Commander of the starship Enterprise-D under the command of Captain Jean-Luc Picard. William Thomas Riker was born in Valdez, Alaska, on Earth in 2335. Riker's mother died when he was two years old, and he was raised by his father, Kyle Riker. His father abandoned William at the age of 15, an act that William held against his father until the age of 30, when William and his father were reunited aboard the Enterprise-D. Riker graduated from Starfleet Academy in 2357, and was ranked eighth in his class at graduation. As of 2369, he had been decorated five times.
  Riker's first assignment after graduating from the academy was as helm officer aboard the USS Pegasus, a ship that disappeared in 2358 under mysterious circumstances. Years later, It was reveled that the Pegasus captain, Erik Pressman, had been illegally testing a Federation cloaking device in violation of the Treaty of Algeron. The crew of the Pegasus mutinied to try to prevent Pressman from testing the device. Riker fought to defend his captain, and Riker and Pressman were the only two to escape when the ship apparently exploded. Afterwards, Pressman suppressed all records of the incident.
  Early in his Starfleet career, Riker was stationed on the planet Betazed, where he became romantically involved with psychology student Deanna Troi. Riker, then a lieutenant, chose to make his Starfleet career his priority over his relationship with Deanna, and accepted a posting to the USS Potemking. While aboard the Potemkin, Riker led a rescue mission to the planet Nervala IV and was subsequently promoted to lieutenant commander and commanded for "exceptional valor" during the rescue. It was not realized until years later that a transporter malfunction during the final beam-out caused an identical copy of Riker to be created on the planet's surface. William Riker was later promoted to executive officer aboard the USS Hood, where he served under the command of Captain Robert DeSoto.
  Riker joined the Enterprise-D at planet Deneb IV, after transferred from the Hood.

Data - Lieutenant Commander

Data is a humanoid android, built around 2336 by the reclusive scientist Noonien Sung and his wife, Juliana Soong at the Omicron Theta colony. Data was actually the fifth positronic android constructed by Soong; the first three were unsuccessful. The fourth, the first to become functional, was known as Lore. After Lore's behavior forced Soong to disassemble him, Soong pursued the idea of manufacturing an android free of emotions. Soong hoped this new android would not exhibit the dangerous shown by Lore. Juliana had wanted Data to have a female form, but Noonien, as before, created Data in his own image. Following his activation, Data was much like a boy, though he was made in the form of a full grown adult.
  Data was programmed with the logs and journals of the Omicron Theta colonists in an effort to help Data function better in human society. Unfortunately, before Data could be reactivated, the Crystalline Entity attacked the colony, and Soong and his wife Juliana, were forced to abandon their work. Data remained in a dormant condition, until he was discovered in 2338 by the crew of the Starship Tripoli. Data joined Starfleet and eventually became operations manager aboard the Enterprise-D.
  Data was based on a sophisticated positronic brain developed by Soong. Data's body closely mimicked humanoid form, and contained approximately 24.6 kilograms of tripolymer composites, 11.8 kilograms of molybdenum-cobalt alloys, and 1.3 kilograms of bioplast sheeting. His upper spinal support was polyalloy, while his skull was composed of cortenide and duranium.
  Data served aboard the USS Trieste, and on the Enterprise-D, Data served as operations manager, and was in charge of coordinating the many departments aboard the ship.
  Data always wanted to be human. Although he looks like human, he doesn't completely understands basic things in humanity, like laughter ("The outrageous Okona"). In his effort to be human, he took care of a cat and named him Spot, Data started painting, and writing poetry, like the Ode he wrote about Spot.

 

Crusher, Beverly - Doctor

Cheif medical officer aboard the Enterprise-D. Crusher was born as Beverly Howard in 2324, and graduated from medical school in 2350. She was at the Arvada III colony, and helped her grandmother, Felisa Howard care for the survivors of that terrible tragedy. Although her grandmother was not a physician, she taught Beverly much about the medicinal uses of herbs and roots to help care for the sick and wounded after regular medical supplies had been exhausted.
  Beverly was introduced to her future husband, Starfleet officer Jack Crusher, by their mutual friend Walker Keel. She married Jack in 2348, and they had a child, Wesley, the following year. As a young married couple, Beverly and her husband Jack spent a great deal of time with Jean-Luc Picard. She did not learn until many years later, that Picard had fallen in love with her, but he didn't act on his feelings in order to not betray his friend. Crusher did her internship on planet Delos IV under the tutelage of Dr. Delan Quaice in 2352. Following her husband's death in 2354, Beverly continued to pursue her Starfleet career, attaining the position of CMO aboard the Enterprise-D in 2364. Crusher left the Enterprise-D in 2365 to accept a position as head of Starfleet Medical, but returned to the ship a year later, and was reunited with her son, Wesley.
