I got some headcannons for em as well! To start us off I'll give you a few general ones before going into the characters.

All of the stickmen are biologically gender neutral, there is literally nothing in their pants-

So when they found out about the different genders they were like, huh? Neat and after some self discovery they assigned genders to themselves.

They all have anger issues. This is practically cannon at this point tbh-

The sticks can only eat and drink whilst connected to a game that allows them to do so.

The Second comings group are all in one big relationship, they are not afraid to shower each other in affection when the time calls for it.

Blue made his friends friendship bracelets and they all refuse to take them off.

All of the sticks are mute...but can somehow talk to each other telepathically...Alan does not share this trait obviously.

The Second comming

They/Them ( they weren't really that bothered about the whole gender thing)

They are the mom friend of their group, constantly trying to keep their friends out of harms way.

A natural leader, if they or their friends do find trouble they are almost always the one who steps up to get them out of it.

After their first experience with Alan they were nervous and over protective of their new friends...but after the PvP incident they calmed down a bit.

They don't really trust Alan all that much. But since its his computer they've come to terms with the fact that they don't have a choice but to get along with him.

Green

She/They

She is incredibly creative, but it's an organised kind of creative-

She has OCD

She is a bit of a showoff

She mostly creates to ether impress her friends, or make their lives easier.

She is the most emotionally sensitive of the group...but also a bit pushy in how she handles said emotions.

The constant smothering from TSC was coming from somewhere...and Green felt she was the only one who noticed-

That was until she saw Red and Blue trying to talk things out with TSC, she joined the conversation. It ended in a yelling match between the four sticks and a split in the group.

Yellow was completely unaware of this since she was preoccupied with her experiments.

The PVP fight happened because of the tensions that arose because of this.

After the fight TSC and Green talked it out. They share a closer bond with each other because of this.

Yellow (there was no yellow in the colour options-)

She/They (she took the longest to figure herself out...since she wanted to get all her facts straight first)

The smartest (mathematically) of the group.

Likes being in control at all times, if there is any chaos she will freak out.

Relies on Red to bring her back down to earth when she gets in a tizzy.

Very confident in her ability but doesn't take losses well.

During the PvP incident she understood where TSC was coming from...the others should've just minded their own business.

However afterwards she wasn't so sure. Especially after the talk she and Red had.

She is doesn't really understand emotions. Coding and engendering is more understandable to her.

She is autistic-

Blue

He/They

He is smarter than he let's on.

Incredibly experimental, not afraid to jump in head first with a new idea.

He is incredibly positive. Always there to be the ray of sunshine in a rainy day.

He is the chemist of the group.

The certified baby of the group...everyone seems to underestimate him because of his "childish" outlook on life.

Red

They/them (couldn't decide, so they just stuck with their previous pronouns)

They are very open to the idea of forgiveness. Following this he is the only one who has fully forgiven Alan for what he did to them.

Animals are just as much their friends as the other sticks are.

They are not afraid of showing emotion.

Intense PTSD from the herobrine incident. They are terrified of losing control and hurting their friends again.

Purple

She/Her (the only stick that actually in inforces her preferred pronouns)

Needs others opinions to determine her own worth.

Thinks big acts of courage will get her friends.

She has major trust issues, outsiders are not welcome.
