Ok so this was suppose to be in my Idea Book but I started it at 12am at midnight, so I accidentally put it here instead. When I try to find fanfics about Underfell Papyton and their child Trajan, most is Papyrus being abusive. I get it that he would pressure him, but not being straight up evil. But that's only my opinion. I do not own Undertale and the AU Underfell, as well as the characters Trajan and Don. They belong to their respective owners.

This will also involve my headcannon that a monster's soul will become the color of the trait they represent most in their life. Here are what the characters soul traits will be.
Frisk- Determination
Chara- Determination
Asriel- Love
Monster Kid- Bravery
Toriel- Perseverance
Asgore- Justice
Papyrus- Bravery
Mettaton- Perseverance
Napstablook- Patience
Sans- Integrity
Alphys- Justice
Undyne- Determination/Kindness
Don- Patience
Kip- Justice
Mad Dummy- Justice
Dummy- Kindness
Shyren- Patience

I imagine that since Trajan wants to be different, he would try to be nicer than the monsters in the underground. Don is a Alphyne child who is cousins with Trajan. Kip is a Nicepants child. Like Impact, I think Trajan and Kip would have a friendship, like Impact with his Kip *wink*. It's after the Pacifist ending. Chara and Asriel were brought back. Also the Dreamurrs are good friends with them.

Frisk, Chara, Asriel, Monster Kid and Trajan are the same age. I like to think that Chara and Asriel were 14 when they died, and Trajan is the youngest. Don and Kip are 2 years older than them.

So many ships.

'thoughts' "speech" *actions* flashback

================================

Tomorrow will be Trajan's 14th Birthday, as well as Christmas.

A monster's 14th birthday is a very special event, like a humans sweet 16th. It's the day that their soul will no longer be white. Everyone got excited for Trajan, even his dad, so they began to plan a party for him. So Trajan's family and friends, as well as the Dreamurr family were at Grillbys.

Sans, Don, Napstablook, and Mettaton don't really care what his soul trait will be but is still excited for him. Papyrus, Alphys and Undyne are betting what soul trait he'll get in one of the booths. Everyone else was just waiting for the party and scattered around Grillby's since there weren't that many people.

P: "OF COURSE HE WILL GET BRAVERY!!"

U:"No way! Trajan is strong! He will get Determination!" *punches the table and made a small crack on it*

A:"U-Undyne, Don't break the table! A-Also, m-maybe he w-will get Kindn-"

P:"THERES NO WAY MY SON WILL GET SUCH A WEAK TRAIT!"

U:"What makes you think Kindness is weak!!?"

P:"THERE ARE- UNDYNE LET ME GO!" *gets carried by Undyne*

Undyne then suplexed Papyrus while Alphys sighs at the booth she was sitting at. Mettaton, Mad Dummy, Dummy, Shyren and Napstablook were talking about the activities and music they will play. They were all actually talking calmly. Probably for Mettaton and Napstablook's friend and musical worker, Shyren.

M:"-then we can have couples dance together! Napstablook, you can dance with Shyren-"

N:*Blushes* "She's not my girlfriend!*

M:"I didn't say that, I just needed two people to dance first to get it started"

M.D.: "Don't your have a crush on-?"

N:"Shut up!"

D: "your blushing~"

N:"IM NOT!"

Then they began to argue. Shyren's cheeks shows a tiny bit of a blush.

Sans was talking with Toriel and Asgore at the bar stand. Toriel and Asgore decided to be friends at least. Frisk, Chara, Trajan, and Asriel were talking at one of the tables and informing Frisk about what it is.

F:"So If monster souls do become a color when they get older, why were most of the monsters I fought had white souls?"

C:"Well white can also represent the trait hope, and most monsters in the underground were hopeful of getting to the surface."

F:"But aren't monster souls usually made of Hope and Love?"

C:"Yes. But if a monster represents the traits Hope or Love the most, it will stay white or become the color of Love."

F:"Ok. So if a monster hardly loves or hopes for something or someone, they're soul will either die, become corrupted, or just become a different soul trait if they show something else besides Hope and Love."

