My Knucklehead (Movie! Knuckles x Human! Reader)

Y/N was a teenager that lives in Green Hills together with Tom, Maddie, Ozzy, and her best friend, Sonic. She was adopted at a young age by Tom and Maddie and she's thankful to call them her parents.

When Tom and Maddie went to Hawaii, Y/N stayed at home with Ozzy and Sonic. While they're enjoying their lives, Eggman sadly came back but however, with a new partner. Knuckles was a red echidna that was after Master Emerald. When Knuckles laid his purple eyes on the human girl, he fell in love and wanted to protect her secretly from Eggman. Y/N knew from her heart that Knuckles was not a bad guy.

While Sonic and Y/N were after the Master Emerald, a cute two-tailed fox named Tails joins on their journey! Will Knuckles and Y/N be together?

(Based on the movie Sonic the Hedgehog 2)
