All Catch a Brainrot Brainrots (Brain Index)

The Brain Index is Catch a Brainrot's living dex, and it currently tags 36 Brainrots as of launch week on 2026-07-13, three days after the 2026-07-10 release. That count already tops the strongest competitor tracker, bloxinformer, which indexes 29. Every entry is sorted by rarity across four tiers: 7 Epic (Chicleteira Bicicleteira, Spijuniro Golubiro, and more), 11 Rare, 9 Uncommon, and 4 Common. Rarity is not cosmetic flavor here; it is the game's real classification, signaled in the wild by a colored glow, and it decides how much a capture is worth in Index XP and Tong Coins. Use the filter above to narrow by tier, then tap any card for its full entry. More Brainrots register here as the community confirms them during launch week.

Rarity glow explained

Every wild Brainrot broadcasts its rarity through a glow you can read before the battle starts, so you decide whether to spend a Capture Box the moment it appears on screen in World One. Common Brainrots such as Flamingulli, Tric Trac Barabum, Penguino Cocosino, and Quivioli Ameleonni carry no glow at all. Uncommon Brainrots pulse green, covering the nine names in that tier including Tralalero Tralala, Glorbo Fruttodrillo, and Six Seven. Rare Brainrots pulse blue, a group that runs from Ballerina Cappuccina and Tung Tung Tung Sahur to Cappuccino Assassino across all 11 entries. Epic is the top tier, holding the seven rarest catches like Lirili Larila, Bombombini Gussini, and Strawberrelli Flamingelli.

Rarity also gates which Capture Box you need. The early Wooden Box handles Commons, the Golden Box Level 9 reaches Uncommon, Level 15 covers Rare, and Level 22 is built for Epic. There is no type or element system in Catch a Brainrot, and no per-creature battle stats are published, so glow color and HP are the only signals you act on. A higher-rarity catch also sells for roughly 5x its defeat value, feeding faster into upgraded golden boxes. See the starter guide to pick a party that survives long enough to weaken these tougher pulses.

How the roster grows during launch week

The 36 figure is a launch-week snapshot, not a final ceiling. Catch a Brainrot released on 2026-07-10 after slipping about two weeks from its original June 26 target, and community trackers list new Brainrots as players confirm them across World One and the two reported additional zones, a Grass Zone and an Ice Zone, both at medium confidence during launch week. The live experience was drawing roughly 9,790 concurrent players against 1,446,272 visits and 10,901 favorites on 2026-07-13, so confirmations arrive quickly as thousands sweep each zone.

New entries register in one specific way: you throw a Capture Box at a weakened wild Brainrot, catch it while its HP is low, and it books into your Brain Index for Index XP that unlocks better shop boxes. Every first-time catch expands both your personal count and the shared roster picture. Developer Indieun announces genuine additions through the official Discord at discord.gg/indieun and @Indieun on X, which is also where any future codes would appear; none exist yet as of 2026-07-13. When more Brainrots are verified, they slot into this Index by their rarity tier and glow, so the four-tier sort above stays accurate as the total climbs past 36. Browse the full grid at /brainrots/.
