Shadow the Hedgehog

Shadow the Hedgehog (シャドウ・ザ・ヘッジホッグ Shadō za Hejjihoggu?) is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic hedgehog/Black Arm hybrid and the arch-rival of Sonic. Shadow was created by Dr. Gerald Robotnik, using the DNA of Black Doom, and is the end result of Project Shadow.

Why He Rocks

 * 1) His entire backstory is very tragic and sympathetic while trying to destroy humanity for the loss of his best friend Maria. But in a change of heart promised her to protect Earth.
 * 2) A brooding loner by nature, Shadow constantly refers to himself as "The Ultimate Lifeform" as he is egotistical, serious and self-absorbed, yet calm and anti-heroic by the most part.
 * 3) His personality and abilities make him a good archrival for Sonic.
 * 4) Regardless of his motivations, he has helped Sonic the Hedgehog and his allies save the world multiple times.
 * 5) Shadow has lots of amazing music in Sonic Adventure 2 and Shadow the Hedgehog, called "Throw It All Away", "I Am...All of Me", "All Hail Shadow" and "Never Turn Back".
 * 6) While a loner, Shadow still has people he loves and cares for, mainly his teammates Rouge the Bat and E-123 "Omega".

Bad Qualities

 * 1) His self-titled game received a very bad reception, but it was a huge success.
 * 2) His popularity sometimes overshadows other Sonic characters, such as Tails and/or Knuckles.
 * 3) In recent years he has become more edgy, but not as bad as his Sonic Boom counterpart.

Trivia

 * 1) The look and feel of his character was based on movies like Underworld, Constantine and the Terminator films.
