In the PowerPuff Girls Residence, the Professor is hard at work in his lab, mixing chemicals, studying artifacts and all that. He stops momentarily and check time which is already midnight which he got worried about his daughters but continues on his work to drown out the worry. His eye lids are constantly going down while he works but manages to shake off until a loud slam from upstairs made him wake up. He rushes upstairs and saw 5 of his children bruised and tired laying down on the broken down door. He rushes to them and assessed the injuries.

The 5 children are resting by the fire with bandages on their face and body. The children have different emotions on there faces ranging from anger to sadness. As one with black hair and green dress mope and mumble with her arms crossed and anger on her face. And orange haired girl in a pink dress is comforting a blonde girl in a blue dress, who was sobbing. Besides them is a big boned girl purple dress is depressingly looking down at the ground with tears on her eyes. And finally a tall teenage dark skin girl in a yellow dress is pacing in the middle frustration but choose not to show it infront them.

The Professor came to them with a tray of there favorite drinks and hands it to them gingerly. He puts it down on the table and sits on chair and asks them

"Girls, what happened?" He asked sadness

"The Rowdyruff Boys" Bliss answered in a calm manner but hold on to her anger "They were extra tough on this one"

"No they weren't" Buttercup she argued which earned her a angry glare from Bliss "You had to step up with your stupid legs i had Dumbo on my sights!"

This caused Bliss to lose her cool a bit as she argued back "Like you're no better, Your attacks was very sloppy and You were too busy checking him out"

Buttercup quickly flies up to Bliss and Both them argue for a solid minute until Blossom intervenes in the argument

"Stop! Were not goin-" before she could finish her sentence, Buttercup roughly pushed her aside and continues arguing with Bliss but this escalated as Blossom tackles and begin beat up each other.

The others sisters ex. Bubbles tries break them off of each and the Professor stood up from his chair, faces them, and deeply inhaled and lets it all out.

"ENOUGH!" He shouted in a harsh tone which caused all of them to stop.

The Professor regain his composure before talking again "Blossom, Buttercup two of are grounded. We'll talk about this later in the morning. Everyone, get ready for bed NOW" he said the last part with a stern tone.

They all went up stairs and went in the bathroom. The Professor sighs and heads back to the lab a cleans up his work.

After he cleans up his lab, he went to the Girls room which is very quiet, he gently opens it to see the Girls are fast asleep except for Bliss who is studying on the desk. The Professor smiled at her dedication and gently closes door.

Laying in his bed, The Professor is brainstorming idea on how to quell the arguments that been happening for pass years and help them with the villian that are getting more and more aggressive. Sure they had arguments now and then but when they grown older, they have become more violent that ever.

He rack his brain to find a solution as one idea keep floating around but keep shutting it down. I mean why need another child where 5 is already too many for one man. He sighs as he goes to sleep and thinks about this tomorrow.

--

The Next day, they discussed what and Bliss, Blossom, and Buttercup apologize to each other but there still grounded which they humbly accepted, some more so that the other. After they had their breakfast then headed for there schools, The Professor is ponder about the solution of there hierarchy issue. Thinking with all his might and experimenting on some mixture that can be ethical but gave in to the idea of having another child but having another girl would be devastating aka more girls, more headaches. He need to think of a balance.

He decides to make Boy this time which would be a huge gamble on how would girls treat him with all about the Rowdyruff Boys being there.

He slams his fist on his palm and decided to be solution that he would do but before he could do it, he goes upstairs and get a ice pack for his palm. Getting is old is not fun.

He checks his notes on the ingredients need for him create a boy which the girls told back when they defeated them for the first time. 'snips, n' snails, n' puppy-dog tails'

He nodded at the ingredients except for the puppy dog tail which made him queasy but he pushed that aside for bit gets all the ingredients prepared. First ,the armpit hair which was easy as he snip some his own. Second, snails are also quite easy as he grabs some on the his snail habits that he has. And lastly the most horrifying one is the dog tail. He went to the shady part of town and asked around to get a dog which they pointed him to a local rundown pound. He heads inside and He asked for puppy tails which the store unaturally giddy to accept as he head to the back with a creepy smile . Few minutes later the store owner is now cover in blood gave him a bloody paper bag which he uncomfortably accept and paid for. as he left, he barf on the near by trash can and tiredly head to his car and drive back home.

