At the International 7, Valve revealed two new heroes for DOTA 2: a pink fairy and an anthropomorphic armadillo-like swordsman. While these heroes have been present in game files since May according to Redditor DoctorGester, their visual reveal at the International 7 makes their presence known to the DOTA 2 community.
The two heroes appear to be a rapier wielding hero and a fairy who was previous leaked on Reddit. Although their names and their abilities are unknown, these two heroes will be coming out in the Dueling Fates patch. The last time a hero was released in DOTA 2 was December 2016, when the Monkey King made his debut in the game.
