In the spirit world; lots of spirits were in some type of courtroom as Jules the Hedgehog was standing in front of a podium with five Mobians on it. One was a male fox, the second was a male gorilla, the third was a female goat, the fourth was a male shark, and the fifth was a male hawk.
"Jules the Hedgehog; you are charged with disobeying the rules and regulations of the spirit world, interacting with living beings, and almost endangering the life of a teenage boy who just so happens to be your son and loads of others. How do you plead?" the gorilla judge said.
"You see me as someone who is guilty, but very few see me as someone who just wants to help others out no matter what." said Jules.
"You broke the rules of the after life in order to help your son stop a great evil we swore to never speak of ever again, is this true?" said the goat.
Jules nodded.
"It is true, but I had my reasons for doing it." said Jules, "The great evil as we once knew as Killjoy posed not only a threat to my own planet Mobius and the planet of my son's friends Earth, but to the entire universe as well. Which is why I had my son train to stop him once and for all"
The judges nodded.
"Now this Killjoy we swore to never talk about, he managed to kill one of the greatest shortly after being released right?" said the shark judge.
Jules nodded.
Then the scene flashbacked to two weeks earlier; Sonic and Leo entered Wes Green's museum with a weapon that looked like a Decepticon Hunter.
Sonic smiled.
"Good thing Kai sent us to her grandfather's museum in order to find out what this weapon we found in that Egyptian temple is." said Sonic.
"Yep." said Leo.
Wes Green appeared and saw the two.
"Good to see you. Kai told me you'd be coming." said Wes.
Leo smiled.
"I read about you and it's a honor meeting you." said Leo.
"Same here." said Wes.
Sonic gave Wes the device and he inspected it.
"Looks Cybertronian, but it's not. This is Mobian engineering, something they call a Neurotransmitter Weapon. It connects to the users Neurotransmitter and creates a weapon of the users thoughts." said Wes, "It's been around since the time of the Ancient Egyptians."
Sonic took the weapon and it turned into a cross bow before shooting a round at a anamatronic statue of Wes.
Sonic became shocked.
"Oops." said Sonic.
Wes is shocked.
"I just had that thing instald." said Wes.
Sonic pulled out a roll of hundred dollar bills and gave it to Wes.
"That should cover it." said Sonic.
He and Leo left the museum.
Meanwhile in Vilgax's ship which was over Earth; Vilgax was on the outside deck of his ship.
"Glad I bought the atmosphere upgrade to this ship." said Vilgax.
Suddenly; Psyphon appeared pushing a big body casket towards Vilgax.
"Master, I couldn't find what you wanted, but I did find this casket." said Psyphon.
Vilgax turned to Psyphon with anger.
"You fool, I told you to bring me that Neurotransmitter weapon from inside that temple." said Vilgax.
Psyphon backed away in fear.
"Forgive me master." said Psyphon.
Vilgax started to approach Psyphon.
"The only reason I allowed you to rejoin me was because you kept on kissing my feet." said Vilgax.
He stopped when he saw that the casket had a pulse monitor on it and that it was beeping.
Vilgax smiled.
"But whoever's in here must know more stuff about the Neurotransmitter weapon. Awaken the unfortunate prisoner." said Vilgax.
Psyphon bowed down.
"Yes master." said Psyphon.
He was about to open the casket, but a very big ship appeared and a villain named Lord Dominator in armored form (Wander Over Yonder) appeared.
"I don't think so." said Dominator.
Vilgax and Psyphon became shocked.
"Who are you?" said Vilgax.
"Lord Dominator, the greatest in the universe." said Dominator.
"You're nothing compared to Lord Vilgax." said Psyphon.
Dominator chuckled.
"I became the greatest during that Lord Hater's time trying to capture that goody, goody Wander and take over Earth." said Dominator.
Vilgax chuckled.
"I've destroyed lots of planets, and made it my life long goal to steal the Omnitrix from Ben Tennyson." said Vilgax.
Each side started arguing before the casket was banged open from the inside.
The three villains became shocked before turning to the casket.
Steam came out of the casket and a strange figure came out of it.
Only a silhouette of the figure was shown before it came out of the smoke, revealing a figure with a body like Knuckles, but dressed like Darth Vader complete with a purple helmet, cape, outfit, and boots.
"You're nothing but a bunch of incompetent fools. I was the greatest in the whole universe before my own brethren imprisoned me." the figure said in a voice similar to that of the Revenge of the Fallen version of Megatronus.
The other villains stepped back in shock.
"Who are you?" said Dominator.
The figure chuckled.
"I'm called Killjoy." the figure known as Killjoy said.
Vilgax scoffed.
"And why is that?" said VIlgax.
"Because I never leave anyone I fight alive." said Killjoy.
Vilgax scoffed.
"Yeah right, what next, you-"Vilgax said before Killjoy pulled out a sword and stabbed the squid in the heart.
Vilgax gasped in pain.
Psyphon became shocked.
"Lord Vilgax, no!" yelled Psyphon.
Vilgax fell and exploded.
Killjoy chuckled before using telekinesis to levitate the dead Vilgax over the side of the ship and drop him down to Earth.
Psyphon became mad.
"You murderer." said Psyphon.
He charged at Killjoy in anger.
But the evil being used his powers to stop Psyphon in his tracks and bashed him on the ground.
Dominator pulled out a slushie and tube of popcorn before turning into his true form, revealing that 'he' was actually a 'she'.
"Awesome." said Dominator.
Everyone was shocked.
"You're a woman?" said Psyphon.
Dominator scoffed.
"Yeah, some creepy skeleton, and some friends of his think I'm a guy." said Dominator.
"It still doesn't change anything. Not only do I kill guys, but I also kill women." said Killjoy.
Everyone was shocked.
"Even children, my own kids as well." said Killjoy.
He then let go of Psyphon.
"However; I'll let you two live." said Killjoy.
He turned to Earth.
"A lot has changed since my imprisonment. The weapon I brought over here centuries ago has been hidden, and I need to find it." said Killjoy.
He grabbed a staff like Megatronus's staff from Revenge of the Fallen before turning to Psyphon and Dominator.
"Join me, or the squid. In return for your services, I'll give you the one thing you each desire the most." said Killjoy.
Psyphon and Dominator looked at each other then back at Killjoy.
"How do we know you won't kill us?" Psyphon and Dominator asked.
Killjoy was about to say something when he realized that Psyphon and Dominator made a good point.
"Good point." He said
He pulled out two contracts and gave them to the two villains.
"These contracts will keep me from killing the two of you no matter what, unless one of you tries to betray me." said Killjoy.
Psyphon and Dominator looked at each other and smiled.
"Deal." Psyphon and Dominator said.
Killjoy smiled underneath his helmet.
"Cool." Killjoy said. "And don't worry I always keep my word when it comes to contracts."
He turned back to Earth.
"The first phase of my plan is to find that weapon, then bring down some of earth's government agencies, then find the one who betrayed be, claim the key to powering up the weapon, then finally take the planet's energy as my own and do the same thing with Mobius." said Killjoy, "Both planets played a part in my demise, now the inhabitants of both worlds will pay."
