Beat was having a conversation with his Wife Note,it was going pretty good and then they see Jammy and Kitty which made Beat more happy to see them again

Beat:Guys good to see you again!

Jammy bonk Beat on the head

Jammy:Heh i get that you are married but you could have texted us!

Kitty would have a slight smirk on her face

Kitty:Hun? Do you miss our little brother that much~

Jammy would have embarrassed look on his face

Jammy:No shut up!

The three of us would giggle as this and makes Beat very happy

Beat:Hehe it is quite the surprise how much the world has changed huh?

Note:Very true hun so how is Heroes?

Kitty:Oh he is doing good,he is currently married to his version of girls

Beat:Heh good for him wait what about Jordan and Shadow?

Jammy:Heh those two were taking a vacation with their harem to relax and breathe after the whole "Time War Incident"

Beat:Yeah...

Beat would feel his hand shaking like he was afraid of something this got Kitty and Note concerned 

Kitty:Hey bro are you ok?

Note:Yeah are you ok hun?

Beat shake his head and holds his shaking hand

Beat:Y-Yeah i'm fine

Jammy:Are you sure? it looks like you are scared of something after that war,was it Sea-

Beat:NO! i-i'm fine,i'm fine

The area was silent and this was surprised Jammy and Kitty,they never seen Beat this emotional or scared before,Jammy knews that Beat can be idiot,a dumbass and a tough fighter and strong and cool bro but Scared?? something was not right at all

Beat:B-Besides that how is Nintega doing by the way,is he you know?

Jammy:Hehe that chaotic idiot is still being his silly self but besides that he is married to Mona,Eula and many of his girls and living a good life.

Beat:Heh i'm glad

They begin to talk about their Adventures until they would get a alarm about timeline being corrupted by Fu again

Beat:Alright let's move Team!

Jammy:heh who  made you boss?

Beat:No funny business let's go!

Note:I better get back to the house making sure that everything is ok with our baby

Kitty:Yeah i can't wait until Little Beat comes out

Jammy:Let's hope he doesn't have Beat's stupidity 

Kitty:Hehe yeah but Hun can we talk about Beat for a sec there when we get there

Jammy:Yeah i want to talk about it too let's talk about when we get the anomaly

Kitty would nod in agreement because they can tell that Beat was not acting like himself,Beat,Jammy and Kitty would arrive in Age 767 where SSJ2 (Youth) Gohan fights Perfect Cell but he was not alone,Majin Buu would arrive on the scene to kill Gohan and Cell but Beat would arrive in his SSj4 form and kicked Buu towards a wasteland where they can fight all out

Buu:You fight good but Buu is better

Beat:Die you piece of shit!

Jammy and Kitty would arrive on the scene to help but See Beat beating Majin Buu to bloody pulp and Beat finished him off without a problem but Beat was not satisfied with his death and sees Fu above disappointed

Fu:Awww man this was no fun that's it no more crystal food for- AGH!!

Beat:SHUT YOUR FUCKING MOUTH YOU WORTHLESS DEMON! 

Beat starts to choke on Fu with his hands and was not stopping killing this Demon but hears the supreme kai of time telling him to stand down and not to kill him but Beat doesn't listen and chokes him harder and harder but Fu gets away which enrages Beat and screams Fu's name with such Venom in his tone

Jammy:Hey we fixed the cell mess while you holded majin bu-

Beat:where have you been bro?? have you been messing around again?! OR DID YOU FAIL LIKE EVERY SINGLE MISSION!

Jammy:Dude we just clear a mission i don't know what are you talking about!

Beat:DON'T LIE TO ME!!!!! 

Jammy dodges his attacks while trying to calm Beat down since Beat is filled with Rage and Sorrow in his eyes

Jammy:Bro listen to me,this is not you,you need to calm down and relax,me and kitty dealt with anomaly problem,it's over just relax

Beat:SHUT UP,SHUT UP!!! YOU RUINED MY LIFE,YOU RUINED EVERYTHING!!!

Beat doesn't listen to Jammy and starts to roar enraged and attacks with rage in his eyes which surprised Jammy makes him use his Ultimate Form

Jammy:Bro tell me what's going on?! what is this about?

Beat:YOU RUINED MY LIFE SEALAS,I WILL DESTROY SINGLE FUCKING ATOM IN YOUR DAMN  BODY!

