Heikon 24%
A moment after the warning had left his mouth, Heikon got hit full on by the monster's tail and was flung into a wall. The wall received a sizable crater, but a second later, and the armored man pried himself loose.
"Well that's not something I'm keen to experience twice." Heikon aimed his cannon arm at one of the monster's heads, only to see it get exploded by an arrow, and then grow back with a friend...
"Facsinating, if it has a healing factor that large, this could get complicated..." he turned to the other two,
"Keep him busy! I need a minute!" Heikon knelt down on one knee to brace himself for what he had planned, It wasn't going to be easy but it would take care of the beast. He switched his helmet to mute so the other's wouldn't hear him.
"Charge Unmaker." His helmet's computer responded,
"Warning! Power consumed by Unmaker will leave the power armor at less than 10% power. Override code requi-" Heikon cut off his computerized warning speech.
"Override code: Hellfire. Charge the damn cannon!" Energy from every system in his suit of technology began to focus in his cannon arm, causing it to give off a light of increasing intensity, It would be about thirty to forty-five seconds before it would be charged, and another ten to fire it, and Heikon had to remain still or else the cannon engulfing half of his right arm could very well explode... It was going to be a long minute.
