Wolfie is a character that appears in the Sonic Boom television series. He is an anthropomorphic wolf and Wolfie's counterpart from an alternate dimension where Sonic never existed. He is also a member of the Rebellion.
Wolfie is essentially a doppelganger of his Sonic Boom World counterpart and is so identical to him in both anatomy and attire.
At some point, Wolfie joined the Rebellion, a resistance group that opposed Lord Eggman's rule over Seaside Island.
When scrolling through the Village Center, Wolfie backed off when Lord Eggman passed by. He later joined the Rebellion at their camp while Amy showed Sonic around.
Like many other locals, Wolfie is shown to fear Lord Eggman greatly.
