5 undefeated UFC fighters with the most wins

#2 Alexander Romanov (16-0)

The UFC heavyweight division is often described as one of the promotion's most barren weight classes due to its relative shortage of elite fighters, compared to the deeper talent pool seen in lower divisions.

However, the current crop of heavyweights has injected new life into a division that was once defined by older fighters struggling to recapture their former glory. While the division's previous undefeated phenom was Ciryl Gane, his spotless record has since been blemished by a loss to former training partner Francis Ngannou.

In the wake of Gane's defeat, Olympic freestyle wrestler Alexander Romanov has risen as the latest undefeated heavyweight. Romanov, however, is no smothering wrestler with a lay-and-pray game designed for neutralization and nothing else.

He is a constant submission threat who has only ever gone to decision once in his career. On the ground, he resorts to a wide range of submissions like neck cranks, forearm chokes, keylocks, and rear-naked chokes. It has aided him in amassing a record of 16 wins and 0 losses.

#1 Jack Shore (16-0)

Former Cage Warriors champion Jack Shore is a force to be reckoned with in the bantamweight division. He possesses a well-rounded grappling game enforced by his determination to secure takedowns against everyone he faces.

He is both an opportunistic wrestler and an aggressive one, coming forward to pressure his opponents into reacting with a wild swing that he can duck under.

Once Shore secures a grip, he doggedly pursues takedowns, using chain wrestling and a myriad of trips and suplexes to ground his opponents. While he creates his own openings for takedowns, he also capitalizes on openings that his foes expose.

On the ground, he actively seeks submissions, using ground and pound to force his opponents to stop defending submission attempts, enabling him to secure chokes and armbars. He's proven successful in the UFC and his MMA record sits at 16 wins with 0 losses to his name.