T:*nods* "That's about it. When Asirel and Chara died, monsters either became corrupted or their souls became the trait of Hope. When you came, you were able to SAVE those souls, like my Mom and Dad." *drinks his soda*

F:"Wow, thats amazing. So what's Asriel's soul trait?"

A:*crosses arms* "That's for me to know and for you to-"

C:"It's pink, so it's the trait of Love."

A:*glares at Chara* "What the hell Chara! You promised me you wouldn't say anything about it!"

F:*smiles*"Aww~, that's so sweet"

T:*stops drinking their soda and laughs* "Holy s**t that so hilarious. But it makes so much sense."

C:*giggles* "Yeah. Azzy may try to act all tough, but he's pretty much a softy"

A:*groans and hides their face in his arms that are on the table* "I hate you all...."

C:"C'mon Azzy, we all know that you LOVE us"

A:*groans louder* "Those are even worse than Sans"

T:"No, just no."

Kip and Don were just watching everyone doing their thing. Those two were also at one of the booths, they were drinking smoothies.

D:"So...."

K:*looks at him weirdly* "What?"

D:"You know..." *points his finger to the table  where Chara, Trajan, Frisk, and Asriel are*

K:*looks at them, then back at Don* "What about them?"

D:*points to Trajan specifically and then at Kip*

K:*getting annoyed* "What the f**k is it?!"

D:"You and Tray!"

K:"So?!"

D:*deadpanned look* "Dude. D u d e. You love him."

K:*pauses, then blushes* "w-what makes you think that?!"

D:"Hmmmm, let's see..."

Flashback #1.....

Trajan's friends and his cousin Don were at the MTT Restaurant. His mom wanted him to perform something.

They were all talking until they see Trajan on the stage. He haves his Saxophone, then he started to play a combination of Death by Glamor and Bonetrousle. Everyone at the restaurant started to cheer and whistle, including his friends and Don. Don looked at Kip to see he haves a love struck expression.

Flashback #2.....

Papyrus and Undyne trained Asriel, Chara, Frisk, Monster Kid, and Trajan for 6 hours in a forest. Now they had the rest of the day off. Kip and Don were watching the whole thing.
They all decided to go to a nearby ice cream place. Kip saw Trajan still sitting on a rock and seems to try to stand. So Kip decided to approach him.

K:*smirks* "What? Can't stand?"

T:"Shut up you bastard, of course I can stand"
*tries to stand up again but fails* *blushes a little in embarrassment*

K: *rolls his eyes* "uh-huh, of course you can"

Out of nowhere, Kip put him on his back piggyback style.

T:"What the hell?! Put me down now!"

K:"Yeah....no"

Trajan just sighs and plays with Kip's hair out of boredom. If Trajan was looking at Kip's face, he could see he is blushing.

Flashback #3.....

Last night Trajan lost to a bet and now he haves to wear a dress for the whole day. His Momatton chose the dress he will wear.

(Imagine it red, Trajan is also still wearing his boots and gloves)

He's at the mall with Kip because he promised him they would hang out that day. The two are at the food court. Kip ordered some burgers and fries while Trajan ordered some ramen.
For some reason, Kip kept staring at Trajan.

Then a dog monster guy approached the two at the table.

Monster dog: "Hello there~, and who might you be?"

Trajan: *confused* "Hi? I'm Trajan"

Monster Dog:"Hello Trajan, can you come with me for a sec. Somewhere private~?"

Trajan:"Hmmm, how about you f**k off?" *left eyes start to glow red and yellow*

Monster Dog:*raise hands in defense and surprise* "Woah, don't worry doll face, I don't bite."

Kip:"I do" *drags monster away to a very private place where there are no cameras at*

A few minutes later, Kip comes back.

Flashbacks end...

Don is looking at Kip with a smirk.

K:"How DID you know about what happened at the mall?"

D:"Tray told me, so I assumed what happened next. So you have a thing for my cousin?"

K:*sighs* "Yes. I'm hopelessly in love."

Suddenly Chara, Asriel, and Frisk joined them in the booth. Trajan went home early.

C:"So you DO love him" *wiggles eyebrow*

F:"My Otp is true!" *fangirls/fanboys in excitement*

A:"It was obvious, but not as obvious as Frisk and Monster Teen"

Everyone jokingly laughed at that while Frisk looked down and blushed. Kip stopped and looks at his beer sadly.

