Zaphkiel
Mid flight, the archangel was flipped backwards by the sonic blast of Shrieker just before his body crashed into his form. One villain down, he assumed, quickly picking himself up from the ground. At the sound of the first shot of gunfire, Zaphkiel engaged his shield, expanded the protective surface it sported to a much greater surface area. He turned the shield in the direction of the greatest concentration of fire, dismissing the bullets impacting his shield easily. The others clanged upon his armor, bouncing off harmlessly for the most part. Still, the force of their fire agitated his stance a bit, hindering his ability to gain perfect footing.
The knives, on the other hand, presented absolutely zero danger to the armored angel. Regardless of the keen throwing arm they originated from, Zaphkiel would not be penetrated by such mundane bladed weapons; bullets at such a close range were one thing, but the common knives of humanity were but play toys to his fortitude. He simply ignored Stalker's attempts at harming him, stretching his wings out in preparation for a coming gale. With a grunt, he jerked his torso forward, followed by his wings to create a powerful gust knocking the firearm-carrying lackeys off their feet.
Zaphkiel turned his attention to Ghost, an unawares of his abilities, threw his elongated hand into a thrust at the villain, hoping to punch the evildoer right in the kisser.
Killjoy
As fiery and wonderful as it was, the screams of innocents was an utterly unfortunate tune amidst the crackling of flame. Killjoy might have been a pyromaniac, but she was no serial killer, and definitely wouldn't employ such terrible means to take another's life. Her own weapon was indeed flame, and for that reason she realized her skills were rendered practically useless in this situation. Her taser would likely burn up before reaching the alight villain, and her flamethrower would only... add fuel to the flame.
Killjoy barely stifled a laugh at the pun. What else could she have done then? It took a moment, but she gathered an idea. For the first time in her life, Killjoy considered doing something utterly contrary to her very being; she would try and put the flames out. Killjoy darted down the hallway for a nearby fire extinguisher, returning in a hurry to hopefully quell the ensuing inferno. With the magician and pyromancer occupied, Killjoy rushed about, dousing still-living innocents in her life-giving fire-deprivation device, as well as the fires that clung to the room's interior.
