Roman/Carly 5200 Yusei/Leo 8000: "It's my move, so first I'll play my own field spell." Carly said. "I activate Future Visions. Now whenever any of us summon a monster it's removed from play until our team's next standby phase."

"Wait but why would you do that?" Leo asked in confusion.

"It doesn't matter why she played that card, it's far too late for her to stop us from wiping them out on my next turn." Yusei said coldly.

"We'll see, I summon Fortune Lady Light and then since it was removed from play I can activate her special ability and summon Fortune Lady Fire." Carly said. "That activates Fire's effect to destroy a monster on your field and…"

"And nothing, I play Stardust Dragon's special ability and sacrifice it to negate your Fortune Lady Fire's effect and destroy it." Yusei said as the purple glow around him increased in intensity. "Next I activate the second effect of Immortal Barrier by sending it to the graveyard I deal damage equal to Immortal Cosmic Dragon's attack points since a dragon type monster went to the graveyard."

"Not this time, I activate the effect of Adrenaline Spider." Roman said quickly. "By discarding this card I can negate the damage from your trap card."

"Wrong, as long as Immortal Cosmic Dragon is on the field you can't negate my trap card." Yusei said. "I warned you that you had one more turn and now you've lost."

"I set one card and end my move." Carly said nervously as Stardust Dragon reappeared on the field

Roman/Carly 2000 Yusei/Leo 8000: "In that case this duel is over, I switch Leo's Power Tool Dragon into attack mode, and then I'll attack with all three monsters." Yusei said coldly as Roman and Carly lost the last of their life points only for a faint glow to surround Carly as Roman faded into dust and two more purple marks flowed into Yusei. "Now for you Leo."

"What are you talking about Yusei?" Leo asked nervously.

"You take me for a fool you dared to try and destroy my Immortal Cosmic Dragon." Yusei said coldly as the Immortal Cosmic Dragon began glowing and a purple orb appeared in its mouth. "That mistake will cost you your life."

Just as Yusei said that, a blinding flash of crimson light enveloped the area before fading to reveal everyone except Yusei had vanished.

"What, where are we now?" Kalin asked in confusion.

"Well wherever we are, Yusei isn't here." Jack said calmly. "For that matter, neither is Roman."

"Of course not, he lost a shadow duel. Somehow even though we all lost too we were spared." Devack said. "It must be related to what happened to you at the end of the duel."

"You are correct Devack." said a voice from all around them.

"What was that?" Misty asked. "Who's there?"

"My apologies, but as long as you are here you won't be able to see my physical form." the voice said calmly. "I am the Crimson Dragon."

"The Crimson Dragon, but why are we here instead of Yusei?" Carly asked.

"She has a point, if you are the Crimson Dragon then why are we all here?" Kalin asked.

"So there's even a slim chance of saving the world." the Crimson Dragon said before the marks of the dark signers began glowing crimson.

"What are you doing to them?" Luna asked.

"The Immortal Cosmic Dragon is far too powerful for you signers to stop, especially now that it has completely corrupted one of your own." the Crimson Dragon said calmly.

"Corrupted, you mean when Yusei was absorbing that purple glow from the dark signers?" Akiza asked.

"Exactly, that's also why four of the former dark signers are with you." the Crimson Dragon said. "I managed to protect them from perishing after losing their shadow duels because it will take a combination of a signer and a dark signer to defeat Yusei Fudo now."

"Defeat him, wouldn't that cause him to die?" Kalin asked. "Especially if he loses to one of us."

"As he is now leaving Yusei alive is no longer an option. The fourth control tower wasn't sealed but doing so would have ensured the destruction of your world, the Netherworld, and the Spirit World." The Crimson Dragon said.

"Then what are you suggesting, he has all of the Earthbound Immortals in his deck and the Immortal Cosmic Dragon that he can summon." Jack said. "Taking him down will be nearly impossible."

"What's wrong Jack, are you afraid of him?" Kalin asked with a smirk. "So what if he has the Earthbound Immortals, Yusei and you managed to save me so it's only fair I return the favor and save him."

The moment Kalin said that, the four former dark signers duel discs began to glow crimson before their cards flashed.

"What just happened?" Misty asked as a faint purple glow appeared around them.

"Time is short, Yusei still possesses my mark and so I can only conceal your presence for a few moments more." the Crimson Dragon said faintly as the purple glow increased in intensity. "You must defeat Yusei Fudo no matter the cost."

"I'm so glad you all decided to rejoin me, now then where was I?" Yusei asked coldly before glancing at Leo. "Oh that's right, you tried to use that Morphtronic Self-Destruction System card to destroy my Immortal Cosmic Dragon, so now I'll let my dragon destroy you."

"Not this time, if you want to destroy any of us you'll have to beat us first." Jack said stepping in front of Leo. "Besides, it was my idea to destroy your dragon in the first place."

"That doesn't surprise me Jack, I had a feeling you were involved with that." Yusei said as his eyes began glowing purple and the dragon marking on his arm started to glow. "If you want to throw away your lives then go ahead, but it will be the last mistake you humans will ever make."

(Yusei and Leo managed to defeat Roman and Carly, but now Yusei is threatening everyone's life. Next chapter five individuals will make themselves known, and Yusei will undergo a transformation. As always any reviews or critique is appreciated.)
