Hey everyone. This story was written for both The Camp Activites Challenge, and The AU Challenge on Percy Jackson Fanfiction Challenge. For The Camp Activities Challenges I used the prompt for Volleyball which the task was Write an AU story. For The AU Challenge my AU was a zombie Au so I decided to do this as both an AU and a crossover fic with The Walking Dead. I hope you all enjoy the first chapter of The Demigod Walking Dead.

Fighting back to back the son of Hepheastus and the son of Mars worked together like a well oiled machine. Or least that is how Leo looked at it. They at least had one common goal. To get through the zombie hordes and make sure that their friends were safe inside Camp Half Blood. Looking over his shoulder he could see that Frank was looking towards the barrier to the camp. Following the other boy's eyes to the tree line he saw Hazel, Frank's "girlfriend" waving them towards the barrier.

"Do you think we can make?" Leo asked Frank as he took out yet another zombie.

"Maybe," Frank called back over his shoulder. "But if we're doing this we should do it now. I don't think we'll last much longer out here."

Leo nodded knowing the other boy couldn't see his nod but knowing that Frank felt it. "So do we go on the count of three?" he asked jokingly over his shoulder.

"Nows not the time for joking, Leo," Frank's voice floated back to him matter of factly. "We go now."

Leo felt Frank's hand go into his and then he was being pulling across the ground. Gathering his own strength Leo found himself running along side the son of Mars. Both of them taking out zombies that crossed their path.

"Almost there," he heard Frank whispering to himself as he took out zombie after zombie.

"Frank," Hazel was by their side now. Neither boy saw her leave the safety of the camps borders but they did see the zombie that bit into her arm. They heard the ear splitting scream that left her mouth.

Seeing Frank stop running Leo scooped up a heavily bleed Hazel grabbed Frank's hand drug them both to safety. He set Hazel down and looked to see how bad the injury was. He wasn't expecting to see that half of her shoulder was missing. Or feel a pang of guilt and sorrow for the Daughter of Hades. He could see she wasn't going to last long.

"You shouldn't have come out there, Hazel," Frank told her tears falling down his face. "You should have stayed behind the barrier and we'd have made it to you in no time."

"I know," Hazel got out with great difficulty. She turned her fading eyes on Leo. "Take care of our boy, Leo. Promise me. Promise me you'll take good care of Frank."

"I promise," Leo whispered. He turned to the Apollo camper who'd come over to help with Hazel. "There's not much time. You have to find Nico di Angelo and get him here before she dies."

The girl nodded and went off in search of Nico. Leo turned back to Frank and Hazel he felt bad about what Hazel had said to him. How had she known about his feelings for Frank? How had she known anything had happened between the two boys? He almost smacked himself because he should have known. Hazel had this funny little way of knowing everything that involved Frank.

"I don't think we have much longer," Frank muttered looking up at Leo.

"She has to hold on until Nico gets here," Leo told him. "She has." He knelt on Hazel's other side as he heard campers muttering about something or other. He didn't really care what they were muttering. He just knew that Hazel had to wait for Nico. Nico would be broken if Hazel died without seeing him again.

"Where is she?" he heard Nico's voice as though from a far away land. "Where is Hazel?"

"Near the border to camp," he heard Percy answer as he lead Nico and Annabeth over.

Nico dropped next to Hazel on her other side. He didn't bother to glance over at Frank or Leo for that matter. Leo got to walk a little way off and give Nico and Frank time to say good bye to Hazel properly.

"Don't go," Hazel told him grabbing his hand.

"But he stole..."

"He didn't steal anything, Nico." She turned to Leo. "Please stay."

Leo nodded and sat back next to Frank. He felt Hazel put his hand into Frank's. Yet again he wondered how she knew about them? How she knew what had happened between them on the road?

"I'm sorry, Hazel," he whispered.

"Don't be," she whispered. "I want you and Frank to be happy. For me." She turned to Nico. "Please don't be mad at them because of me, Nico. They belong together." Her shifted closed with that.

Leo was to stunned to even comprehend what was happening going. But he did know that Frank must have taken Hazel out because he and Nico were now rolling around the ground throwing punches.

"Stop right now," Chiron's voice called out making both participants stop in their tracks. "What's going on here? What happened?"

"The end of the world," Leo heard himself mumbled as though from a far of land. That's all he remembered before he passed out his head hitting the ground hard. He knew that was going to leave a mark.

I hope you all enjoyed the first chapter of The Demigod Walking Dead.
