Sonic the Hedgehog 5 (1997)

Sonic the Hedgehog 5 is an American platforming action adventure video game based on the original Sonic IP by SEGA, and will serve as a sequel to both Sonic the Hedgehog 3 (1994), and Sonic & Knuckles (1994). It was developed by SEGA Technical Institute and published by SEGA for the Sega Mega Drive, Sega Genesis, and PC. It was released during the second quarter of 1997 on April 22nd, 1997. 
The game picks up after the events of Sonic the Hedgehog 3 (1994), Sonic & Knuckles (1994), and Sonic Adventure (1998), and sees our blue-blurred hero on another adventure to stop the evil Doctor Robotnik on his mad quest from calming the Chaos Emeralds for his own. The game tells the story of Knuckles joining Sonic's crew, and also going on his own adventures to protect the Master Emerald, save Angel Island from any possible future attacks by Doctor Robotnik, and also stopping Robotnik from using the Chaos Emeralds to power his latest device The Egg-Scrambler from eradicating the world of hedgehog kind. This time though, it won't be easy for any Hedgehog, Echidna, or Fox to plow through, as Robotnik will now be tricking a bounty hunter named Fang the Sniper into believing that Team Sonic was going after his prized possessions. Fang joined their team after realizing that Robotnik was only simply using the bounty hunter for his large pile of gold. 
Like Sonic the Hegdehog 3, Sonic the Hedgehog 5 had a second part titled Sonic the Hedgehog: Save the World (1998) that featured Fang the Sniper recruiting his old team members Bean the Dynamite, and Bark the Polar Bear to stop Robotnik from obtaining his large pile of gold for his own personal goals. The second part was released on February 6th, 1998.
