Regardless of the game, Aatrox reigns supreme as the most powerful champion in Riot's arsenal.
In recent years, Riot Games has been actively integrating its characters into as many games as possible. Remarkably, Aatrox currently stands as the most imbalanced champion across all Riot titles in which he appears.
In League of Legends (LoL), Aatrox has been a powerhouse since season 12. Heading into the Preseason 2023, the Darkin Blade became even stronger with the introduction of the Jak'Sho Adaptive Armor and the revamped item - Riven's Cleaver. Consequently, Aatrox ranks among the strongest top lane champions with incredibly high pick and win rates.

Transitioning to League of Legends: Wild Rift, Aatrox doesn't exhibit the same dominance as his PC counterpart. This is understandable considering the mobile version of LoL lacks the Jak'Sho Adaptive Armor. Nevertheless, Aatrox remains a formidable top lane champion and is classified as S+ tier by Wildriftfire, a platform specializing in tier lists.

Finally, in the card game Legends of Runeterra, Aatrox also stands out as the most imbalanced champion. Decks centered around Aatrox have the ability to control matches and decisively defeat opponents. Consequently, the top-ranked players across the Americas, Europe, and Asia all utilize the Aatrox - Vayne deck.

Fortunately, Aatrox is absent from Teamfight Tactics season 8. Otherwise, he might have been the strongest champion in this autobattler genre. Hopefully, Riot Games will make appropriate adjustments to curb Aatrox's dominance in this game mode.
