Dark Super Tails fanfiction often takes the normally positive and heroic character of Tails from the Sonic universe and gives him a darker, more complex twist. It might involve him being corrupted by some dark power, or having a different set of motives that go against his usual good - natured self. Writers may explore how his friends in the Sonic world would react to this new, darker Tails.
One common plot is the corruption arc. Tails gets exposed to a dark power source, like an ancient, evil artifact. This power slowly changes his personality and goals. For example, he might start to see Sonic as a rival to be defeated rather than a friend.
A lot of Dark Sonic and Tails fanfictions also focus on the relationship dynamics. The contrast between Dark Sonic's aggressive nature and Tails' more timid and rational self creates a lot of tension. Sometimes, the fanfictions might show Tails growing stronger in the face of Dark Sonic, evolving from just a sidekick to a more independent character who can stand up to this new threat.
One common theme is the corruption of Tails' innocence. Since he's usually seen as a sweet and intelligent character, seeing him corrupted by dark forces makes for an interesting story. Another theme is isolation. Tails might be isolated due to his new dark nature, which can lead to his further descent into darkness. And revenge is also a theme sometimes, where Tails might seek revenge against those who he believes have wronged him in his new, darker state.
One interesting plot could be the exploration of a new, hidden power that the main character in the fanfiction discovers. This power might change the dynamics of the story and lead to new adventures.
It depends on how the fanfiction is written. But generally, Dark Sonic has superhuman speed and strength. However, Tails is very intelligent and resourceful. If Tails has enough time to prepare, he might be able to win. But if it's a sudden encounter, Dark Sonic would likely overpower Tails.
