Mephiles held his hand out and a cloud of dark energy emitted from it. Then the dark energy formed into a sword.
"Let's see how Mekka's sword compares to my Dark Energy Saber." Mephiles said, holding the sword out, tip pointeed at Jason.
Jason went in for the attack and the two were locked in combat. Jason swung his sword and Mephiles dodged it, countering with kick that knocked Jason into the wall. He could see Wave trying to get up in the next room through the giant hole next to him. He finally came to and noticed Mephiles had executed a jab attack. Jason rolled against the wall, didging the attack and causing Mephiles to stab the wall. The Dark Energy Saber cut through the stone wall like a knife through butter. Jason tried to attack with his sword but Mephiles quickly slid his Saber out of the wall and blocked it. The two were now in a sword-lock, each one trying to out-power the other.
"How come you're so good with a sword?" Jason asked. "Mekkaku, I understand. But you-"
"Mekkaku was a robot." Mephiles said. "Who do you think programmed him?"
"The military?" Jason asked.
"No. Me." Mephiles said. "The army may have created him but I gave him life."
"You gave him life?" Jason asked.
"I needed someone to fight you to know who I was up against. Mekka proved to be the perfect test subject."
Mephiles broke the sword-lock and Jason stepped back, dodging an attack from Mephiles. Jason moved closer to the chemical pool while blocking attacks from Mephiles. Mephiles stopped attacking and Jason looked behind him. He suddenly had an idea. Mephiles took a step back and ran at him. Jason stepped out of the way and Mephiles went past him.
"Have a nice swim, Meph." Jason said.
Mephiles went off the edge but instead of falling in, he hovered over it. Mephiles let out an evil laugh.
"Did you really think I'd fall for that, Jason?" Mephiles asked.
"Apparently not." answered Jason. "Couldn't hurt to try."
"True." Mephiles agreed. "But then again, you were never the one to plan ahead."
"Huh?" Jason asked. "What's that supposed to mean?"
"You have no idea what I'm capable of do you?"
"Oh, I think I've seen what you're capable of." said Jason.
"Oh, really?" said Mephiles. "You haven't seen anything yet."
He shot a blast of dark energy at the ceiling. It started to crack and chunks of cement came crashing down. The ones that fell into the chemical pool vaporized. Must be acid, thought Jason. The ones that were about to hit him, he caught with psychokinesis. Mephiles had turned into a cloud of gas, causing the cement chunks to fall right through.
"That's cheating." Jason said, catching and throwing the falling debris.
He noticed something weird. There was no sunlight shining through the holes. There was another floor above them, though it wasn't really a floor. Once the ceiling finished collapsing, it revealed catwalks and platforms. Mephiles solidified and floated up to one of the catwalks.
"What's the matter, Jason?" he asked. "Afraid of heights?"
"No." Jason said, using psychokinesis to use one of the cement chunks as an elevator. "Just falling from them." He stepped off the cement chunk and onto the catwalk.
