Last time on The Attack of Majin Buu, Blue and Echo Arrive to fight the Majin who had just absorb Asta.

Echo was the first one to fight and while he was winning, the Majin increased his power and started to overpower Echo....but then Blue steppes in, eager to fight as well

It was well even until Blue got distracted and almost lost if it weren't for Yami Sukehiro saving him.....

But the Majin saw this as an opportunity as he absorbed Yami, further increasing his power! Now dubbed Majin Buami, what will our heroes do? Find out now!

Blue: N-no way......it can't be!

Echo: Dammit!

Noelle: Ca-captain Yami!

Shinobu: Everyone get back!

Majin Buami: Finally! Now! Time to die!

He fires many ki blasts around the area as everyone dodges with Blue picking up Noelle who was still hurt and jumping away

Noelle: B-blue put me down!

Blue: Do you want to die?!

Noelle: N-no....

Blue: Good :)

Rengoku uses his flame breath style to defend everyone from the blasts as Echo helps by using his Gates of Darkness to warp the blasts back at him as it doesn't really do much

Buami: Let me try this....Dark Magic:......Dimension Slash!

He brings his hand down in a chopping motion as Rengoku barely blocks it, with some of the attacks catching his cheek

Rengoku: This power is too much! We're going to need more back up!

Blue: I have an idea! But first let's see if me and Echo can hold him off!

But before the two could attack him, Shinobu blocked an attack coming at them

Shinobu: Are you sure little brother?~

Blue: Yeah! I am! Let's go Echo!

Echo: Tch! Alright but you better not hold back! We're going full power at him!

Blue: Of course!

Blue and Echo transform into their Limit Breaker forms and dash at Buami who simply took their hits and then grabbed Blue and Echo as he smashes them together

Blue quickly kicked away at him whcich made him let go as Echo fired a Phantom Flash at the Majin at point blank range which did take off his head but was unfortunatly grew back

Blue: He just keeps regenerating! And we can't even stop it by completly destroying him! It's like we can't beat him!

Echo: Hey we can do it! We just have to beat him harder!

Blue: That.....could work but it has to be one hell of a beating

Echo: Yeah so let's hurry up!

The two try to rush him with their tag teaming abilities. How ever it was all useless with Majin Buami blasting Blue back and kneeing Echo in the stomach before slamming him back down and firing a Kamehameha down below him

Echo: Oh crap!

Echo quickly uses a Phantom Flash to slowly push the Kamehameha back at them. Blue recovers and uses a Limit Breaker Kamehameha from the side of the Majin as he quickly stopped his wave and dodged the two blasts

Blue: Damn so close!

Echo: Blue distract him!

Blue: You got a plan?

Echo: Yeah!

Blue goes to fight Buami with his Spirit Sword as it does pointless damage

Blue: Hey stop regenerating!

Buami: *grabs his head and brings it down to knee him in the forehead before kicking him back* No I don't think so!

Blue tries to defend himself but the Majin was slowly overpowering him as the others couldn't really do much...besides watch and recover their strength while hoping that whatever Echo is doing works

Echo: Almost there!

Shinobu: Hurry Echo! Before i punish you if my brother is dead!

Echo: Alright Sister Coplex midget!

Echo then catches the Majin by surprise as he charges his hands with shadow energy that surrounds Buami when he pushes his arms forward and hands opened up

Buami: What the hell is this?

Nero: It's...some sort of shroad of shadows

Echo: That is exactly what it is! My new move! Shroad of the Void!

The shadow energy enters the Majin as he screams in pain, confusing everyone and making Echo smirk

Blue: Woah what did you do?!

Echo: I'm invading his body!

Rengoku: Invading? *gasps* He's going to extract the the others out of him!

Mitsuri: He is?!

Nero: Not bad

Noelle: T-that means we can win!

Echo: Now....release them you walking bubble gum! Dumb dumb! Looking ass! The fuck up!

He closes his hands tightly and pushes them apart as everyone that got absorbed was released from the Majin's hold...Asta...Luck...Yuno...and Yami

Mitsuri and Nero with Rengoku's help catch them place them on the floor safely as they were all unconscious

Blue: Yosha! Nice one Echo! Now let's go beat him up!

It was shown that Majin Buu was back in his Buutenks form as he couldn't believe it

Majin Buu: No! No! No! You....bastard....I...Will..kill you!

Echo: Yeah right!

Majin Buu: AAAAAAAAH!

Blue: Calm down, it's gonna be alright! We're....

Echo: Just gonna send you to hell!

Majin Buu: No! It will be you who goes to hell!

Blue:.....But I have been a good boy.....

Shinobu: Blue please concentrate~

Blue: Fiiiiiiine

Everyone got ready but then Majin Buu let's out one final scream as his appearance changed, h was the same as before....except the clothes he was wearing was a Orange and Blue Gi

Rengoku: B-but he didn't absorb anyone else......what is this then?!

Mitsuri: He-he looks more scary!

Nero:.....I think....powerful is a more concerned term

Mitsuri:....R-right....

