The flaming dragon is the attack with the greatest initial AOE of all and lethality. Initial AOE (Area of Effect) is the initial size without taking into account shockwaves afterward. The carpet that the Flaming Dragon creates is two to three times larger than Luffy's fist, which was comparable to Onigashima size. In summary, the flaming dragon, with its carpet of flames at the same temperature as magma, is the size of three or more Onigashimas.
To escape from such an attack, the opponent needs to cover a distance of three or more Onigashimas before the attack lands and hits, which is impossible. Even the admirals, despite being Logia users, don't have anything at this level. LMAO.
