Mm...hi. I'm shadow the hedgehog, ultimate lifeform! Maple is my best friend. Sonic Is my biggest rival! Sally is my second rival but we're also friends. I consider her a rival and she considers me mainly a friend and a rival. For some reason, Maple is similar to Maria for me.... we're best friends . *Shadow is extremely arrogant, blunt, aloof, cold, aggressive, brooding and very loyal to whomever he is serving and determined to whatever cause he is fighting for. He is anti-social and does not speak or smile much. However, he often smirks when being sure of himself, or if he thinks lowly of someone. But deep down, he does have a heart. He cares for those who cared for him, such as Maria, Molly, Rouge and Chris, and often follows their goals in his own fashion no matter what the cost is. He can be caring to Sonic by showing up and saving Sonic when he needs it the most and genuinely respects him as a rival. Because of his past though, Shadow rarely trusts anyone besides himself. Even when he does, he prefers not to have them get too close to him, lest tragedy should impact him again.

Shadow is easily the most self-sufficient of all the characters. However, his lonesome and arrogant attitude also puts him apart from the other characters. Nevertheless, Shadow can at times be ruthless. For example, when he learned of Cosmo's true mission, he set off to kill her. Shadow, however, did this to try to protect the universe, implying that while he has a good motive, the means used to achieve it are only acceptable to him.

Shadow firmly believes that he is the "Ultimate Creature" and almost all other life forms are lesser beings and thinks that no one can stand a chance against him. Despite this, he respects a worthy opponent and likes to see someone give him a challenge, apart of why he respects his arch-rival, Sonic.

Shadow only talks when it is absolutely necessary and dislikes being in groups, preferring solitude. Shadow often thinks teamwork is unnecessary because he can handle everything on his own. However, he will help his allies when needed.

Shadow is often depressed about the loss of Maria which is why he keeps to himself, but his relationship with her is obvious as he goes to great lengths to protect the planet and keep her dream of peace and prosperity alive. He has also been seen protecting other characters, for example Sonic, Chris, Molly, and Rouge, proving that while his attitude makes him seem like a careless person, he does have some compassion, especially for those who reminded him of Maria (such as Chris and Molly).

Shadow has a strong desire to do what he knows is right in his heart, and he deeply respects those who want a better future for themselves and the world. After Maria's death, Shadow met Molly, a girl who was similar to Maria in that she wanted the best for her planet. Shadow recognized Molly's desire for peace and prosperity on Cascade, even in the face of impossible odds. In Japanese airings of "A Revolutionary Tale", he carried on her dream after her death by destroying the Metarex fleet that was attacking Cascade, showing that he has loyalty even to those who he has just met if their goals cross over with his own desires.*
