Phantom of Truth is a Danny Phantom fanfic posted to FanFiction.net by user HaiJu. The official summary: Locked away in a secret government lab with Phantom as her subject, nothing stands between Maddie and the truth... except, perhaps, herself.
A sequel, Shadow of a Doubt, was completed in 2017, a Doorstopper of over 300,000 words - nearly five times the length of the original.
Phantom of Truth contains examples of:
- An Arm and a Leg: A major turning point in the story occurs when Maddie cuts off Phantom's hand.
- Appendage Assimilation: Fortunately, the removed hand can be reattached.
- Darker and Edgier: Than the series it's based on. There are parts that are far too bleak or gruesome for a Nicktoon.
- Electric Torture: A frequent tactic for keeping Phantom in line.
- Epigraph: Each chapter begins with a quote.
- Escaped from the Lab: By the end of the story, with Maddie's help.
- Inhumanable Alien Rights: There's nothing illegal going on here.
- Motherly Scientist: Maddie, eventually.
- Playing with Syringes: The experiments run on Phantom and other ghosts don't follow the usual rules of ethics.
- Strapped to an Operating Table: What would a GIW fic be without it?
- They Would Cut You Up: It seems Danny's canon fear of becoming a lab rat was justified.
- What Measure Is a Non-Human?: How Maddie, and the rest of the GIW, justify their treatment of ghosts.
