A/N: This one is also from a word of inspiration from Written Parody. Again, the word prompt made me instantly think of a character, that being Jay. An obvious choice, no doubt, but there's so many ways that Jay is both invincible and extremely vulnerable. I hope I've captured this well.
Invincible
Jay crashed through the wooden fence with the force of a stampeding elephant, and the grace of a drunken sloth. The palings snapped and splintered, along with three of the bones in his right hand as he flung it out for support.
He gasped as the pain shot through his hand; up is arm in stabbing flashes. It wasn't the worse injury he'd had, but it was enough to be considered bad. Very bad. His right arm was his sword arm. The broken bones were just as crippling as a broken leg or arm.
In front of him, the sound of the melee continued. His short flight through the air curtesy of Agnon went ignored as his team continued to fight. Archie and Atlanta had already taken down one of the giants, and Herry was in the process of finishing off another. Theresa and Neil had taken over his position against Agnon, and he watched them hurtle away as the giant swept them away in one blow of his colossal arms. They both got up, a little shaken, but ready to continue the fight.
He'd always said to them; if you get hurt really badly, stay down. Of course, they'd never followed that advice. If anyone got hurt in a fight, they'd get up and keep going.
With a small groan, he pushed himself to his feet, using his left arm to propel himself out of the wreckage of the fence. He found his sword, swinging it in his left hand. The movement did not feel uncomfortable, but was unknown to him. Still, he could learn as he went. He stumbled back into the fight, ready to fight again.
Jay was not invincible, but, for now, he would act like he was.
