I’m not able to verify a single “who won all badge wars in Roblox” result from the information available here. The most relevant hit I found points to Badge War winners throughout the seasons with names like Yooyeon and Seoyeon, but it does not show an all-time, complete winner list for Roblox Badge Wars.

What I could confirm

  • A result titled “Badge War winners throughout the seasons” lists:
    • Season 1: Yooyeon
    • Season 2: Seoyeon
    • Season 3: Seoyeon
  • Other results were for different Roblox games such as Ability Wars and Slap Battles , so they do not answer the same question.

Most likely interpretation

If you meant the winners of the “Badge War” seasons , then the visible result suggests Yooyeon won Season 1, and Seoyeon won Seasons 2 and 3. If you meant a different Roblox game or event with “badge wars” in the title, the available result set does not identify a complete winner list.

Source note

The available search result is a short social post and not a full official recap, so it may be incomplete.
