(location: the forest)

(A bunch of electric sparks start to form until a portal appears and a mysterious figure steps out)

???: So this is the future....
Good....my future might stop at a later time, but I can at least make my mark!

(The figure teleports off to somewhere else)

(Location: Gwain Castle)

Gwain: so, there are other worlds...

Iron: apparently so-

Guard: your majesty! We got trouble!

(A bunch of robots started attacking humans!)

(Gwain immediately calls Moon Tech)

Gwain: Luna, what is this?

Luna: (phone) this isn't my doing! Even my robots are going haywire, like they've been hacked with a virus.

Gwain: it can't be...

Iron: what is i-

Gwain: go see what is going on, all of you!

Iron,Deva,Agni,Baryl & Marlow: Roger!

(The 5 head out)

Gwain: it's not possible, he should be dead....

(Elsewhere in the city, the 5 arrive)

Iron(Zx): so much chaos....

Agni: who could have done this much damage...

???: Heh heh heh heh heh heh! So you're the defense of this era!

(A figure approaches them)

Iron(Zx): who are you?!

Model X(X): No way....

Model Cn(Colonel): Impossible!

???: Heh heh heh heh heh! I am SIGMA!

Agni(Fefnir): Impossible! You're supposed to be dead!

Sigma: wrong! Well not yet, In this era, I've already been wiped from existence, so I've decided to fix that error by making an impact on the present day!
Reploids, get them!!!

(A bunch of rogue reploids attack the Megamen!)

(Ignore Lumine)

(The 5 fight vigorously but to no avail!)

Iron(Zx): what are these things?!

Sigma: Yes! It's foolish! You cannot defeat m-

(A bunch of lasers hit Sigma!)

Sigma: ACK! WHO DARES!!

(5 mysterious vehicles start flying above them and 5 figures drop down from them!)

Iron(Zx): what the....

(The 5 figures land on the ground in front of the Megamen)

Sigma: who the hell are you?!

???: Mirai Sentai....

(All 5 of them make a pose!)

????: Timeranger!

Sigma: Time...ranger?

???: Sigma, you are in violation of the law, Time travel is strictly banned!

Sigma: you won't stop me, mavericks!
Annihilate them!

???: Beat-3!

(The red timeranger slashes through them)

Time red: You're going back to your era!

(Sigma's body goes limp)

Iron(Zx): what the?

???: You think I'm going back to 21XX?! NEVER!!!!

(A massive version of Sigma rises from below!)

Sigma: I'll crush you all!!!!

(The timerangers head into their vehicles and take off)

Time Red: 3-D formation! Alpha!

(The five vehicles form a giant robot!)

Time Red: complete! TIMEROBO α!

Sigma: wha-

(The robot slashes through the massive body of sigma, and sigma returns to his body unconscious and the huge sigma explodes)

Iron(Zx): what the?

(The five drop down)

Time Red: so, you're Iron.... Correct?

Iron(Zx) yes, but who are the 5 of you?

Time Red: well...

???: We might as well tell them, after today, they won't remember a thing of this.

(All 5 of them change into a more Human appearance)

Time Red?: Hikaru,Time Red.

???: Ryuji,Time Blue.

???: Kaoru, Time Green.

???: Yui,Time Pink.

???: Aria, Time Yellow.

Hikaru: there is one other, but he chose to stay behind.

Iron(Zx): so, why are yo-

Yui: we're of the Time Defense Bureau excluding Hikaru, dedicated to keeping the timeline in check.

Aria: Sigma traveled to your time to make an impact on the future, when someone time travels to another time without authorization, we're tasked with bringing them down, dragging them back to their proper era, and making sure they never remember what they done, but never attempt time traveling again.

(During this, Kaoru would be wiping Sigma's memory of his trip to Teora)

Iron(Zx): so, we won't remember this...

Aria: it's for the best.

(The five put on sunglasses)

Hikaru: say cheese.

(Hikaru uses a piece of equipment and with a bright flash, The timerangers,sigma, were gone)

Iron(Zx): why were we here again?

Agni(Fefnir): No idea...

(To be continued...)