--

Back to his lab and prepares for the experiment. He grab a large pot puts in the ingredients and stir it. He carefully put in a right amount of Chemical X for one child. When he puts the amount, the pot violently shakes as he steps back and hid behind a strong wall and an explosion heard from the other side. He peeks behind the wall and saw a Little boy with brown hair and a midnight purple eyes amidst the smoke and purple outfit similar to the Rowdyruff Boys but his is much lighter in color and shorter sleeves, He sports a cap similar to Brick but Its facing forwards and a letter H on the middle of the cap. The little boy seems to be much smaller that his sisters when they were five and much more paler. He thinks to himself that the puppy dog tails from sick dogs may have caused this.

The Boy looks up to him with light purple eyes and an innocent smile as he looks around then back at the Professor.

"Hi, what's your name?" He asked politely

This takes Professor aback when he made the 4 girls but snaps out it immediately and tells him "O-Oh, apologies. My Name Professor Utonium and I'm the one who created you. Do you have a name?"

"i don't know since you're the one who created me then you can name me" he said in a innocent tone then flash a huge eyes-closed grin to him.

The Professor couldn't help be awestruck from his grin but he shakes it off and thinks of a possible name that starts in the letter B

A Light bulb popped up in his head and levels himself to the boy which he names "your name is Bix. Though i don't know why you have an H on your cap"

Bix giggles at his new name and he hugs his dad and the Professor accepts it wholeheartedly while he thought to himself

/i hope they gonna be okay with him. He seems slightly weaker that his sisters though. I must research further but for now/

"Alright, i should gets some essential for you and get ready for you meet your sisters" he said while still holding him

"Sisters?" Bix asked

"Yep, you have 5 of them" the Professor answered

This made Bix starry eyed and he gets excited to see his sisters. This made the Professor smile at his enthusiasm he lets him go but instead of him floating in air, he floats down slowly on to the ground which made Professor's concern all the more real of him being slightly weaker but he shoved those concerns for now and both of them head upstairs. The Professor told Bix to stay on the living room while he fix up the broom closet and Bix nods his head and starts exploring the house.

He wonders around the house and taking in the sight of the white paint and pictures of his supposed sisters, he tries flying up to the picture which he succeeds and takes a closer look.

--

Before his flight was cut short, he grabs the frame as he landed. He looks at the photo and looks at them with loving eyes and a loving smile. He hugs the photo frame and imagine all the fun he'll have with her sisters.

Suddenly a hand was place on his shoulder which surprised him and made him look to see the Professor overlooking him with a smile on his face.

"My, what little explorer you are." The Professor said in a calm voice

This made Bix embarrassed and made him look down to his feet and hands the frame to The Professor which confused Professor.

"I-i'm sorry, i just wanted see the house" he said in an apologetic tone

The Professor chuckled before telling him "Don't worry, i won't scold you for this." He reassured him as he remove his cap and ruffles Bix's hair which made him giggle.

"How about we explore the house together, okay?" He told Bix while putting the cap back on his head

Bix nods as he excitedly runs off and the Professor looks at him with smile on his face as he follows suit while holding the photo frame. The Professor show Bix around the house so he could get used to his surroundings and Bix listen to every word that the Professor said. Bix was ecstatic the amount of stories, collection of paintings and the size of the house. The tour led them into the Girls bedroom.

"And this is your sister's room." Said the Professor

"So I'm going sleep on the other room?" Bix asked

"Yep but I'll continue to fix up guest room for bit and it will be all yours"

"Really! Thanks Dad" he said as he run up to him and hugs his leg.

The Professor cooed at his affection as he pets his head and Bix release his leg.

