Infected Guardian is a white slendytubby that has white fur, pale skin, and his mouth and eyes are bleeding. He doesn't have an expression, carries around a chainsaw, and has pitch black eyes, hinting at why he can see. His main habitat is what me, Narrator, would guess to be Military Base(an outdoors area with concrete and metal buildings). He wears Dipsys old white top hat with black spots. He knows more than every slendytubby, such as how slendytubbies can't speak languages and can only make any sound with their mouth or body tissue, or the fact he knows that slendytubbies don't attack eachother on purpose. He is hostile.

Cavern Lurker is a brown furred, very tall slendytubby with the average light-tan skin, but he has glowing white eyes, one hanging out its socket, the one hanging out the socket never seems to leave the body. Cavern Lurker is also very hostile, he likes to charge into stuff using his giant flesh spike arm. He overall has a stocky, short but very muscular build. He has very incredible strength and has an outstretched jaw that ends somewhere above his chest. He hates everyone. His main habitat is well, obviously, Tubby Caverns.

Headless Brute was once Dipsy, a lime furred teletubby, but that was before he was infected. Now, with the help of Tinkys strength, he has a cut that ends at his belly, the very long cut exposing mysterious long, sharp teeth at the sides. He has no head, as Tinky simply ripped it off. Dipsy carries a chainsaw and has bloody hands. He charges into things. His main habitat is Custard Facility(a bunch of buildings with a big metal box somewhere around it having Tubby Custard(a pink, nutritious, delicious goo) that has the virus in it, being known as the Custard Supply).

Tinkerz, or Tinky, is a purple furred slendytubby who caused a massacre. He has incredible strength and bleeds some mysterious black liquid from his neck, the mysterious black liquid also going down out of his constantly open mouth. Tinker screams, making him sound like an insane woman. He is very hostile, making him Sergeant Miles least favorite slendytubby because Tinky is very hard to run from. His main habitat is Mainland(a grassland with hills and flowers, having a small dome definitely built for teletubbies and not larger stuff that has 4 beds in it).

Laa Laa is a yellow furred, tall, lanky slendytubby with elongated limbs. She is noticeably skinny and has no eyes, causing her to use hearing to hunt. She makes distorted whimpers and makes a distorted roar that sounds like a flexible thing twitching around quickly but distorted. She has a scar at the top and bottom of her eye area. She lives in the ruins of Outskirts and knows all slendytubbies don't exit the area they stay in. Laa Laa is more hostile than Newborns when it comes to hearing a noise.

Wimpers, or Po, is a slendytubby who was hung by Tinky before being reborn by the virus, just like how Tinky decapitated Dipsy when going infected. Po has red fur, has a rope around her neck, and has 4 arms sprouting out her back, all having long blades at the ends of the arms instead of hands. They help her be able to climb and stand up on them. Wimpers has red glowing eyes and is highly aggressive. She resides in the metallic maze that is actually the 'Satellite Station', where some bridges and unique rooms are.

Newborns are hundreds, if not thousands of armless, tan furred, gray skinned slendytubbies that have pitch black eyes and scream a high pitched version of Tinkerz scream. They all are aggressive and have hard craniums, being able to break through stuff using their craniums. They got the name 'Newborn' from eating newborn teletubbies. Their main habitat is Secret Lair(a bunch of brick and concrete tunnels with crates that are very dark, making Newborns have increased hearing for any very loud thuds or other sounds).

Stunners are tubbies from Tubby Military. They can stun the slendytubbies for about 5-10 seconds. They usually have dull green fur with dull green combat helmets that have visors. They are serious and will help everyone collect Tubby Custards for reasearch. They know Tubby Custards are some delicious, nutritious pink goo but resist to have any.

Survivalists are blue furred teletubbies who love being enthusiastic. They haven't been infected by the virus at all and are very scared in the situation they are in.
