Vulpinroid is a Sonic the Hedgehog Alternate Universe fan series by Cy-Fox. Set as an Alternate Universe 20 Minutes into the Future starting in the late 21st century, it features Miles "Tails" Prower as a British space naval officer and starts the series at the beginning of his career at age 15. Serving as an information warfare officer aboard the destroyer HMSS Campbeltown, he finds his feet and overcomes self-confidence issues (brought about by family problems and Impostor Syndrome), ultimately marrying his childhood friend Surgeon Lieutenant Maria Robotnik and fathering twins with her. During a surprise attack that threatens a key space station, he sacrifices himself in a suicide attack against a core enemy ship. But despite being physically killed, the young fox is still alive as an artificial intelligence. Joined to a new body, he sets out to confront the enemy and protect his family and his homelands.
The series consists of:
- Vulpinroid 1.0
- Vulpinroid: Tomorrow Is Yesterday
- Vulpinroid: Quarantine
- Vulpinroid Memento Mori
- Brits with Battleships: Tails and the whole Royal Space Navy.
- Casting Gag: Tom Holland for Lieutenant Prower, Patrick Stewart for his elderly iteration from Memento Mori. Ironically before the second Sonic movie was fully announced, Cy-Fox framed Holland as the voiceclaim for the young vulpine.
- The Captain: Lieutenant Commander Keann Zincks of HMSS Campbeltown, Lieutenant/Commander/Captain Miles Prower of the HMSS Campbeltown, HMSS Belfast and HMSS Warspite
- Colonel Badass: Amadeus Prower starts as this, then upgrades to Four-Star Badass.
- Cool Starship: HMSS Campbeltown, named for a World War II era Lend Lease destroyer that took part in Operation Chariot aptly named for what her 22nd century counterpart's final fate is. HMSS/HMTS Belfast, also named for a World War II era Royal Navy ship, Tails' first true command and finally HMSS/HMTS Warspite, named for the battleship that saw two World Wars and carried the most battle honours.
- Love Interest: Tails and Maria Robotnik
- Mind Uploading: How Tails survived ramming the Campbeltown into the Egg Carrier
- Names to Trust Immediately:Admiral Lord Miles Prower and Surgeon Vice Admiral Maria Robotnik-Prower, Earl and Countess of Devon respectively.
- Playful Hacker: Tails' first four years of naval service as information warfare officer makes him this.
- Powered Armor: Vulpinroid 1.0 outfits Tails with powered armor.
- Sergeant Rock: Colour Sergeant (later Lieutenant) Whisper who started off in 40 Commando at the age of 15 and then later got into the Vanguard Strike Company before taking a turn instructing at Lympstone putting Tails and Maria (separately) through the Royal Marines Endurance Course (six miles of hell in the moorlands crawling through small tunnels, slogging through mud and having to shoot accurately with a pistol at the end). Later ends up part of Tails' security detail as his minder when he gains admiralty. Sometimes feels redundant because her principle is a literal walking killing machine. Has a fouler mouth than Gordon Ramsay when she's talking.
- Time Police: The British Temporal Security Service as well as the United Nations Temporal Command
