A Regular show fanfic by Cherripepsi :)
When a shadow from another world arrives in the park, Rigby finds himself drawn into a dangerous game with a version of Mordecai unlike any he’s ever known. As chaos spreads and reality bends, the line between friend and foe blurs, and Rigby must navigate power, manipulation, and his own impulses. Dark, surreal, and twisted, this story explores what happens when the familiar becomes terrifyingly unfamiliar—and how far loyalty can stretch in a world gone mad.
