GIFs of the character come after the name and the media they are from as far as ik (for the funni)

a warning that this isn't for those that are sensitive to gore.

also scrapped characters which were only suggested by @Snake_IngleBerry are at the bottom of the list.

on the far left is. . .

Tinky Winky (Slendytubbies 3 version)

my take on Tinky Winky's ST3 infected appearance is an expansion on the original face of agony with those blood curdling screams, this take on ST3 Tinky Winky still does the usual, but instead of the infection supposedly killing him, he still clings to life, his eyes have sunken in due to the Infected Custard he consumed, somehow he still can see, and if he spots you, well you know what noise he'll make.

next is Po! (also from ST3 aka Slendytubbies 3)

the Po here is from chapter 0, right as everything went horribly wrong, so she is still more Teletubby than Slendytubby, albeit traumatised that Tinky Winky has turned into the one previously mentioned.

on the middle left we have. . .

an Alternate (from the Mandela Catalogue)

unsure where they came from, but at least they as restricted to the general area of Mandela County as far as ik, Alternates pretend to be humans, and are EXTREMELY dangerous to deal with, if one hunts u down, I hope they spare u.

then there is Noob. (Roblox)

Noob isn't experienced much in anything, however he is somewhere on Roblox usually and can be very social under the right circumstances, doesn't do well when up against threats though.

then in the middle, we have. . .

Sonic.EXE (from Sonic 2011)

ya prob know him, that one demon-like sonic fan from the void with a god complex of sorts, he takes pride and pleasure in making his victims suffer which is usually Tails, Knuckles, and Eggman, specifically their classic variants, he's one of the 2010s horror characters that just stuck around in popularity terms, don't think I can do much better on how to tell ya abt this thing.

oh yeah then there's Classic Tails, he just can't catch a break, can he? (this one is a hybrid of his Sonic.EXE The Disaster (rip in rest) and the 2D remake version of him)

a genius fox that learned how to fly with a very special birth 'defect' which made him have 2 tails instead of 1, this unfortunately got him bullied but Sonic came in at the right time to help out Tails, the 2 are best friends practically and Tails has done quite a few things in the Classic era alone, however, in Sonic.EXE The Disaster, of course our beloved two-tailed friend can't have so many nice things.

in the middle right is. . .

Coolkidd (Roblox)

an alt account of 007n7, Coolkidd and his team invaded servers of popular Roblox games at the time like Work At A Pizza Place, and Natural Disaster Survival, being able to do a lot of shenanigans in the early 2010s before getting banned for exploiting and whatnot, at one point someone who knew him irl, 007e7, was open to answer stuff abt 007n7 for a bit, however left Roblox permanently on his own accord due to an incident he doesn't want to talk abt, also 007n7, Coolkidd and 007e7 got featured in a popular Roblox horror game, I'm sure u would know the one.

Bonnie the Bunny (FNAF 1 version)

the palette for Bonnie here is almost as inconsistent as the one he has in FNAF 1, despite me believing in Bonnie being blue, the FNAF lore is too much to explain here but basically there is a child's vengeful spirit inside Bonnie and I think Bonnie mistook Mike Schmitt (the guy we play as in FNAF 1) for the person who killed him due to the similar uniforms, but when he isn't scouting Freddy's at night he is a pro guitar player on stage with Freddy and Chica as far as I'm aware, Bonnie also has a lightly-coloured bunny tail and buttons in my design of him in my design, sorta merging him with his FNAF 2 appearance as a Withered and his temporary Toy replacement.

oh, then there's Hoovydundy (the antagonist of Pree Spunky's 'Hoovydundy' series)

(couldn't find one of him so here is just one of regular Heavy, srry!)

a Hoovy who got his team brutally tortured and had his whole team wiped out just as brutally taken out, he snapped under the stress and became this freak, attacking friendlies would not be advised, he is on the move in his series and if he catches someone who has hurt a friendly, he will kill them and hang up their body parts around the room he killed them as seemingly a form of decoration, as brutal as he is, it's only his retaliation from a backstory just as cruel and brutal.

then there is the far right, my 2 favs of the bunch are there.

Twisted Shelly (from Dandy's World)

The blatant ignorance of everyone around her has enraged her, and she uses her new bottom half to her advantage in terms of speed, I also feel like if she knew what most of the DW fandom is up to rn, that she would be even more enraged, a kind and pure Toon who I think got tricked by Dandy into turning into this, she accidentally was a catalyst for the whole shutdown, let's just say Dandy's ways of in his words 'upgrading' Shelly were questionable, but enough of my theory, because this part's abt her, and well, at least she sorta became what she loved. (prehistoric dinosaur-like lower half)

then last but anything but least in my book is. . .

Shelly (also from Dandy's World)

this Toon might look simple at first, but much like a lot in Dandy's World, her depth is noticeable to say the least, she's one of the least popular Main Character Toons out of them, but that doesn't stop her from having such a bubbling personality, her main interests are prehistoric stuff, but mostly Dinosaurs, she isn't a dino though contrary to popular custom designs (dino tails on Shelly (if not on the dino snore skin) just ruin the custom design for me because she's more of a 'supposed to love it and not be it' ordeal, like how I love Shelly and I'm not a Toon like she is, that kinda thing, but enough of my preferences,) her closest friends are her Toon Handler known as Shanon and Tisha, and I'd say both Tisha and Shanon are just as close to Shelly friendship wise, the latter even known to nickname Shelly 'Shells', so yeah, yall do really misunderstand a ton of things in Dandy's World, but I KNOW BETTER. (I read a LOT of the wiki lol)

P.S; I hope Shelly, Noob, Po, Bonnie and Tails are ok after this.

now for the scrapped 6, there is;

Banban, Nabnab and Jumbo Josh (Garten of Banban series)

A crazy series to say the least, that is I think less abt 'mascot horror' nowadays and is more of just 'mascot', regardless it is still mascot horror so I did try to fit it in, nonetheless Banban I think has a crazy side, Nabnab has a 'hellish' form that arachnophobes will hate and Jumbo Josh is just brute 101.

oh and then there is one of @Snake_IngleBerry 's funni characters (a cat like one with a hat)

(unfortunately no GIF for this guy, rip in rest.)

it one of of Snake's recommendations, like the 3 previously mentioned, and with how Sake introduced me to it again, I mistook the creature for Catnap from Poppy Playtime until he mentioned the thing wore a hat, from what I recall the character Snake mentioned was quite the devious but weak individual, so yeah.

speaking of Catnap. . .

Catnap and Dogday (from Poppy Playtime)

2 of their group (The Smiling Critters,) the in-game story for these 2 is kinda gruesome, Catnap is the main antagonist of Chapter 3 and Dogday got the short end of the stick, let's just say that, not to mention Dogday's body get consumed from the inside because of mini versions of The Smiling Critters group, essentially being the toys in-game just sprung to life, much like DW, lore is there but usually unnoticed, except I think Poppy Playtime is more well known (might need to double check that,) also the two if they made it in would be next to Coolkidd and Noob respectively.

rip in rest those ideas.
