Ever since former Overwatch director, Jeff Kaplan, confirmed that the studio had "big plans" for the Junker Queen, fans have been waiting for the hero to come to the popular hero-based shooter at some point. Although Junker Queen probably won't ever be coming to Overwatch now that it's on its way out, it appears that the highly anticipated hero is coming to the sequel, as per the latest leaks.
According to former Overwatch League coach Félix 'Féfé' Münch, a viewer sent him details of what could just be the abilities and ultimate of Junker Queen. In addition, Junker Queen's sword will have a boomerang function where she can throw it at enemies and call it back, possibly hitting anyone in the way as the weapon flies back to her. The leak also suggests that the Junker Queen will have an ability where allies will gain 100HP alongside a 200 HP boost to herself, Rallying Call. The same ability will also apply a movement buff to Junker Queen, but it's not yet clear if it will also apply to her teammates.
As for Junker Queen's other abilities, Carnage will deal AoE damage to all enemies in front of her and apply a bleeding effect while her passive, Adrenaline Shot, will work similarly to existing abilities like Widowmaker's Venom Mine or Ashe's Dynamite.
Finally, the Junker Queen's ultimate, Rampage, will see her charge in front of her enemies and deal anti-healing effect while applying a heal to herself.
