Brawlhalla

Fewer than 10 collectors on BadgeBase carry this one, which puts Brawlhalla firmly in rarity territory. It is a global Twitch badge tied to the free-to-play platform fighter of the same name, dating back to an era when Twitch linked badges directly to individual games.

How was it earned? No official window or unlock method survives in the records, which is typical for these early game badges. Years later the community did get another Brawlhalla design: BrawlhallAwoo arrived as a paid badge for subs.

If barely-seen designs are your thing, the rare badges page ranks the scarcest icons across all of Twitch.
