by secooper87 is a long Inter Continuity Crossover series between Buffy the Vampire Slayer and Doctor Who, and later with their respective spinoffs Angel and Torchwood. It begins one night in 1998, as Buffy Summers patrols the Sunnydale graveyard and discovers a man in a pinstripe suit and trainers chatting up a vampire...Canon compliant with the televised Buffy and Doctor Who franchises, but not with their various non-televised Expanded Universe works. To clarify, The Adventures of a Line Hopper is the name of both the first set of stories and the series overall. The series can be divided into two parts:
The Adventures of a Line Hopper
- Buffy Summers attempts to discover the secret of her connection with this mysterious "Doctor".
The Child of Balime (Split into 4 "seasons") primarily chronicles the adventures of Seo, a new time traveler introduced at the end of Line Hopper and the daughter of Buffy and the Doctor.
- The 1st "season" primarily features the Buffyverse characters at the start of Torchwood in 2007.
- The 2nd "season" primarily features Seo's travels through time
- The 3rd "season" primarily features Buffy's mysterious illness and Seo and Jenny's regenerations.
- The 4th "season" primarily focuses on Seo's relationship with the Doctor and continues the arc started in the 3rd "season"

After Reunion, the series will restart into a new series featuring the Original Characters of Line Hopper, while removing a majority of the Buffy and Doctor Who elements and characters.
The tropes appearing in Adventures of a Line Hopper are:
- Disney Death: Allison in Four Five Six. Almost all of the major characters on the real world side of The Years That Never Were. They did in fact actually die, but everyone killed comes back once time is reversed.
- Distressed Dude: The Doctor gets kidnapped/brainwashed/etc a handful of times, and usually either has to be rescued or has to carefully make use of Timey Wimey to get others to help him escape.
- Doppelgänger Crossover: Though they never meet, Spike and John Hart (both played by James Marsters) are both recurring characters.
- Evil Me Scares Me: Buffy and Elizabeth.
- Though more insane than evil, Dawn is terrified of Tenth!Seo and decides to leave First!Seo for a time because of it.
- A God I Am Not: Played for laughs in the epilogue of "The Seventh Segment," where after five thousand years Glory's Minions still think that the Doctor is God despite his "first commandment" being "What? No! I'm not God! Stop Worshipping Me!"
- God for a Day: Tenth!Seo gets a taste of Glory's true power in her home universe.
- Heroic Sacrifice: Seo flings herself off of the bridge of the Valiant near the end of the Year that Never Was in order to prevent the Master from using her to kill Martha Jones.
- The Incorruptible: The Doctor may do horrible things to prevent worse tragedies, but he will always take the course of action that leads to the best possible outcome, and will always attempt to Take a Third Option before taking the Lesser of Two Evils. It's implied that part of this is because he feels guilt over every atrocity he commits, no matter how justified or unavoidable. So much so that even as a vampire, he still tries to do the right thing and ultimately pulls a Heroic Sacrifice despite lacking a soul.
- Lack of Empathy: The reason why the Powers That Be refer to The Embarrassment as such- a being of their strength having a human soul is considered an embarrassment to their kind.
- Patchwork Kids: Seo, who is essentially a combination of Buffy's skill with The Doctor's intelligence, with a combination of the love of life and adventure from both. Her first incarnation is even described as looking exactly like Buffy with the Tenth Doctor's eyes and dimples. Justified, in that Seo was purposefully designed by the Monks of Dagon to incorporate the best traits of the two in order to combat Glory.
- The Meddling Kids Are Useless: Since the author strictly follows any canon events, characters from Buffy/Doctor Who will always find themselves unable to make a difference in any pre-established Doctor Who/Buffy episodes.
- Mental Affair: How Time Lords usually have sex. Later Seo and Xander break up because he lacks her telepathic abilities.
- Powers That Be: The Powers That Be from Buffy the Vampire Slayer and Angel. Also Seo's adoptive Father, Bad Wolf/The Embarrassment/The Entity.
- Rape Is a Special Kind of Evil: Only three enemies have this particular mark on their rap sheets, and all three die (or worse):
- The Master (well, Mind Rape, which is considered the standard Time-Lord equivalent of sex)
- Bilis Manger (who is thoroughly insane and convinced that Seo is his lover, despite the fact that apart from a one-night stand they've never had sex without him telepathically manipulating her into it)
- Razor and his allies (soulless vampires whose actions push the Doctor into committing genocide against all vampires on Earth)
- Take Up My Sword: Seo promises to uphold Buffy's world-saving after she believes that she's left her to die in another universe.
- Tomato in the Mirror: Seo is the mind of Glory, in other words she is the TRUE Glorificus while the one Buffy faced was merely the shell of her body.
- Truly Single Parent: Rose Tyler/Bad Wolf created the Entity AKA the Bad Wolf, AKA The Embarrassment out of uncontrolled raw reality-warping power and the wish to protect the Doctor- hence why the Entity looks like nine.
- Tyke Bomb: The reason why Seo is so dangerous. The Most Dangerous Alien You'll Ever Meet has the Torchwood team explaining to Gwen that despite being raised properly, Seo has too much power and potential for destruction for a teenager to handle (therefore making her The Most Dangerous Alien You'll Ever Meet).
