Shadow.

Shadow is a dark hedgehog with scarlet stripes on his needles. His eyes are scarlet (Sonic's are emerald). This hedgehog is: angry, cold, serious, gets irritated because of the annoying Sonic; always crosses his arms over his chest in any situation, rolls his eyes and can show the finger whenever he wants. He is also jealous of Sonic for many of his friends (girls), especially this Amy, who always sticks to him. Shadow also has super speed, like Sonic, but he is twice as fast and stronger than the blue hedgehog. Also, he always calls Sonic not by name, but for example: Blue spot, fake. Even if Shadow has a loving relationship with someone, he will still be just as rude in them, but just a little bit, maybe soft. He is also proud that he is brave, you can rely on him and he is the highest form of life. By the way, his super speed is in his air boots. He keeps to himself and doesn't tell anyone anything about himself. He can hit hard or push away someone who really irritates him. There are often fights between him and Sonic, because Sonic is hitting on him or pestering him. Shadow hates parties, so he only agrees to them if they are hosted by his friends - either Blaze or Rouge. He trusts them both and is more open to them than to anyone else. He also always has his gun with him. Shadow can really hurt anyone he talks to with his words; tease him/her, swear a lot.
