Media of origin:
Battle For BFB/BFDI
X Finds Out His Value
Four is an integer and the main host as well as the main antagonist of BFB, and the non-canon one-episode series, Battle for Permission to Meet 10. Four and their co-host X first appeared in the 2008 video "X Finds Out His Value". They appear to be abstract beings representing real-life numbers, letters, or algebraic variables.
To start of the list, they have been heavily flanderized for their return as the host of Battle for BFDI (possibly even worse than Gelatin). In X Finds Out His Value, Four is a kind, caring number who cares about X's feelings and the other numbers, but in Battle For BFDI, they act like a annoying, sadistic, selfish, and near-heartless jerk who likes to abuse their powers against the contestants for fun.
They are a terrible host, abusing their contestants and even their co-host X, despite showing compassion to them at times.
Their voice is very grating to listen to.
They have little to no empathy for others. They don’t care about how others feel, as they often bully their friends for no good reason such as zapped Gelatin for stabbing them by accident in BFB 3 (even though he deserved it). He even mutilated Pin in BFB 1 and said "Pretty cool, don't you think?"
They are a psychopath, as they keep killing other characters for no reason at all and are just jerkass in general.
They are also a Butt-Monkey (particularly in the later episodes), for example, the other contestants frequently treat them badly, such as yelling at them to revive the other contestants in BFB 2, and in BFB 16, the other contestants even left Four's show to go to Two's show. However, considering Four was rude and sociopathic to the other contestants, it's hard not to say Four deserved it.
They went insane in BFB 30, where they transformed into objects and let them stay in the ground forever and leave them alone.
They were at their absolute worst in BFB 16, where they refused to let the EXIT contestants out and threw a tantrum for everyone switching.
They sometimes go unpunished for their actions to the point where they're part of the Karma Houdini trope.
They can't take criticism at all; for example, when Basketball called them pudgy, they got angry, and when Balloony & Lollipop High-Five, they got angry too and demanded them to do a High-Four.
They, alongside Gelatin, take away the spotlight from the other characters.
They treat most of their contestants like trash. Notable examples include Gelatin, Donut, Basketball, Balloony, Lollipop, Blocky, Taco, Black Hole, Clock, Loser, Profily & Gaty.
He is very similar to The character Misty Mei of the Makai Tenshi Djibril series. Both charactes are Very sAditic and like to torture other for their own enjoyment.
They are at least nice to some contestants before their character development.
To be fair, BFB would not be as good as it is without them, since they are the hosts of the show and are involved in many of the episode's conflicts. Though they could've been written better in this season of the franchise.
Though they can be mean to them sometimes, they've shown they are a good friend and genuinely care about X.
Micheal Huang's voice acting for Four can be good to listen to, although that isn't saying much.
"I, AM NEXT LEVEL, MAD."
They get their comeuppance in BFB 6 as they end up getting multiplied by A Better Name Than That and Zero (Donut).
Being the mean-spirited, sociopathic, selfish, and abusive villains they are, they were supposed to be hated in these seasons as such.
They still have a nice design.
According to X, Four being a fan of BFDI explains how Four was the "biggest fan" him sitting in front of the TV watching the show, memorizing all the episodes, and telling X one day he would be famous.
After BFDIA, Four compressed all his show's recordings into one big block, thus creating the BFDI.
