In 2018, Blizzard Entertainment's game director Aaron Keller described D.Va's programming as complex, leading to amusing bugs during her mech transitions. D.Mon is a new character in the MEKA Squad, designed for sturdiness and versatility, capable of dashing in any direction with limited fuel and equipped with a mounted machine gun. When she raises her shield, she resembles Reinhardt but has a speed advantage and a unique charge ability. D.Mon's ultimate ability, Limit Break, unleashes a whirlwind slash that increases enemy damage taken and grants her overhealth. A notable gameplay moment occurs when she is ejected from her mech, with an animation reminiscent of Voltron. D.Mon will debut in season 4 on August 11.
