Summary:
Sonic was created in 1991 hoping to be more popular then Mario and take Nintendo out of the system race and to get a new mascot from Alex Kidd. His first appearance was in the game "Sonic the Hedgehog" on the "Genesis", also known as the Mega Drive. It was a success, with the game following on with "Sonic the Hedgehog "2" and "Sonic the Hedgehog 3".

Overall:
He is a great video game character with some good superpowers. However, the main reason he was created was because SEGA wanted to get Nintendo out of the system race. So that was why I rated Sonic 4.5/5 Stars.
