Each anime season has its own group of top brawlers who are renowned as the best brawlers in their worlds.
In the first season, the initial top brawlers were global Bakugan champions and the best in their respective attributes. Most of them, save for Shun, were brainwashed into becoming Masquerade's minions with Naga's Negative Energy. All of them were defeated by the Battle Brawlers to free them from Naga's control, thus losing their rankings as well.
3. Chan Lee
6. Shun Kazami
10. Billy Gilbert (10th best brawler; 7. - 9. are unknown)
The ranking at the end of the season:
- Dan Kuso
- Alice Gehabich (Masquerade, formerly)
- Shun Kazami
- Klaus von Hertzon
- Chan Lee
- Runo Misaki
- Marucho Marukura
- Julie Makimoto
- Julio Santana
- Komba O'Charlie
- Billy Gilbert
The Vexos are recognized as the top Vestal brawlers of their attributes. At the end of the first arc, its top two brawlers, Spectra and Gus, leave and their places are filled by Zenoheld and Hydron. The other members' rankings remained the same.
- Spectra Phantom (first arc) / Zenoheld (Deceased) (second arc)
- Gus Grav (first arc) / Hydron (Deceased) (second arc)
- Mylene Farrow (Presumably deceased)
- Volt Luster (Presumably deceased)
- Shadow Prove (Presumably deceased)
- Lync Volan (Presumably deceased)
The Resistance has its own ranking:
By the end of New Vestroia, all of the Vexos members have perished, with the exception of Spectra and Gus who defected. It can be assumed that Vestal's top brawlers are now Spectra (Pyrus), Gus or Mira (Subterra), Ace (Darkus), and Baron (Haos), with vacancies for Aquos and Ventus as those positions in the Resistance were held by human brawlers.
At the start of the season, Dan, Shun, and Marucho are introduced as the top three brawlers in Bakugan Interspace.
- Barodius (Deceased) - Emperor of, and the best brawler in, Gundalia, later mutated into Mag Mel in Mechtanium Surge
- Gill (Deceased)
- Airzel (Deceased)
- Kazarina (Deceased)
- Stoica (Deceased)
- Ren Krawler - Best brawler of the Gundalian Agents
- Sid Arkale (Deceased)
- Jesse Glenn
- Zenet Surrow
- Mason Brown
- Lena Isis
By the end of Gundalian Invaders, the top six members of the Twelve Orders save for Nurzak, plus Sid, are either dead or otherwise no longer in Gundalia. It can be assumed that the remnants of the Twelve Orders filled their vacancies, with an empty seat for Pyrus with both Gill and Sid who are dead.
The rankings at the beginning of the arc:
Due to Mag Mel reabsorbing Sellon and Anubias to revitalize himself, as well as the whole Interspace, the rankings does not exist anymore in the arc, therefore ignoring it for the rest of Arc 1.
