the first game.
  Title: Veteranz' Day
  Passage: Veteranz Day is the seventh and final studio album by emcee Big Daddy Kane, released on April 28, 1998.  The album came four years after his previous effort, 1994's "Daddy's Home".  "Veteranz Day" received little attention, commercially and critically, and was met with mixed reviews and little sales.  It was his first and only album not to chart on the "Billboard" 200.  "Veteranz' Day" was the first and only album release for the small New York-based record label called the Label Records, which was founded by Frank Yandolino.  Although it managed to earn a distribution deal with Mercury Records by way of Joan Jett's and Kenny Laguna's Blackheart Records, which was acting as a boutique distribution outlet for independent labels from 1998 to 2000, The Label folded almost shortly after the release of "Veteranz Day".  The album features the single "Uncut, Pure," which reached the top 10 on the Hot Rap Singles chart.  There are two versions of "Uncut, Pure"—the original version produced by Easy Mo Bee, and a sequel version produced by Big Daddy Kane himself, the latter of which was released on the independently released 12-inch single and also featured as a bonus track on the CD and cassette versions of the album.
  Title: Big Daddy's Restaurants
  Passage: The first Big Daddy's Restaurant opened in 1964, and was located on Coney Island Avenue in the Sheepshead Bay section of Brooklyn, NY.  It was known to be the only true competitor of Nathan's Famous Hot Dogs.  The driving force behind Big Daddy's success was the partnership of Murray L. Handwerker, the nephew of Nathan Handwerker, founder of Nathan's Famous and Robert "Big Daddy" Napp.
