Ravio has been revealed for the upcoming Hyrule Warriors (Legends) DLC pack. This last pack, themed after Zelda: A Link Between Worlds, was originally scheduled for winter. In an interesting twist, it looks like we will be seeing it in a week!
Next to Ravio, we will be seeing another character from the Nintendo 3DS title. (This was previously leaked, but we are keeping under wraps here.) There are also 15 My Fairy Costumes, one map for Adventure Mode (with one adventure battle and two challenge battles) and 17 costumes.
