Celestia leaves to go on sabbatical, but disappears without a trace. Luna asks Twilight to look into her disappearance. A decade later Twilight gets a message claiming to be from Celestia, Rainbow takes her to Canterlot where they meet up with Luna. They discover a hidden workstation where Twilight accidentally triggers a device that zaps Rainbow into a virtual recreation of Equestria, where she soon meets up with Celestia and encounters an enemy she never expected.
PONY Legacy is a fanfic by RBDash47 that is a crossover with TRON: Legacy, though none of the characters from the film appear.
PONY Legacy contains examples of:
- Adapted Out: Most of the vehicles, such as the Light Cycles, Recognizers, Tanks, Ships, and the Solar Sailer, which is replaced by a train.
- Adaptational Heroism: Jewel (Gem), and Shy (Jarvis).
- Adaptational Species Change: Due to the ISOs being Adapted Out, Spark (Quorra) is a regular program.
- Anti-Villain: Shy, who only serves RBD out of a sense of misguided loyalty and later performs a Heel–Face Turn.
- Decomposite Character: Sam’s role is split between Twilight and Rainbow.
- Death by Adaptation: APP (Tron) is killed by RBD.
- Spark (Quorra) stays behind in the grid and gets derezzed when the corruption reaches her.
- The Grid itself is destroyed when Rainbow pulling off a Sonic Rainboom causes it to become corrupted.
- Doppelgänger Gets Same Sentiment: Celestia still feels awful when APP is seemingly derezzed, despite the real Applejack being safe in the real Equestria.
- The Dragon: Shy, albeit a very sympathetic and reluctant one.
- Expy: Because no characters from Tron Legacy actually appear, most of the fics' cast is comprised of expies or original characters.
