Marci, from Netflix's DOTA: Dragon's Blood series, was revealed to be a playable hero at The International 10, and released with the recent patch.
In DOTA: Dragon's Blood, Marci is the loyal servant of Mirana, Princess of the Moon, among the most iconic Dota 2 heroes and one of the principal characters of its animated series. As the series progressed, Marci became quite the favourite among fans of both Dota 2 and DOTA: Dragon's Blood due to her expressive and bubbly demeanour — which shines through despite her being mute — that belies her fierce loyalty and proficiency in hand-to-hand combat.
In Dota 2, Marci is a strength melee hero that can provide a damage and lifesteal buff for herself and her allies while also having great disable and mobility options. Her skillset lends itself well to being her team's carry, making her the first dedicated carry hero to join Dota 2's roster since Monkey King in late 2016.
