Starting off with the rescue of Poppy but that was just it as Emu making his way seeing that Poppy was back to normal and Parado already mad

Emu: "Leave them alone!"

Parado: "Emu there's something you should know one thing...You are me. And Ray you and Fujikawa are one in the same." Then he turned into particles and possess Emu

Ray: "EMU!!!" Then they all went towards him "Emu!!!" This was when Ray got a punch to the face and him falling to the ground and this was when he takes out the gashat gear dual

Fujikawa: "What the?! Parado!!!"

Emu: "Henshin." He twist the dial to Knockout Fighter and press the button

Knockout Fighter! The strongest fist (Round 1)! Rock and Fire! The strongest fist (Round 1)! Rock and Fire! Dual up! Explosion hit! Knockout Fighter!

The Emu went to attack Ray but Fujikawa put up a barrier to stop him from attacking

Fujikawa: "GET OUT OF HERE!!!" They all nodded and run off

Emu: "Dam you..." Then he stops and his armor disappear and left

Later

Ray and the others (except Emu) were back at CR and were shocked what happened

Ray: "Guys did Parado...?" They nodded "Look we should-" Then he noticed that his driver his gone and all but one of his gashats were taken "Wait where's the other gashats?!"

Fujikawa: "And your driver! Dam it Emu must have taken it."

Ray: "Ok we should deal with that but first there's something I want to talk to you Fujikawa. When Parado said that him and Emu are one and the same and the same about us tell me is this true?"

Fujikawa: He sighs "Well then it's time for me to tell you about the day I was born."

Flashback

Author: "Hey guys this is your author Rgarciatiger/Tiger god. Now here's the backstory for the two (Ray and Fujikawa). It all started in the year 2000 and on that year it was when Y2K was at the time a thing for those who didn't know mostly millennials like myself when 2000 was about to come that was when technology was about to go down. Well it didn't happened but enough of that anyways on January 15, 2000 that was when Ray Rune was born but he wasn't born like normal people as when he was one year old his mother was gone not knowing how but it was due to her having the bugster virus. Basically it was Ray and his father and the two were somewhat ok as they never been seeing one another as Ray's father was working to provide for his son and was taken care by his aunt from his mother's side which he lived a regular life. When he was 9 his father gave him a gameboy color with Pokemon Red and then he started playing the game and was getting addicted towards video game (But no to where it's a problem) and started to play other games. At the age of 12 he started middle school at and early age but he wasn't feeling fine when he was at school. During one of his class he fell out of his chair and passed out. He was taken to the hospital and was positive for the bugster virus. Apparently the virus transmitted from someone in his family. Later one night we was bored as he doesn't have someone to play with so he started thinking of a player two/imaginary friend which he fell asleep and then the bugster (Fujikawa) was born knowing that he was born from him he couldn't let him know about his identity so he fled and was doing his stuff. Ray started to know about his father which he was a doctor and so it caught his interest. Later in his life he was in medical school and was doing alright."

End of flashback

Ray: "Well then I guess now I know how you were born."

Fujikawa: "Yeah but for now we should find Parado and Emu." They nodded and left CR

Meanwhile

Emu was alone and takes out the game driver and the Mighty Brothers XX gashat and press the button

Emu: "D~a~i~ Henshin." He inserts the gashat onto the driver and opens the lever which for some reason he was in his level X form which resulted in two Ex-Aid one was Emu and the other Parado

Gachan! Double Up! Ore ga Omae de! Omae ga Ore de! (We are!) Mighty! Mighty! Brothers (Hey!) Double X!

Gashacon key slasher!

Parado: He toss the key slasher to Emu "Emu fight me."

Emu: "What? No!" Then Parado went to fight Emu which he didn't even fight back and that was when Parado was stopped by a certain doctor, Ray

Parado: "What the?"

Ray: "STOP THIS!!!" Then he swung his hammer right at his face which Parado grabs it and then threw Ray to the ground and was about to use it but Emu use the key slasher to stop him

Fujikawa: "Parado stop this!"

Parado: "Why should I you and Poppy decided to sided with the humans!" Then he went to attack Fujikawa

Fujikawa: "Please just le-"

Fujikawa: "What...?"

Parado: "You heard me. You were just a bugster that had a weak mind."

Fujikawa: "Henshin!" He press the button on his gashat

Then he charges at Parado with full rage and this was when Emu takes out the Maximum Mighty X gashat and inserts it onto the key slasher

Maximum gashat! Kimewaza!

Then he charges at Parado

This then resulted in Parado to be reprogrammed with human DNA and Parado's armor disappears but this was a big mistake for them. As the other doctors Nico and Noire made it where they were Parado started laughing

Ray: "What's so funny? You lost, you're outnumbered."

Parado: "Idiots thanks to Emu I can use this." Then he takes out a game driver which it was Ryan's and puts it on "With this now my heart is starting to dance like crazy." Than he takes his gashat gear dual and inserts it onto the driver

Also true and dodges "Then you'll attempts to use the power of Perfect Puzzle and then I punch you in the face." That also happened "Next you'll say: How did you know you dam bastard?! Am I right?

Parado: He groans "How did you know you dam bastard?!" He gasp as Fujikawa summons his new weapon the gashacon kawa striker
