The 4 teams went to a highway were screaming was occurring. Gin Amis was leading many foot soldiers.

Amu recognised him

Amu (pointing at him): That's the figure that attacked me.

Gin Amis: Anyone else recognise me.

They noticed his looks

Yamato: Ginis?

Lucky: Don Armage?

Gin Amis: No. A mixture of them, call me... Gin Amis

Spada: Hand over that collection thing!

Kotaro: Yeah! We need that to get home!

Gin Amis: Don't you see? I gathered you all up, so I can destroy you... all... at... once.

Stinger: Let's see you try that.

LupinRangers and Daiki: KAITOU CHANGE!

PatRangers: KEISATSU CHANGE!

KyuRangers (minus Shou): STAR CHANGE

Shou: GARYOU TENSEI!

Zyuohgers: WILD INSTINCT, AWAKEN!I

Everyone started charging at fought bravely

Umika tried to take a stab at Gin, but then

Gin grabbed her sword and said

Gin: I know of youre past LupinYellow.

Umika: What?

Gin: I know of youre friend Shiho.

Umika (keeping herself from crying): You don't know anything!

Gin: If you did something, she would be alive today

Umika was getting depressed

Gin: She probably hates you in the afterlife right. YOU DONT DESERVE ANYONE!

Umika then dropped her sword and cried through her helmet

Gin kicked her and her helmet came off

Umika started crying on her knees.

Amu was getting furious at Gin

Gin: Youre nothing but a poor friend for letting her down.

Gin was about slash her apart when Amu, in her Instinct Awaken Mode, ran up to him a tried to slice him

Amu: STOP IT NOW!

But Gin grabbed her fists and twisted them hard

Amu let out a enormous shriek

Gin: This will be another example.

Gin then charged his saber, and in when slash, made Amu shriek harder then she ever had

Amu feel to the ground and de-transformed

All her allies where in shock, especially Umika

Everyone: AMU!

But Gin pushed them and Umika back and made a force field so they couldn't stop him.

Gin: I will show you youre punishment.

He stomped hard on Amu's arm, making her yell. Then he grew tentacles and with a touch, made a terrible, but unknown, thing happen to Amu as she screamed more and she screamed every time Gin made her bleed or such until she passed out

Everyone begged him to stop, but he kept on going

Umika: STOP IT!

And when he was about to fatally stab her in the heart, Gin was shot from above

Gin: WHO'S THERE?

Sela (pointing up): LOOK!

Everyone saw a strange figure in red

(AN: He has the voice of Tetsu from DekaRanger. PS, He's the new special sentai)

Red figure: Can't have you go doing that.

Gin: And who are you?!

Red figure: You can call me... Mugen Red

Gin: Mugen Red?

Mugen Red: I'm going all out.

Mugen Red jumped right on to the ground and engaged Gin in a slashing fight

He also made his own force field to protect Amu

Gin thought he could take this new red senshi, but he was actually skilled

Gin: Can you take these then?

He summoned many Moebas, Invaders and PonderMen

Mugen Red: Well, my TEAM can. Time to show you what Mugen is for.

He took a small sphere, pressed a button on the top, and placed on the center of his chest

Mugen Red: MUGEN SWAP!

A series of flashing lights occured, after they were finished, Mugen Red was now in... blue?

(AN: This voice is Momotaros from Kamen Rider Den-O)

Mugen Blue: I am (crazilly) MUGEN BLUE!

Mugen Blue went wild on the enemies, he tossed them around, hitbthem hard, and even a few wrestling moves

He used the sphere again

Mugen Blue: MUGEN SWAP!

Now in Purple

Mugen Purple: MUGEN PURPLE!

He shot plenty down and switched again

Now he appeared as... a woman?

Women: MUGEN PINK!

More fighting continued as he/she went through 10 forms

Mugen Red (Male)

Mugen Blue (Male)

Mugen Purple (Male)

Mugen Pink (FeMale)

Mugen Green (FeMale)

Mugen Gold (Male)

Mugen Black (FeMale)

Mugen White (FeMale)

Mugen Brown (Male)

Mugen Orange (FeMale)

After a whole switch, he was back to Mugen Red and all of them were defeated

Gin: Who are you, and how do you do that?

Mugen Red: Thanks to this sphere, I can switch between different lifeforms inside to increase in strength. Together we are, GATTAI SENTAI MUGENGER!

Other Sentai: Mugenger?

Gin: I'll destroy you all soon, enjoy youre friend.

And with that, he teleported away.

Mugen Red carried Amu over to the others.

Bud: Thank you, Mugen Red.

Mugen Red: No prob. You need to help her though, whatever that thing did.

Mugen Red then left

Keiichiro: Back to the infirmary! There has to be a way to help her.

(AN: So what do you guys think of the idea of Mugenger, do you think that will happen after LupinRanger VS PatRanger, or something else)
