Only his paternal surname is a matter of public record, Aguilar Leos, as his brother's real name, Juan Aguilar Leos, is publicly known. My Annoying Brother (); lit.

He is best known as a member and one of the main vocalists of the South Korean-Chinese boy group EXO.

Georgia "George" Fayne is a character in the popular "Nancy Drew Mystery Stories" series.  She is one of Nancy's best friends and cousin of Bess Marvin.  Her real name is Georgia, although no one calls her that except her parents.  (This is a change made in the 1980s; one volume, "The Clue in the Old Stagecoach" in 1960, mentioned her real name as Georgia on the title page, but this was altered after the first few printings.  In the original novels her name was just George, named for her grandfather, with, depending on the ghostwriter, a chain of either boys or girls ahead of her.)  She has short black hair and brown eyes.  She is an athletic tomboy, and is not easily scared when involved in Nancy's sleuthing.  Her boyfriend is first a friend of Ned Nickerson's named Buck Rodman; she later dates Burt Eddleton.  Bess and she were introduced to readers in "The Secret at Shadow Ranch".  In the "Nancy Drew Girl Detective Series", she has a little brother named Scott.  In the original version of "The Ringmaster's Secret", she has a nephew, indicating there are other siblings.  A change in ghostwriters in 1933 resulted in George and her cousin Bess both being indicated as only children; their siblings, if there are any, are omitted from a will where their names are read.  This can be explained in the text by assumption that they were the only children of their mothers known to their benefactor personally ("The Sign of the Twisted Candles").  With Nancy, George and Bess encountered an elderly man who was a distant relation, and showed friendliness and compassion toward him.  As such, they may have been named; it was an oddity in the series.

Isen "Ice" Sulejmani (The Beast's brother) is another past member; he was left out of the formation in 2006 because the group wanted a more serious image.  After putting out materials online via their MySpace account, they released their debut album "Återfödelsen" with collaborations from Gonza, Afasi, Organism12, Masse, Keione, AFC, Timbuktu, Chords, Hosam (from Highwon), Avastyle and Rock-a-spot.

Brian Helicopter is the stage name of Gareth Holder (born 27 June 1958, Leamington Spa), an English musician, based in the United States.  He is best known for playing bass guitar for the UK punk rock band The Shapes.  He also played for many other bands, the most notable being the NWOBHM bands Rogue Male and HellsBelles.  For a short time in the early 1980s, he was also a member of British R&B band The Mosquitos, with guitarist Steve Walwyn of Dr. Feelgood and Eddie and the Hot Rods, and can be seen on the cover of The Mosquitos only single "Somethin' Outta Nothin'".  A prolific session player, he appears both credited and uncreditied on many releases throughout the 1980s and early 1990s under both his real and stage name.  He was one of the first bassists in the nascent UK punk scene to adopt the Rickenbacker bass guitar which he still uses to this day.  He was also one of the first bass guitarists in the world to use Trace Elliot amplification.  His bass playing style is characterized by a very fast precise pick attack, and fast runs.  Unusually for a bass guitarist, he sometimes utilizes an overhand tapping technique more common to six string players.  He continues to play professionally, reverting between his real name and his stage name as the fancy takes him.  He is also a professional skydiving coach and instructor, currently holding seven world records in the sport.  He can be seen in an episode of MythBusters aired on the Discovery Channel taking presenter Kari Byron skydiving whilst testing the falling airplane blue ice myth.  He is also a vegetarian.  He can be seen in the independent film Six Sex Scenes and a Murder, in the role of the bounty hunter.  He currently resides in California, where he plays bass for the San Francisco Bay Area band Ghosthookers.  Ghosthookers released a record in 2008 which features Brian Helicopter on bass under his real name.