K:"To bad Tray is straight"

Everyone at the booth became silent and stared at Kip in surprise. He looked up at them, then they all began to laugh at him.

K:"What's so funny!?"

A:*laughing* "He's gay!"

C:"Gayer for you than Sans is for Grillby!"

F:*laughing so hard they are holding their stomach and banging their hand on the table*

K: "How would any of you know?"

F:"Well....."

Flashback #4.....

Frisk is at Trajan's House in his room. They were both laying on his bed watching anime on his computer.

T:"Frisk?"

F:"yeah?"

T:"Have you ever looked at a guy and thought, d**n he's hot?"

Frisk stopped looking at the screen and stared at Trajan.

T:"I guess it's nothing"

F:"Y-yeah, probably..." 'Chara WAS right! He's gay'

Flashback end.....

K:*wide eyed with their mouth open in shock*

D:"Yep. Even his parents knew when he was 8"

Flashback #5.....

Papyrus brought Trajan and Don to the park playground in the Capital. When he went to get them a snack, Don was playing in the playground but Trajan was gone. So Papyrus started to look for him.

Papyrus:*approaches a monster* "HAVE YOU SEEN MY SON? HES A SKELETON GHOST HYBRID, BLACK HAIR, FOUR EYES, AND CLEARLY GAY BUT WE HAVEN'T HAD THE TALK YET"

Flashback end....

Everyone stared at Don in complete silence.

D:"Yes that was what actually happened"

Then they all laughed so loud everyone there were staring at them in confusion.

=Time slip brought by the ship Underfell Papyton=

Its 1pm on Christmas and it was only 2 hours before Trajan's soul trait will appear. They did bunch of things like the most epic snowball game. Teams were...

Dreemurrs-Asgore, Toriel, Asriel, Chara,

Royals- Undyne, Alphys, Don,

Ghost- Mad Dummy, Dummy, Napstablook, Shyren

Teens- Monster Teen, Frisk, Kip,

Skeleton- Papyrus, Sans, Mettaton, Trajan,

After only 10 minutes into the game, it became an all out war zone. Everyone was using their magic. They somehow made the snow like their magic attacks.

When a hour has passed, it was a tie for all teams. So they went inside for food and drinks, and just talk. Alphys got Undyne to secretly put some mistletoe. Monster Teen and Frisk kissed. Trajan was just talking to Kip.

K:"wait-wait-wait, they did WHAT?"

T:"They both were trying to get street money in the same place, so they challenged each other to a saxophone off for 3 hours. Then a little girl came and played the violin. She then said Leave it to the professionals"

K:"Holy heck that's so random"

They both laughed at Trajan's story. Kip noticed something above them.

It was a mistletoe.

Eventually Trajan noticed it too.

A:*comes up behind them* "Just f**k each other already?!"

They did not take it well.

T:"Asriel wtf?!"

K:"Seriously?!"

M.T.:"If your going to the Bonezone, do it in a room"

F and C:*chanting* "Kiss! Kiss! Kiss!"

T:"IM GOING TO JUMP OUT OF A F**KING WINDOW AGAIN IF YOU DON'T SHUT UP!"

Everyone became silent because he did do that and almost broke his legs.

F:"....Well, you two could at least kiss."

D:"Yeah they are right. We all know yo- TRAY NO!" *sees Trajan opening one of the windows*

They all had to stop Trajan from jumping out of the house. When they all got him to stop, him and Kip kissed each other under the mistletoe. Trajan was a blushing mess and his friends teased him about it.

Finally it was only a few minutes before Trajan become 14, and he's feeling a bit nauseous. He almost fell to the ground but Frisk caught him.

F:"Tray!"

C:"Don't worry, it means his trait is about show any second"

So Frisk layer down Trajan on the couch. Suddenly, a white light surrounds his body. Everyone stared Trajan in anticipation.

The light disappeared, and Trajan had his eyes closed.

When he opened them, all four of his eyes glowed green.

His trait was Kindness.

Everyone cheered in celebration. Papyrus and Undyne paid Alphys 50g from each. Kip hugged him. And to his surprise, Trajan hugged back.
