Vanguard
As the demon ravaged the warrior's core, the behemoth kneeled and stood silent, a lowly animalisting grunt escaping him as his soul began to be defiled by the demon. His rage was incomparable to anything he felt thus far, even what Surien subjected him too was but a calm lake compared to the inferno boiling within. The maddening grinding of gears, a rusty metallical growl could be heard from the depths of Vanguard's being. Then, without warning, he laid his hand upon his face and clutched it.
"F̤̌̈̃ͨ̃̎͑͞o̅̍͆̐̈̾̕ö́͌̽̍̈́̚҉͓͚̤̬̘͚ͅl̘͇͓̾͋̂ͩ͢", muttered vanguard in a voice unheard of, of a tongue unknown to man. As soon as he spoke, the air itself froze in a deathly manner, as if to choke all in it's vicinity. Without warning, the warrior's whole body erupted in a shrilling sound, lightning seeping from every inch of his body and bursting from within.
That demon had the audacity to think himself worthy to topple him, and he would pay a price worse than death. Trapped in the prison that was his vessel, he would not escape, the lightning seeping from all over his body trapping the foul demon as it shattered all presence with thunderous might. Yes, the demon would be harmed by the magical energy that burned and creaked madly, and even if he was to escape, Vanguard would pummel him down as soon as he saw the beast.
