Hellblaze

is a demonic enchantment possessed by the Dragon's Sin of Wrath, Meliodas; and the Great Holy Knight, Hendriksen.

Description
Hellblaze is dark and mysterious power connected to the Demon clan. The enchantment allows the user to generate and control black flames that cannot be extinguished. In addition to its immensely devastating power, the flames also nullify the regenerative abilities of an immortal. In battle Hellblaze can be imbued upon weapons to drastically increase their destructive potential, hurled as fireballs at an opponent or used in hand-to-hand combat.

Meliodas

 * A powerful attack that requires Meliodas to heighten his power and senses to the utmost limit. As black flames engulf his sword, he leaps into the air and slashes; hurling them in a single, ruinous attack.

Hendriksen

 * Hendriksen points his sword towards the opponent and engulfs them in a wild, black inferno.

Trivia

 * The only known person who was able to put out the flame was Merlin.
