''[[http://www.fanfiction.net/s/5349797/1/ Training Tails]]'' is a Sonic the Hedgehog fanfic by Stainless Steel Fox, set in the [[WesternAnimation/SonicSatAM SatAM]] continuity. As the name indicates, the fic focuses on Miles 'Tails' Prower and his personal journey to train himself to become a more valuable member of the Freedom Fighters.

How does he do this? After an attempt to take down Robotnik's latest plan all by himself goes awry, Tails ends up getting inadvertently transported into the DragonBall universe by an interdimensional portal. There, he meets up with Goku, and together they undergo a crapload lot of TrainingFromHell. The two-tailed fox ends up taking [[TookALevelInBadAss several levels in badass]] and becomes significantly more powerful and intelligent. As his adventure goes on from there, however, he realizes he has much more to learn beyond just kicking ass and taking names.

The first part of the fic is a crossover with the manga version of DragonBall, while later stages will be a crossover with the VideoGame/StarFox universe.


!!Tropes included in ''Training Tails'' include:
* AwesomenessByAnalysis: One of the most defining traits of this depiction of Tails, such as being able to calculate trajectories on the fly before deciding on how to throw objects.
* BadassBookworm: Tails, very much so after his training under Master Roshi.
* ColdBloodedTorture: In Chapter 23, during a fight with Tien Shin Han, Tails gets overwhelmed, and ends up [[spoiler: getting his tails forcibly ''ripped off'' his butt. Only by taking a magical Senzu Bean given to him by Goku earlier is he able to regenerate them instantly and get back up.]]
* {{Crossover}}
* CurbStompBattle: Most of the Red Ribbon Army stand pretty much zero chance against Tails or Goku in a fight, though it does get gradually harder for the duo.
* GogglesDoSomethingUnusual: Tails' goggles are one of the most useful gadgets he has, having a whole host of features such as nightvision, blocking out the moon (for the pair given to Goku to prevent his transformation into a Great Ape), detecting enemies, detecting dragon balls, etc.
* HardWorkMontage: While building the Sea Fox, set to the ''Series/MacGyver'' theme song no less.
* HowWeGotHere: The second chapter already shows Tails returning to Mobius after completing his training, and the entire fic from there shows everything he had gone through and experienced within six years.
* IdiotHero: Goku, much like in the canon.
* TailSlap: The Tailspin attack is an UpToEleven version of this.
* TrainingMontage: Chapter 5.
* {{Technobabble}}: Tails being a technical genius and the author being a big sci-fi fan and actual engineer by profession, this comes from the fox a lot.
* ThouShaltNotKill: Tails tries to hold onto this principle as hard as he can, but comes to realize it's really not that easy in the DragonBall world after encountering the Red Ribbon Army. [[spoiler: Notably, it actually led to Tien getting an advantage over him in the fight mentioned above, as Tails did not use lethal force when he could have.]]
* YearInsideHourOutside: Six years pass for Tails while only an hour passes for the rest of the Freedom Fighters on Mobius.