"Tell me dad, what are my sisters like?" He inquired

"Well like i said you have five" said the Professor and flips it infront of him and points out as he goes "First, the oldest name is Bliss is the one in the yellow dress. She is caring and motherly but her power can be unstable if she stresses too much. Next the pink one is named Blossom, shes' the leader of the Powerpuff Girls. She is a smart and clever girl but she can be stubborn at times, The one with blue dress is named Bubbles, she sweet and sensitive but she can fairly dangerous when gets angry. The green one is named Buttercup, she the toughest fighter of group but can be overconfident in her abilities. And last the same as your color is named Bunny, she's a strong and energetic but she can be impatient. And all of them are known as the Powerpuff Girls"

"PowerPuff Girls?" Bix asked "An Odd name, Why are they called that?"

"Well that's there Superhero name" he answers "Townsville is filled with villains and evildoers that are constantly destroying the peace and that's where your sister defend the city to keep it safe."

"Woah! That so cool! Are they doing it now?" He asked excitedly

"No, they're at school but sometimes when duty call, they answer" he answers"That reminds, i have to prepare for your enrollment in school"

"What's a School? Is that a villain?" He asked

"No Bix, it's where you come to learn that equips you with knowledge that is needed in the future."

"Really? That sounds useful" Bix said

"It sure is" said the Professor. A loud thud as something fast flew in that came from the door.

"That must be them" said the Professor. Bix followed as he walked down the stairs. The Professor motioned him to hide behind the plants and keep quiet.

--

The Professor sees all the girls doing there own thing while they talk about girl stuff. The Professor is relived at the patched up relationship of girls.

"Hello, Girls" he greets them which caught there attention.

"Hi Professor!" They all responded happily

"I see that you're all doing well, how was school?"

"Aw Professor, you should've seen Buttercup when she was playing Dodgeball in school. She was like, bang, paw, bwaa, boomchikalaka." Bubble expressed excitedly as she explained to what happened in Gym class.

Blossom puts over her hand onto Bubbles mouth to make her stop but she didn't which Blossom just drags her away

"It was nothing special really happen, except a fire broke out and the school had a day off so i just went to the mall." Bliss said nonchalantly which the Professor looked at her with confusion

"Why didn't you do anything?" He asked curiously

"The teacher would put me in detention if i use my powers again. It not my fault that Sir Brandon was acting being mugged in a random parking lot with a acting burglar."

The Professor let out an exasperated chuckled as Bliss goes back to reading her book. Bunny has fallen asleep on the couch and Professor thought her practice is intense when in reality she stayed up watch all night a copious amount of teledramas. He gently woke her up and she stirred awake.

"Bunny, wake up now. I have a surprise for all you" he said which made her burst up with energy and everyone took notice as they gather around the Professor.

"A surprise?" Bunny asked

"Yes dear. Everyone close your eyes and don't try to peek, okay?" He asked them to which they all nodded and closed there eyes

Bubbles tries to sneak one but Professor noticed and he glared at her, making Bubbles close her eyes back.

The Professor beckons Bix to comes closer and he hurry to the Professor with few trips from being so excited and nervous to meet them all.

He puts Bix infront him with hands on shoulder then asked them "Alright, open your eyes"

They all open up there eyes and they gasp to kid a in front similar to them but smaller that the trio when they were five

"This is your new brother, his name is Bix" The Professor said with a welcoming tone

The Girls look at Bix with mix emotions. Blossom is very Interested and suspicious at Bix. Buttercup is angry at another addition and it's a boy this time. Bubbles look at him with happiness. Bliss gets all giddy for another sibling to take care of. And Bunny is excited for a boy to train with.

Bliss zips up to Bix and starts hugging him like a mother hugging her child then tears of joy starts leaking out of Bliss's eyes as she hugs him, lovingly.

"Oh happy days! Another sibling to take of and spoil" she said as she rocks Bix "Though he is smaller that the trio when they were younger but than makes him even more cuter" she continued as she tickles Bix, making him giggle.

Bubbles then came up to Bliss and taps her shoulder.

