The Ultimate Badass
⚡ Ultimate Badass ⚡
After three epic editions in Berlin and Cologne, we are preparing Ultimate Badass 4 — bigger, louder, and more intense than ever before.
We are planning the 4th chapter of the all-women martial arts competition format for spring 2026. In the cage, women will be in the spotlight — newcomers as well as experienced fighters — showing what they can do: MMA, K1, grappling, and boxing in their raw, pure form. No show. Just real skills, determination, and fighting spirit. Because one thing is clear: the share of women in combat sports is growing, but they are still underrepresented. We are changing that. Ultimate Badass is our stage for everyone shaping the future of women's combat sports.

"At "The Ultimate Badass" by chinkilla, everything felt different: relentless effort to find opponents, flexible weight classes, and opportunities for everyone—from beginners to advanced fighters—regardless of their follower count.
What made "The Ultimate Badass" so special to me was that, in most cases, competitions look like this for me: few to no opponents, yet high participation fees, mismatched and rigid weight classes, little media support, few opportunities for superfights due to lack of experience, not enough followers, no girls in my weight class, limited spots for FLINTA* competitors, and much more."
