"Ma Meilleure Ennemie" ("My Best Enemy") is a duet by Belgian rapper/singer Stromae and French chanteuse Pomme. Released on November 23, 2024, the song was crafted specifically for the second season of Netflix's animated series Arcane: League of Legends.

The title riffs on the French phrase "ma meilleure amie" ("my best friend"), substituting "amie" with "ennemie" to capture the peculiar affection and antagonism that coexist in certain relationships. Think of it as a musical embodiment of the phrase, "Can't live with them, can't live without them."

Arcane: League of Legends premiered on Netflix in 2021, and it quickly became one of the platform's standout animated hits. Based on the widely adored League of Legends video game, the series delves into the lives of sisters Vi and Powder as they navigate the turbulent divide between the gleaming utopia of Piltover and its gritty, chaotic counterpart, Zaun. This song appears in season 2, episode 7 as the haunting backdrop to a charged scene where Powder (known in later lore as Jinx) dances with and kisses her childhood friend, Ekko. Powder and Ekko represent two sides of the same fractured world, much like Piltover and Zaun: the utopian city and its grimy, rebellious underbelly, around which Arcane's story revolves.
