UFC Fighter Builder: every attribute and weight, how title shots and belts are earned, the Hall of Fame math, and the best fighters posted

The nine attributes

Frame is reach, not height. "Teams" are countries; the figure tints to the flag.

What lands

• About 300 fighters from public MMA rankings across 12 divisions plus the champions, with ratings derived from style and record, plus 12 retired icons (Silva, GSP, Liddell, Cormier and company; active champions are never duplicated as legends).
• 4% Legend, 5% Prime, tier-weighted otherwise. One Re-spin, one Boost, one Snag.
• No weight-class picker: the sim assigns the division most of your nine fighters came from, or a seeded one of the eight if there is no majority.

How the career works

• Start at 20. Max age ≈ 30 + 0.09 × Cardio + 0.012 × (Chin − 50), clamped 26 to 42. Cardio is longevity and fight frequency.
• Fights per year scale with Cardio, capped at two once you are champion.
• Title shot: be ranked top 3 on a 3-fight win streak. The roll is (rating − 84) / 30, between 3% and 60%, halved if you have already held the belt.
• Champions defend at most twice a year. Defenses are worth more than the belt itself in the Hall score (5.5 each versus 13).
• Finishes matter: KOs and submissions add to the score, and the record ticker tracks 13 KOs (ties the all-time record) and 11 defenses (ties the record).
• One injury per career; the usual decision events plus a title-shot event.

The Hall of Fame

Otherwise: wins × 1.15, belts × 13, defenses × 5.5, pound-for-pound #1 years × 3.5, KOs × 1.15, submissions × 1.0, fight-night bonuses × 0.7, KO and Submission of the Year × 2, rolled against (score − 72) / 42.

Verdicts, rarest first: 0️⃣ Retired Undefeated (a perfect record), 🐐 G.O.A.T. (Hall with 170+ points and 5 belts, or 11 defenses, or 3 belts with 8 defenses), 🏆 UFC Hall of Fame, 🥊 Hall of Highlight Reels (12+ KOs, never champion), Perennial Contender (80+), Hall of Mid-Cards (72+), Hall of Early Stoppages. Vote line: 75 + 0.14 × (score − 95) + 1.5 per belt, first ballot at 90% or three belts.

Tips

• Striking, Grappling, Wrestling. The three 1.2 slots decide OVR; the icons' best numbers live there.
• Cardio is fights per year and years. More fights means more wins, and wins are the biggest single term in the Hall score.
• Get the belt early, then defend. The second title shot is half as likely, but defenses at 5.5 points each pile up fast; six defenses alone is an automatic Hall.
• Chin buys the late career. It is the second longevity term and it keeps you off the Early Stoppages verdict.
