Shadow

Shadow is a recurring character on the Tails and Sonic Pals channel. He is voiced by Emerald Masters where he is one of main characters alongside Knuckles.

Personality
Shadow is incredibly serious, and often considered by many as almost always grumpy. His sense of independence, complete fearlessness and belief in himself as "the ultimate lifeform" has given him a bloated ego, though he usually only ever flaunts it around Sonic. He is easily angered by nearly everyone, especially when they manage to get under his skin.

This is not to say that Shadow is completely unfriendly or heartless, as he has shown signs of occasional friendliness to others - usually if it's to the detriment of someone he's not friends with or finding a bother. He has also demonstrated himself a parental figure, though whether he could be considered a good influence is questionable.

Miles "Tails" Prower
Although Shadow says that he is Tails' friend, this is largely up for debate as he more often then not can be annoyed by the fox, usually in regards to DeviantArt videos. Similarly, Tails is usually more scared of Shadow than not, though he's not afraid to ruffle his feathers from time to time.

Sonic the Hedgehog
Shadow's relationship with Sonic is almost identical to how it is depicted in official canon. Fierce rivals, they often get into arguments about who is better and don't agree on a lot of things.

Knuckles the Echidna
Knuckles and Shadow share guarding duties for the Master Emerald, with Shadow taking over the role whenever Knuckles isn't available. This in turn gives the pair a mutual friendship, though it is normally never seen or made aware as they rarely appear together. With the exception of Cream the Rabbit and Shadie, Knuckles is probably the person Shadow is the least annoyed by.

Amy Rose
Shadow has a certain level of tolerance for Amy, and the two are generally on friendly terms. He does find Amy's peppy nature to be annoying though, and likewise she is often displeased with Shadow's near constant grumpiness.

Cream the Rabbit
Cream is one of the few people that Shadow treats with a level of respect. Though he does find her childish behavior to be beneath him, he is always willing to act as her guardian - even at one point referring to her as his daughter. In return, Cream sees Shadow as a brother-figure and enjoys spending time with him. However, Shadow's mannerisms have rubbed off on Cream somewhat, raising questions about whether he is a bad influence on her or not.

Rouge the Bat
Despite being team members on Team Dark, Shadow's relationship with Rouge is exclusively work centric. Though he finds her to be not as much of a problem as other characters, as a part-time guardian of the Master Emerald he is bothered by her attempts to steal it. He also finds her attempts to flatter him annoying, as they are usually ploys to make him do whatever she wants - more times than not unsuccessfully.

Shadie the Hedgehog
Shadie is the genderbent version of himself. As a result, the two are seemingly identical in nature and get along very well.

Trivia

 * For Valentines Day 2021, Shadow made a video on the Emerald Masters channel where he googled himself with his bike. While this could be interpreted as Shadow having a crush on it, it is more likely his way of saying that he has no interest in romance.
 * According to a question asked during a livestream, Shadow's perfect gun is a rocket launcher-machine gun hybrid.
 * Though nothing exists in the real world, a gun matching that description exists in the Ratchet & Clank series in the form of the R.Y.N.O. series of weapons, more specifically the R.Y.N.O. II from Going Commando. It is so far unclear whether Shadow knows of this weapon's existence or not.
