Jack barely avoided a blast of magic from his opponent. Rolling away from another blast he aimed his pistols and began firing, he managed to get a few shots in before his opponent put up a shield. Charging forward Jack pulled a small metal ball out of his pocket and threw it at the figure. When the ball hit it gave off a blinding light which caused his opponent to stagger. Seizing the opportunity Jack held one pistol by the barrel and smacked the figure in the head with it.

As his opponent got to his feet Jack dashed over and kicked him in the jaw, sending him flying into a wall. As the dust settled and the figure appeared to be stuck, Jack walked forward to get a better look at him. With the dim light it was hard to make out the figures appearance. Fishing around his pockets he pulled out a small ball and held it out. It rose into the air and lit up that area.

The figure broke out of the wall and fell to the floor, damaged by the battle but with his wounds quickly healing. Jack looked at the figure and his eyes widened. "Metal?"

Metal was now in his Neo Metal form except his metal was black and his eyes were glowing orange and he had a dark red aura around him. "Took ya damn long enough to realise." Metal got to his feet and punched Jack away, the ponies couldn't get a view of the battle at that moment, as Metal had put a wall in front of the cage.

Jack got to his feet and stared Metal down. "Why are you suddenly working for Mephiles? Why did you put us through all of those challenges?" Jack ran forward and punched Metal in the face, then the two entered a battle of strength as they pushed against one another.

"I have my reasons, I never wanted to do any of this!" He grabbed Jack by the arms and spun him around, throwing him against a pillar.

"Then why?! You know how dangerous Mephiles can be and how evil he is, so why help him?!" Jack jumped and kicked Metal in the face.

"Because he's got something that means the world to me!" Metal curled into a spindash and hit Jack in the chest.

"Then I'll help you get that thing back!" Jack pulled out his his pistol and shot Metal in the eye, causing him to stagger. Not letting him recover Jack shot forward and began to beat the living hell out of the blinded robot.

"ENOUGH!!!" Metal used a small Chaos Blast to caused Jack to go flying, hit the ceiling and then drop back down. "It's not that simple. The thing he has... it's a person, if I go against him he'll kill that person."

The two stared each other down before walking towards each other. As they were about to enter another test of strength Discord appeared and knocked Jack away.

"What are you doing here Discord, you're supposed to be with Mephiles!" Metal shouted in annoyance.

Discord chuckled evilly before glaring down at the metal hedgehog. "I'm sorry Metal, but Mephiles is no longer in need of your services." Discord handed him a pink slip before blasting him across the room.

Meanwhile Jack got up and watched the two beings engage in a brawl. "Jack."

Jack looked over his shoulder to see Author walking over to him. "Who're you?"

"My name is Author. I am Metal Sonic's displacer, I'm afraid it is time for you to leave."

"What? But we haven't killed Mephiles yet!"

"We will take care of Mephiles, we have powerful allies that will come to our aid if Metal is unable to destroy that monster. You being here has notified me and my council of Mephiles and all of his other counterparts, for that I thank you. Take this as a reward." Author reached into his coat and pulled red plated versions of his guns.

"Um, thanks I guess." Jack took the guns and Gilda appeared beside him. "You ready to go babe?"

"Yeah, those challenges were fun and all but I'm not one for all of this betrayal stuff."

Jack turned to Author and nodded. "Ok, if everything is under control here then we will be on our way." Author nodded and a portal appeared beside him leading to their world. "Oh, and tell Metal he's an asshole, but a good opponent nonetheless."

"I will, now get going, you are needed back in your world."

Jack looked back at the fight and sighed. "Well this wasn't a complete waste of time if we got a powerful group to deal with Mephiles and I got these new guns. Tell Metal I said goodbye." With that the hedgehog and the anthro griffin jumped into the portal. Author closed the portal and disappeared through his own.

Metal blasted Discord and charged up a spindash. Shooting himself forward at Mach five speeds towards his opponent and sending both of them flying outside the castle. Discord but his hands together and knocked Metal to the ground. "You know the first thing I'm gonna do when Mephiles gives me that precious little human you care for so much?" Discord put his foot on Metals back to stop him getting up. "I'm gonna give her to a pack of pent up Timberwolves who will violate her and then tear her apart, and I'll keep bringing her back, every time until I get bored and find something else to do to her."

Metal froze, his anger built up beyond belief. "Like... hell... you... will!" Metal teleported out of Discords hold and summoned a fleet of battleships. Purring his hand up he shot a pillar of lightning into the sky what I struck all of the airships and the pieces of said ships all floated towards Metal.

The group of mobians and ponies had broken out of the cell and watched from the floating island as Metal transformed. As the huge figure towarded over him Discord frowned and summoned a fireball in his paw.

"Now Discord... I SHALL BE YOUR END!!!"

Author's Notes:

I know that this wasn't a great way to end a crossover but it had to happen, the story that was crossed over with is no longer a priority for the author and there was no real reason to continue. This was the final chapter of the crossover with In The Shadow Of A Doubt by Joker the Hedgehog

We will now begin The Wolf arc in the next chapter, stay tuned my loyal readers and followers
