Demon!Eliot - Booth
It was disturbing just how much he still sounded and looked like Eliot. The way he spoke was the same, the way he moved. But he had to keep reminding himself that it wasn't the Eliot he knew. His friend wouldn't do this. It was harder than he expected and he had to try not to take anything he said to heart. It wasn't that easy when the monster didn't have the face of a killer as Booth had always imagined it when he was a kid in church. Demons with contorted faces and horns and pointy tails. It was nothing like that. They were whoever they took over and he wasn't trained for it. He remembered a case where a teenager had bone Devil horns attached to his skull, and even that shook him. This was what terror felt like. His faith shook, these were hell demons with hell hounds.
The first punch landed and Seeley's head jerked back caught off guard while his mind was still processing the fact that it wasn't Eliot. "Don't get used to it. You're not staying." His own deep hazel colored eyes narrowed on the darkness of Eliot's. He didn't let it stop him, he couldn't for Eliot, or the other complex fighters. The closed fist stung when it made skin contact and he touched his face for a second as the heat died down. He was going to feel that later he knew it.
The stunning didn't last very long, it snapped him out of his daze infact and he threw the next. And the next after that, a combination of swings and uppercuts. Different attacks in attempt to throw him off.
