In the Enies Lobby Arc, Sanji reveals a new ability – Diable Jambe, the power to heat his lower legs to a temperature so high that they glow bright red, by spinning rapidly in place, which causes his attack to be more powerful. The heat of his attacks is so high that contact for even a second could set a person ablaze. Diable Jambe has improved to the point that his entire leg is now enveloped in large flames.
Sanji can harden his legs with Busoshoku Haki. He didn’t actively display this ability until his fight with his father, when (much to Judge’s surprise) he hardened his right leg in order to block one of his father’s spear attacks.
