Child Popstar: Released his debut album at age fifteen, and was playing guitar and singing at least two years before then.
Christmas Songs: Played straight with many of his Christmas covers, including Slade's "Merry Xmas Everybody". Subverted with one of his original songs, "Betty Ford For Xmas", about life as a drug user.
Cloudcuckoolander: Plays up this within his projected image and shows shades of this in real life as well.
He's also covered "Singin' in the Rain", "Bad to Me", "California Girls", "Put Your Head on My Shoulder", "Johnny B. Goode", "That's All", "Stuck in the Middle With You", the list goes on...
Plus he's covered songs like "Lola", "Hot Blooded", "Home Sweet Home", "Sky High", "The Final Countdown" and "Play That Funky Music (White Boy)" for iTunes releases.
And that's not even going into the covers he's done live.
Creator Backlash: Despite openly saying he doesn't care for "I Was Made For Dancin'", he's still known to frequently perform it live, for the sake of his former teenage fanbase attending his concerts for nostalgia. His dislike of the song has caused him to sometimes reappropriate it is an acoustic ballad or a straight-up rock song.
Creator Breakdown: His legal troubles have unfortunately earned him more airtime than his creative endeavours in the past decade and-a-half.
Fake Brit: Affects a British accent in some of his songs, most noticeably in "Same Goes For You."
Former Child Star: Parodied in his role on Dickie Roberts: Former Child Star. He even sings a song on the soundtrack with this trope almost word-for-word as its very title, and contributes vocals to the song "Child Stars on Your Television".
Guy Liner: Is almost never seen without wearing eyeliner nowadays.
Lyrical Dissonance: "Symptoms". The song speaks of a dying relationship to an upbeat soundtrack.
Meaningful Rename: After his father had left the family, Leif's mother suggested he change his name for his burgeoning acting career. He initially went by 'Leif Per' (Per is his middle name), but found that casting agents had trouble pronouncing it. One day he received a paycheck that was accidentally addressed to a 'Leif Garrett'. After he and his mother discovered that the name 'Garrett' meant 'mountain' and denoted strength, he then decided to adopt that name.
Then again, Feel The Need was this to Leif Garrett. The disco sound was adopted in favour of the Power-Pop, Pop-Rock treatment of covers used beforehand. His subsequent Teen Idol catalog had a mixture of both sounds.
Nice Guy: Despite his rather troublesome life, he's softly-spoken, always has time for the fans, and is said to be one of the most genuine and sweetest guys in show business. It's also the reason why his subsequent breakdown took many by surprise.
Reality Subtext: In the 1985 movie Thunder Alley, Garrett plays the frontman of a rock band who is pushed aside for a younger, more promising guitarist. On top of that, the group is torn apart by drugs. Hmmmm...
His character in The Outsiders, Bob Sheldon, is a heavy drinker.
