2017

YouTube
In Broken Code, you can see 2017 with little colors showing. Eye, shirt, pants, shoes, etc colors are unknown for now. And we have no info on him.

In 【﻿Ｉ　ＷＯＮ＇Ｔ　ＬＥＴ　ＹＯＵ　ＧＥＴ　ＡＷＡＹ　ＷＩＴＨ　ＴＨＩＳ】, you hear 2017 say, "You're looking for him... 2017? I know him, he's me."

It is unknown if the person with a beard in the video is 2017, cause they were there the entire video, meanwhile when 232 spoke, he faded away when he was done, 2015 is unknown since it didn't show the full thing.

(UNKNOWN)

Hints
Melody said that we've seen him, and is hiding in plain sight.

Melody also said that a year could be somebody else and not a Brayden, so it most likely isn't a version of Brayden.
