This maybe empty gas but the itsumade (Mar's creature) is slain in folklore by 
Kabura-ya, or turnip headed arrow. Yamato has a move 
Narikabura, which is another name for 
Kabura-ya. Oda also thematically likes clashes between fire and Ice with Aokiji and Yamato clashing against Ace, and Yamato clashing against her father’s Bolo-Breath.
