Background
Shadow the Hedgehog is a character from the series Super Mario Bros. Super. Shadow was genetically created by Dr. Gerald Robotnik on the Space Colony Ark to help cure his daughter Maria, who was terminally ill. On his time on the ark, Shadow and Maria became very close. Unfortunately, the government invaded the Space Colony Ark since they thought Shadow would be a threat to the world. He was captured by the government and Maria was killed right in front of him.

50 years later, Shadow was freed by Dr. Eggman. Shadow was angry for what the government did to Maria, and he planned on killing the people of Earth. However, after meeting Sonic and remembering what Maria's last words were before he died, Shadow decided to help save the Earth and protect the people, fulfilling his dead friend's final wish. Shadow now is an ally of Sonic and his friends, helping them face off against Dr. Eggman and his army.

In that timespan afterwards, Shadow and their friends had met up with another group of heroes from another multiverse. The leader of these heroes was Mario, the main hero of the Mushroom Kingdom.

Personality
Shadow, like Vegeta was, is a loner. He is very serious, unlike most of his allies. He is rarely seen with anyone, except Vegeta, for an extended period of time, and he distances himself from most people.

Shadow is extremely cocky, and considers himself the Ultimate Lifeform. Like Sonic and Vegeta, he can be extremely arrogant, often underestimating his opponents. He is more like the latter in that he often belittles his opponents if they are weak. He believes that few can challenge him, and he thinks of most as a fool for doing so, with Vegeta, Goku, and Sonic being notable exceptions. Shadow is a lot more serious in combat, and like Vegeta, he is not very forgiving towards his enemies and sometimes others need to convince him to forgive them, unless there is a clear reason for him to trust that enemy.

Shadow is also very stubborn and smug, like Vegeta was in the past. He often speaks his mind, whether the people around him like it or not. This has sometimes created tension with some characters, like Sonic or Knuckles.

Shadow, like Vegeta, can be violent and short-tempered. Almost none of his enemies take him lightly, as they know how violent he can be. Shadow is shown to be even more violent, aggressive, and brave than Vegeta, to the point where he fears almost nobody unless they outclass him in power. Shadow can be so aggressive and violent when angered that  even Amy Rose, Bulma, and Chi-Chi are shown to fear him whenever he gets angry. He has no fear of them, unlike almost everyone (even Vegeta fears Bulma's temper, albeit to a far lesser extent than the rest of the Z-Fighters, Sonic, and Tails), and their outbursts can sometimes set him off

Shadow's arrogance can occasionally cause him to brush off any kindness or sympathy given to him. Sometimes, though, he can appreciate people caring for him.

Despite his attitude, Shadow is somewhat compassionate, and has shown concern for his allies.

Expert Hand-to-Hand Combatant
Shadow is master at the art of physical damage with his bare hands, having his fighting style, depicted as brutal and quick, with swift punches, karate chops, and roundhouse kicks as part of his arsenal.

Skilled Biker
Shadow is a skilled motorcycle/bike user and can drive better than many people. He's also able to do many stunts like jumping with it or spinning as well.

Homing Attack
Although not used often, Shadow has a homing attack just like Sonic and works just as efficiently.

Minor Super Strength
Shadow has shown great strength, being able to lift heavy concrete plates and to break solid metal with strong attacks.

Super Speed
Shadow is one of the fastest characters of all franchises, being able to par with Sonic. His max normal speed is the speed of light, and he can surpass it if he transforms.

Gigantic Resistance
Shadow is very resistant to damage, shown in feats such as surviving from a fall from space to Earth, being shot multiple times, being struck by a gigantic robot, and many other things. Shadow can hold his own with most enemies and is as durable as Sonic is.

Proficient Gunman
Shadow is very proficient in using guns, being able to effectively aim and shoot at insane speeds. He's also able to use different varieties like machine guns and handguns.

Skilled Swordsman
Shadow is apt to use swords and katanas as weapons since he managed to defeat many G.U.N. agents, Eggman robots, and Black Arms aliens using swords. He's able to go head-to-head with Sonic although with the latter winning Shadow still showed prowess.

Chaos Manipulation
Shadow's trademark ability. He can use Chaos in various ways, such as in energy bursts, time-stopping, teleporting, defending, increasing his stats, and many other ways. This power can be upgraded if Shadow removes his Inhibitor Rings, which increases his power so great that he could destroy an entire army of perfect clones of a time demon; However, his stamina depletes much faster than normal.

Gravity Manipulation
Shown in Sonic Free Riders, Shadow can control gravity to dive and to make maneuvers in his Extreme Gear.

Space-Time Manipulation
Shadow can alter space-time, allowing him to stop the time, teleport, distort it and to create dimensional/chaotic rifts. He's also able to move freely while everything is motionless for a brief period giving him the advantage of time.
