The Super Hero Girls and the Sonic Boom

At high school, a group of six teenage girls became super heronies and ended up meeting five anthropomorphic creatures on an island called "Seaside Island", or "Bygone Island".
Enter the Super Hero Girls and Team Sonic, who are ready to save Metropolis and Bygone Island from the clutches of the Super Villian Girls, Dr Eggman and many more foes.
Eleven friends, six heroines, five anthropomorphic animals, two teams, one whole friendship.
Join Sonic the Hedgehog, his friends and the Super Hero Girls to stop bad guys from wreaking Metropolis and defeating Eggman's robots.

WOULD YA LOOK AT THAT, MY FIRST DCSHG FIC! Anyway, the Sonic Boom characters are gonna replace the Teen Titans as the final parts for Harleen/Harley to be reformed is "Eggman: The Video Game" Part 1 and 2.
