"ARGH!!!" Mephiles got hit by a purple energy blast from behind. The person that knocked him on the floor was Nebula. Eyes glowing purple from her anger while her fists are making purple energy blasts. She glared at the evil alien that almost tried to kill Rouge.

"Leave her alone!" Nebula snarled.

"You!" Mephiles yelled and fires a white beam at Nebula, but she dodged and tried to fire again, only for Mephiles to turn into dark mass.

"GET BACK HERE YOU MONSTER!!!" Nebula tries to tackle him but unable to hurt him through the floor, "What the? WHOA!!" she jumped away from her shade that moved by itself.

"What the hell?!" Shadow gasped.

"HAHAHAHA!!!! You can't touch me, my dear" Mephiles was now Nebula's shadow on the wall and it's impossible to touch him.

"ARGH!!!!" Nebula tries to beat him up but is unable to hurt him. All she did was punched the walls to hurt Mephiles but nothing is working, "Show yourself coward!" Nebula yelled.

Then Mephiles showed himself and punched Nebula hard. He goes up to her and puts his hands on his hips,

"You want my best? Well you are no match for us!" Mephiles said. He then creates different shadows on the floor and out of them came clones of Mephiles.

"Oh, shit!" Rouge was horrified.

"Rouge, get out of here!" Shadow yelled and managed to move the heavy vent off her foot.

"Okay!" Rouge said and flies out the room to alert the others in the base. The Mephiles clones proceed to attack Nebula and Shadow by using their lethal energy beams.

Shadow and Nebula dodged the beams and tried to punch and dash through them. But every time they do that they go straight through them.

"We cannot touch them, but what if we use our energy attacks" Shadow said, a chaos spear formed in his hand.

"Yeah, good idea Shadow!" Nebula smirks and fires her purple energy blasts at the clones of Mephiles along with Shadow firing his chaos spear.

"ARRGH!!!" the Mephiles clones screamed.

"It worked, now let's finish them!" Shadow said and jumps up in the air using a black tornado attack, "Chaos Blast!" he fires a large wave at the clones in the tornado knocking them at the debris and the walls, some of them were impaled by sharp pieces of the remains of the glass containment.

"There's gotta be something to seal him without having him to escape again" Nebula said.

"But how? He can phase through glass!" Shadow said.

The real Mephiles laughed maniacally and then looks at the two, "There's nothing you can do to stop me! Because I got a world to conquer!" Mephiles said, "By the way, Shadow. You really don't remember me, do you?"

"What are you talking about? We haven't met before? And why should I remember?" Shadow growled.

"You'll find out sooner or later. Ta-ta!" Mephiles teleported out of here.

"NO!!!" Nebula tries to tackle him but he was gone. She then looked at Shadow in confusion, "What was he talking about? He knows you?" Nebula asked.

"Nothing rings a bell, Nebs. I don't remember him from before" Shadow said in confusion, "I can't even remember when I was a child. This doesn't make any sense"

"We'll find out later" Nebula said.

Mephiles was now far away from Station Square, he was now too weak at day time since he didn't look pretty awake, "Must....have.....power at night" he said in an exhausted voice, "How can Shadow forget me? I was his best friend when we we're children. Hmph, I'll say his father erased Shadow's memories about me"

He then came into a cave in some cliffs in the forest to regain strength after being in the fight in G.U.N base with his clones. He sat down on the ground folding his legs together, "When I'm at full strength I shall visit an old friend of mine!" Mephiles' eyes glowed a bit when he said that. He looks at the horizon and gives an evil stare.

At Silver's house, Raven was singing 'Let It Go' from the movie Frozen to her baby brother. For a young hedgehog she was a very good singer like the American child singer Kaitlyn Maher.

"Ga...ga..." Neptune clapped his hands at his big sister's amazing talent.

"Thank you very much Neptune" Raven bowed for Neptune.

Silver came in to them, "Neptune and Raven. Your parents are here" he said.

"Mommy! Daddy!" Raven ran up to her parents.

"Hey Raven!" Shadow picked his daughter up and hugs her. Then he placed her down to let her hug Nebula, "Wait for a moment, I need to ask Silver something" Shadow said to Nebula and Raven before picking up Neptune and gives him to Nebula who just let go of hugging Raven.

"Okay" Nebula nods.

"Silver, check my memory if I know something about Mephiles. He says he knows me" Shadow said to Silver.

"You say so? Well let's do it" Silver made his pupils glow and placed on Shadow's forehead to check his memories that are fogged up as a sign of forgotten.

(Shadow's Childhood Memories)

Young Shadow as a child on his home Planet Doom was playing with and old friend; an amorphous entity of Young Mephiles. They have been best friends for who knows what.

"So what happened to your other friend Iblis, Mephiles?" Young Shadow asked.

"I don't know. I heard rumors on my home planet say that Iblis disappeared or either went to a different far away in the galaxy" Young Mephiles said.

"That's terrible. I never traveled that far into the galaxy. My dad forbids me to leave my home planet" Young Shadow said.

"That's a problem. You should see some of the planets I've been into green lava at some and it does not burn Ibils" Young Mephiles said.

"Cool. On this planet pretty much life here is dead. Only a few lifeforms lives here. Odd that this planet has no sun" Young Shadow said.

"We'll see. Now it was fun seeing you Shadow. See you next day. Hope we'll be best friends forever" Young Mephiles said and flies away.

"Yeah, we might become the most powerful in the universe!" Young Shadow waved.

Later that night, Young Shadow was sleeping in his bed and he was unaware that Black Doom has witnessed that his son is friends with Mephiles, believing that the two might overthrow him together. He reaches out his hand over Shadow's head and casts a dark magic spell over him while he's asleep. After a few seconds, the spell on Shadow disappears.

"Now that shall prevent him from overthrow me from my ruling of this system" Black Doom thought.

The next day, Young Shadow was on a walk in the deserted area and he saw Mephiles, but oddly he only blinked at him.

"Hi Shadow. Want to talk about our future again?" Young Mephiles said.

"Who are you and what are you talking about?" Young Shadow blinked in confusion. This shocked Young Mephiles.

"Shadow, it's me Mephiles. Don't you remember?!" Young Mephiles asked him.

"No, and to my father's order I never hang around with anyone!" Young Shadow said. This made Young Mephiles angry, realizing that Black Doom has done something to Shadow.

"Your father! He will pay for what he has done to your memory!" Young Mephiles yelled, "One day I shall have my revenge!"

"Get off of my planet, creep!" Young Shadow snarled and transformed into his Black Arms hedgehog form, "*SCREEEEEEEEEEEECH*" he screeched out loud.

"NEVER!" Young Mephiles fires a white beam at Shadow to stun him, "I will have you back as my comrade one day! You'll see!" he screamed and teleports away.

(End of memories)

"What? Mephiles and I were best friends and my father erased my memory of him being my friend. Damn, if he didn't erased my memory I would not be here right now" Shadow said.

"That's terrible. And who is this Iblis that Mephiles was talking about?" Silver asked.

"Some fiery alien that was a close friend to Mephiles. He mysteriously disappeared and nobody knows where he is now" Shadow said.

"Well let's hope he doesn't appear too" Silver said.

"Yes. I need to drive home with my family right now. Thanks for taking care of my children" Shadow said.

"You are welcome" Silver said.