"Can i hold him?" Asked Bubbles

Bliss nodded and pass Bix to Bubbles which surprised Bubbles on how small he is. Bubbles stares at the little boy on her arms and she starts tearing up from the sight.

This surprised and confused and even anger some on everyone in the room. Bliss places her hand stub on Bubbles shoulder.

"is something wrong Bubbles?" Bliss asked in worry but Bubbles couldn't respond to her and just kept to tearing up. Blossom and Buttercup flies to Bubbles while Bliss told to Bix to grab a box of tissues which he complied hops off of Bubbles arms.

The Professor starts comforting her by embracing her and rubbing her back. He felt a light tap on his ankle and look to see Bix holding a box of tissues. He grabs one and wipe the tears of Bubbles.

"It's okay, Bubbles. Tell us why were you crying?" He asked

"I-i wish i could Professor but i don't know why too" she said in a shaky voice. "I just started cry when I hold on to him"

"Maybe you're just excited that couldn't hold back." He commented as he pulled away "it's highly possible"

"How about we eat dinner to calm down, okay? I made your favorite" The Professor said with a smile on his face which help Bubbles calm down

"Okay Professor" Bubbles agreed

Everyone nodded in response while the two puffs are giving Bix the stink eye but his oblivious to it.

--

After they cleaned up, the girls sits on there respective seats except for Bix who is just standing and looking confuse.

"Where can I sit?" He asked

/On the floor/ Buttercup thought bitterly

"How about with me?" Bliss suggest "of course, you could just ask the Professor to-"

Bliss was interrupted by Bix trying to hop up to her lap but her seat is higher that her sister with the exception of Bunny.

Bliss awed to his cute attempt to hop up to her. She scoops him up mid jump and gingerly places him on her lap.

"Well aren't you a little go getter" she cooed as she ruffles his head which caused him to giggles.

Then the Professor comes into the room with a tray of food and sets it down on the table.

"Sorry for the inconvenience Bix. I didn't have time to get you own seat." He apologized

"It's fine Dad" said Bix "I like sitting on big sis's lap"

Bliss awed of Bix's words and she hugs him tightly like a teddy bear which caused Bix to suffocate as he tries to resist but he wasn't strong enough to push even her hand

"Bliss, you're hurting him" he points out

Bliss realize this as she lets him go and rubs his back. "I'm sorry, are you okay?"

After a few breaths, he nodded in response and Bliss sighed in relief and she opted to pat his head.

--

After that little episode, they said their thanks to the Professor and they eat their food while Bix is being spoon fed by Bliss because he can't reach the table. Buttercup and Blossom look at him with suspicion as they eat their food respectively. Blossom finish her food first and she immediately cleans her plate and flies off. Butter also did the same except for cleaning the plate and Bunny just up and lef to go outside and go do some some night jogging. The Professor sigh of the two just left there plates in a hurry but didn't pay much attention to it. After the 4 finish there eating, The Professor place all the plates in a stack and the utensils on top of the plates and heads back into the kitchen. Bliss picks him up and both of them heads off to the bathroom with Bubbles following.

In the bathroom, Bliss and Bubbles are in the bathroom tube relaxing while Bix seems scared of the unknown water. Bliss giggles at his fear and she carefully drags him into the water which resist but quickly adapts to the water and relaxed. After the bath, they dried off the excess water and head to the sink. She picks him up to the sink and she picks her tooth brush and puts little bit of toothpaste on it and asked Bix to show his teeth.

Bix complied and parts his lips as wide as he can and Bliss starts brushing his teeth. She stops it then motions him to spit it on the sink which he complied.

"I'll do this for now so that you know how but you'll have to do it by yourself later on okay? " She said

Bix nodded as she hands him the toothbrush and starts brushing while Bliss grabs another spare brush and brush hers.

--

After that whole hygiene routine, Bix is in his bed, staring at the ceiling with a smile on his face.

/This is so cool. I can't wait to be a superhero with my sisters, though I feel something bad about Blossom and Buttercup but I'm sure they'll warm up to me/

And with that, Bix drifts off to sleep with a future ahead of him.
