Avengers Grimm

Snow White and Prince Charming's kingdom is under attack by Rumpelstiltskin's brainwashed army of thralls. After killing the prince, Rumple confronts Snow in the throne room; he wants access to the Magic Mirror, which can act as a portal to a land without magic, where he can reign unchallenged. A fight ensues, resulting in them falling through the mirror's portal and into the other world. Later, Cinderella, Sleeping Beauty and Rapunzel arrive, noting the time that's passed since the battle, and how the other world's time moves much faster than theirs; they are joined by Red Riding Hood, who is tracking down Rumpelstiltskin's right-hand man, the Wolf. Having survived the battle, the Wolf attacks them; he tackles Red into the mirror, shattering it and embedding a shard into her shoulder. The princesses follow after them.
