Sonic the Hedgehog

Sonic the Hedgehog is a playable minifigure in LEGO Dimensions. He appears in Year 2 of LEGO Dimensions.

Background
Sonic the Hedgehog is a 15-year-old anthropomorphic blue hedgehog and the fastest thing alive. He has constantly gone through islands such as South Island, Westside Island, and Angel Island to save them from the mad scientist, Doctor Eggman. He would later find himself fighting nearly god-like beings known as Chaos, Dark Gaia, the Time Eater, and the Deadly Six. He is the leader of Team Sonic which is a trio of heroes including his best friend Miles "Tails" Prower and close friend Knuckles the Echidna who frequently team up to fight against Eggman. He has many other friends including characters such as Tails, Amy Rose, Knuckles, Silver the Hedgehog, Blaze the Cat, and Cream the Rabbit. He has also formed rivalries with Metal Sonic, Shadow the Hedgehog, and Jet the Hawk. Upon collecting the 7 Chaos Emeralds, he can transform into Super Sonic.

Sonic Dimensions
Sonic was briefly seen running across the Green Hill Zone retrieving a Chaos Emerald for Tails. As soon as he arrived at Tails' Lab, he discovered that Tails, Big the Cat, Knuckles, Amy and Shadow were captured by Doctor Eggman, who also stole the other 6 Chaos Emeralds; Sonic freed his friends shortly afterwards. However, following Doctor Eggman's mistake of activating the Keystone (which led his friends--minus Tails--, Eggman himself and the other remaining Chaos Emeralds sucked into portals), Sonic then asked Tails for a plan and went to different areas in his world to claim the other Emeralds and find his other friends. After claiming all of the Emeralds and successfully defeating both Doctor Eggman and Chaos, Sonic and Tails went into a portal, to rescue Amy. This leaves their fate currently unknown.