Buuhan: Ha! Ha Ha Ha Ha Ha Ha! Excellent! I'm stronger than I ever was before! Don't worry, the pain is momentarily....Death will follow!

He then does this pose which scared Noelle and Mitsuri

Noelle: B-Blue what do we do?!

Blue:....We could always.....r-

Shinobu: We're not running away~ ^_^

Blue: Oh ._.

Echo: Blue let's just fight him

Blue: Alright!

The two get ready as they try to do the same tactic as last time which involved double teaming and ki blast fire from the side which doesn't work as Buuhan regenerates his injuries and knocks the two back

He starts giving chase towards them as Blue and Echo fought back while escaping their pursuer as they flew by each other side while charging their attacks

Blue: Lets do this Echo!

Echo: Say no more!

Blue: Final Shine!

Echo: Amythest!

Blue/Echo: Attack!/Cannon!

Blue fires a Full Power Final Shine Attack as Echo uses his Amythest Cannon which was charged by the Red and blue pipes in his Shadow Limit Breaker Form as it fused to create a massive and powerful purple energy wave that Also fused with Blue's Final Shine Attack.

Rengoku: Amazing!

Mitsuri: Shinobu we should do that!

Shinobu: Hmm Maybe

Noelle: I want to do that with Mimosa!

Buuhan: Alright let's see...if you can survive this! Super Kamehame...HA!

He fires it at their combined attacks as it melts through it, catching them both by surprise

Blue: Ah crapbaskets....

The blast hits them both as Buuhan appears above them and does an over head kick that sends the two to the ground. He then lands on top of a house as he does these series of attacks

Start at 1:22

Mitsuri: B-B-Blue!

Rengoku: Ec-Echo! Dammit! Mitsuri! Lend me some support!

Mitsuri: R-right!

The two went to fight back at the Majin as Blue and Echo was still on the floor in pain after that barraged onslaught

Blue: Ow....I'm in r-real....p-pain....

Echo: Y-you....b-bloody sa-said it....

Shinobu: Blue why do you have to almost kill yourself every time you fight someone dangerous?~

Blue: I.....Don't know?

Shinobu: *Giggles* You're so adorable~

Blue: T-t-thanks!

Noelle: You're also a reckless Baka!

Blue: T-Thanks?

Nero: Anyways..Blue....didn't you say you have plan?

Echo: Yeah....m-mine didn't work....so what's your plan?

Blue gets up and helps Echo up as he has a look of determination on his face

Blue: Echo....do you know the Fusion dance?

Echo: Fusion Dance?

Nero: A dance? Wait I know about it!

Noelle: Y-you do?

Nero: I knew it about back when I was still learning with Lumiere, I read about it.....in a book

Blue: Just like me *rubs the top of her head*

Nero: *keeps a stoic face but blushes* Y-yeah

Blue: Alright.....Let me explain it

While Blue was explaining the Fusion Dance to Echo, Rengoku and Mitsuri were struggling against Buuhan

Buuhan: What's wrong?! Is that all you have to muster?! Against me! That's still nothing!

Rengoku: *pants* He is.....too s-strong!

Mitsuri: C-can we do this?

Just then Buuhan and the two pillars hear Blue talking about the Fusion Dance as Buuhan remembered what it was

Buuhan: So they have fusion here as well? Well looks like I will have to stop it!

He goes and attacks Blue but is stopped by Yami, Asta and Yuno

Blue: You guys!

Asta: Yo Blue! Hurry it up will you! Before me and Yuno steal all the glory!

Yuno: Yeah! It's out turn now!

Yami: Hey dumbasses....that's my line! *smirks*

The three attack him as Luck was still weakened, Rengoku helps them as Mitsrui rests

Luck: Awww I missed a lot!

Blue: Yeah you did

Echo: Hey hurry up!

Blue: R-right!

But then the four fighting the Majin were pushed back as Rengoku maintains his ground uses his ninth form as a last resort

Rengoku: You boys better have done this fusion by the time I use this! So hurry!

Blue: Say no more!

Echo: Don't have to tell us twice!

The two quickly rush back and get in position to perform the Fusion Dance, Rengoku uses all of his might to push back the Majin but it was inevitable for Buuhan to lose as he powers his way through the final attack of Rengoku and delivered a strong fist to his face, sending him back

Everyone prepares to fend off the Majin...but then they hear the two words that gave them hope....and the Majin Despair....

0:38

Blue/Echo: Fuuuuuusioooon......HAAAA!

The two re-enact the Fusion Dance perfectly on their first try due to the strong spiritual bond they have, a bright light appears and blinds everyone, once the light fades away....all everyone saw.....was a single being standing there.....menacingly

Buuhan: Who are...you?!

???: Me? Huh? Guess it's our turn to introduce ourselves.....we are the Fusion of Blue and Echo.......we are.......

BlueEcho!

Fusion at last! The two fighters have managed to successfully perform the Fusion Dance and create a warrior that far exceeded everyone's expectations....

BlueEcho! Will this new warrior manage go defeat the evil Majin? Or will Buuhan reign triumphant over the Fusion? Find out next time on The Attack of Majin Buu! Part 5! The Final Chapter!
