On record, this is a one-sided series. Garry Tonon holds a 4-0 edge over Dante Leon across four recorded meetings, three of which came in 2020. Their first encounter came earlier, at the 2019 ADCC World Championship in the 3rd place match, where Tonon finished the match by Outside Heel Hook. The other three all went to decision, at 2020 WNO and Fight to Win 148.

The stylistic split shows up in their finishing tools. Tonon is a leg-lock hunter whose most frequent recorded finish is the Heel Hook with 14 wins, and it was leg attacks that produced the only stoppage in this series. Leon leans on backtakes and pressure, with the Rear Naked Choke his most common finish at 24 wins. Against Tonon, Leon could not convert his own game and was forced to grapple in the openings Tonon prefers.

Both men carry strong overall numbers. Tonon has a 72% win rate over 108 recorded matches with 63% of his wins by submission, while Leon sits at 68% across 170 recorded matches with 57% of his wins by submission. The head to head, though, does not reflect that closeness. Every meeting went Tonon's way, and only one required a finish.