Jammy:Sealas? No he thinks i'm sealas but why?

Beat:RAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH!!!!!

Jammy dodges and counters my attacks but Suddenly a burst of dark ki starts to surge within Beat and combine with the Primal Ki of Super Saiyan 4 would change him into raging beast,the form would have darker fur all around it's body and it's feet is like great ape but the eyes were raging red and Beat has a new form Called Berserk Super Saiyan 4 (ベルセルク超サイヤ人4)

Jammy:Well this is not gonna be easy 

Jammy and Beat begin to fight and Jammy has the advantage in the fight but Beat starts to bite Jammy's arm which annoyed Jammy and kicked Beat in the face and sledgehammer him into the ground

Jammy:This guy is tough,i need to find a way to stop him but how?

Kitty:Maybe i can help 

Kitty screams more and powers up into her Beast form

Jammy:Ready Hun?

Kitty:Always!

Beat:GRRRRRRRR RAHHHHHHHHHHHHH!!!

Jammy and Kitty would nod at each other and charges at Beat hitting him with punch combos and kick combos which annoyed Beat but damaged him however the rage begins to consume and shoots many,many ki blasts around the area which would catch the attention of Beat's Young Uncle Gohan

(Youth) Gohan:Need some help?

Kitty:Yeah can you distract Beat for us? me and hun have a plan!

(Youth) Gohan:GOT IT 

Gohan brings to distract Beat with ki blasts and kamehamehas at Raging Beast however the beast grabs gohan by the neck and drags his face into the ground and punches him more and more and more until Gohan was knocked out unconscious 

Beat:RAHHHHHHHHHHHHHHH!!!!!

Jammy:HEY BRO!!!!

Beat would turn around to see Jammy and Kitty charging up their own attacks and ready to fire at beat but the beast doesn't care and charges up more and more and more bigger ball of energy in his mouth and shoots it at Jammy and Kitty

Kitty:Alright Hun it's now or never!

Jammy:Right!

J&K:SPECIAL GODLY CANNON!!!!!!!!  (特製神砲)

Two beam clash with each other and create massive shockwave around the earth meanwhile with Jammy and Kitty are using everything they got to stop Beat's Rampage but someone else joins in on the party that being Gohan,Kitty and Jammy nodded and closes their eyes and clear their minds and retaining clarity of thoughts and emotions and finally used Ultra Instinct at short burst

Kitty:FULL-

G&J:POWER!!!!!!!!!!!!!

The beam would grow bigger and consume Beat's blast and making contact with beat hurting very,very badly but doesn't kill him just make him unconscious and finally the battle was over,Jammy and Kitty were exhausted from using ultra instinct even though they used for just a second,the two look at each other and kiss making Jammy smirk

Jammy:Nice work Hun~

Kitty:hehe thanks hun now let's get back home

Kitty looks back at Beat's unconscious body with worried and concerned face

Jammy:Yeah we need to find out what the hell is going on with Beat,i never seen him so fearful

Kitty and Jammy would fix the Anomly in the Cell Saga and head back to Time Nest with very,very concerned Supreme Kai of Time running over to Beat's side

Chronoa:What happened?

Jammy:that's the thing we don't know,Beat was fighting against Buu but killed him without any remorse but not only that,He was about to kill Fu

Chronoa:What?!

Kitty:That's not all,Beat was in this Dark Super Saiyan 4 form,we think Beat is hiding something from us and acting like everything is ok

Chronoa:Beat...

Jammy:Hey can you take us to Beat's Mindscape?

Chronoa:I mean i can try but it's been a long time since we have to deal with this,are you sure you two are up for this?

Jammy:You bet! i need my idiot brother back.

Kitty:Same here!

The kai of time nodded

Chronoa:Ok head back home,i can tell that this is something old from Beat's past

Kitty:But what could it be?

The silent filled the room until Jammy answered

Jammy:Sealas,He was former time patroller that tried to destroy the time nest but was defeated by Beat's Blue form and SSJ4 Xeno Gogeta but why would he think about him?

Chronoa:I don't know why but you two get some good rest,i have a feeling Beat is dealing with real opponent he couldn't beat,HIMSELF

Beat:Please make it stop,it hurts,It Hurts so bad PLEASE MAKE IT STOP!
