Tails

Tails is the titular main character of Tails and Sonic Pals and often appears on the channels GottaGoGast! and Emerald Masters alongside his friends Sonic and Knuckles respectively. He is voiced by BulmaBunny.

Personality
Tails is a young and energetic twin-tailed fox engineer. He is incredibly smart and willing to help his friends and support, usually without asking questions. Though he can be easily frightened, he tries his best to be strong and face his problems, and whenever he can he will always seek to resolve problems.

Contrary to most of his official/canonical counterparts, however, Tails is quite cunning and sneaky. He seems to enjoy making his friends look at fanart of themselves, usually at their expense and for his own enjoyment. An example of this would be when he forced Sonic and Shadow to look at the artwork of the Sonadow ship on DeviantArt. As a result, a lot of his friends have become untrustworthy of him and cautious that he might make them do something embrassing. Furthermore, Tails seems to have no problem wth 'playing the field' when it comes to love interests and is willing to be romantically involved with multiple characters at a time - though usually without them knowing. This has led to his other friends calling him out for it which he usually denies.

An additional contrast to his canon counterpart is that Tails has on occassion shown signs of dopiness or lack of intelligence, although this may simply be down to mistakes on the part of his voice actor.

Appearance
Tails is almost identical to how he is typically depicted in the Modern Sonic canon. He is an orange fox with patches of white fur, two tails and blue eyes. He wears red and white shoes and white gloves. Unlike his Modern design, his ears are slightly smaller and more upright, more like how they are in Sonic Boom. His three bangs of hair at the front also appear to be proportionally shorter than in most official depictions of the character.

Sonic the Hedgehog
Sonic and Tails, much like the official counterparts, are long time best friends and are inseperable to the point of being brothers. Though there has been friction between the two in the past, usually over Tails' insistence to try and force Sonic into a relationship with Amy and his DeviantArt videos, there is no love lost between them.

Amy Rose
Amy is one of Tails' closest friends. Like Sonic, there have been tense moments between them in regards to his DeviantArt videos, but at the end of the day they get along like a brother and sister.

Cream the Rabbit
Cream's relationship with Tais has been very rocky and inconcistent. While they at first got along and she was considered one of his love interests, after Shadow called out Tails' multiple love interests in front of Cream, she decided that she didn't want to be involved with him anymore. Regardless, the two remain friends but are now a one-sided relationship, much to Tails annoyance.

Shadow the Hedgehog
Tails and Shadow used to be on unequal terms but have since gained a relationship akin to friends. That being said, Shadow is usually the most put-off and annoyed by Tails' cunning antics, even going so far as on one occassion to lash out at him with Chaos Control.

Millie "Tailsko" Prower
Tailsko is the genderbent version of himself. As a result, the two are seemingly identical in nature and get along very well. It has been implied that they have a crush on each other, but neither of them are willing to take the first step knowing that they are the same person.

Trivia

 * According to Tails himself, the reason he has changed from his 'usual nice self' is because he has been corrupted by YouTube and it's algorithm, saying "Money's nice."
 * In a deleted video from the channel where Coco Bandicoot appeared, Tails in the description described Coco as a friend of his from another dimension. However, the character has yet to appear again on the channel in any capacity, so it is unclear whether this remains the case.
 * It has been implied that Tails may also have a crush on his plane, the Tornado, althought this may simply be a reference to the cargo ship between them.
