Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Naga Siren wins the Mars vs Naga Siren matchup: Naga Siren beats Mars in 53.22% of 1,071 ranked matches.
Fighting inside an Arena of Blood is often a death sentence, but Naga Siren has the perfect answer. She can use Song of the Siren to pause the entire engagement, allowing her team to reposition or simply walk out of the Arena, completely negating Mars's signature ultimate. This core interaction makes teamfighting incredibly difficult for Mars. Even outside of that, his game plan struggles. His single-target Spear of Mars is unreliable against a screen full of illusions, and Naga's army can easily surround him, bypassing the frontal protection from Bulwark. Mars wants to control a fight, but Naga Siren dictates its pace and positioning from start to finish.
