Secret Mountain Fort Awesome characters

Main

Festro

Festro is one of the five main protagonists of one of Peter Browngardt's Animated television series, Secret Mountain Fort Awesome on Cartoon Network.

Festro is purple with green eyes, two large tusks, and 2 smaller fangs in between. He is quite muscular and only wears a pair of briefs and a pair of brocro sneakers. He has black hair(spikes) and a bald spot at the top. Festro also has purple knuckles on his fingers.

Festro is brash, crude, selfish, and inconsiderate. He has the personality of your typical college frat boy, as all he wants to do is slack off and party, and loves to punch himself in the face. He rarely takes responsibility for any of his actions and is usually taking advantage of his friends.

Despite his disgusting behavior, Festro has moments where he owns up to his mistakes. He also has moments where he will do anything to defend his friends.

Fart

The Fart is one of the five main protagonists of Secret Mountain Fort Awesome.

The Fart is a guy who is made out of butts. He has a big butt on his head that moves when he talks, and two blue eyes with eyelashes. He has a butt on his face that serves as his abs and he has three little butts on his chest that serve as the rest of his abs. He has butt cracks on his arms and legs, and butts replacing his hands and feet. He wears a green belt with a golden heart-shaped buckle on it. Ironically, the only place where he doesn't have a butt is on his rear end.

The Fart is the most sensitive and caring out of all the Disgustoids. His tastes and actions are more refined as he tries to make more of an effort to understand the humans and abide by their culture in hopes of abolishing their hatred for disgustoids. He is also the most logical out of all of them, preferring to think things through before just jumping into them.

His abilities are to harden his body as a rock, change his belt into men's brief underwear, super strength, shapeshifting, stronger abs, increase in size, geokinesis, etc.

Gweelok

Gweelok is one of the five main protagonists of Secret Mountain Fort Awesome. He is the third main character of the show. he is a very intelligent technical nerd who is a walking ball of mucus. He is voiced by Paul Rugg.

Gweelok is a slimy green ball of mucus with a bunch of shiny red pimples and little black hairs. Gweelok also has big black with white pupils,s quinted eyes with big long black thick hairy eyebrows and pink lips with yellow crooked buck teeth. Gweelok has human-like arms with black hair and sharp claws with three fingers. He has two gray metal gadget bracelets on both arms, and is shown without legs, except for in three episodes. He is the smartest person in the group.

However, despite his intelligence, he can also be stubborn and anti-social among others. He sometimes manages to take care of things himself and keeps a tight lid on his emotions. Gweelok also has an ease to lose his temper. As shown in Gweelok Cracks, he becomes red whenever jealous or aggressive, making him quite scary to be around. His social skills are developing quite slowly, and he is able to get around with the bros just fine.

Slog

Slog is one of the five main protagonists of Secret Mountain Fort Awesome. Slog is a short disgustoid with black fur covering his body and face. He has a large nose with peach colored flesh. He also has sharp teeth and eyes that are large with two red rings inside of it. He usually wears a stained orange shirt with no pants or shoes and has long yellow nails. He is voiced by Steve Little.

Slog is not well educated, making him more vulnerable to the other disgustoids manipulating or taking advantage of him. He's usually quick to follow along with whatever Festro tells him to do, though he sometimes questions the morality of the actions (IE in The Bet) and even tries to encourage Festro to do the right thing (IE in Secret Mountain Fart Awesome) even if that encouragement falls on deaf ears. He takes pride in being completely filthy and not taking a bath.

Despite not being the brightest bulb in the box, he has his moments where he is just as smart as everyone else in Secret Mountain Fort Awesome . A good example of this would be in Festro Gets Glasses where Slog insisted the correct answer to a "3 + 3 =" math problem was "6" to Festro, despite Festro not listening to him or the others. Another example of this would be in Funstro where Slog decides to take charge and develop a plan to get the old Festro back from his sadistic counterpart Funstro.

Slog also has a lot more compassion than the rest of his fellow disgustoids. This can be shown in Gweelok Cracks. All the other disgustoids are wondering about broad topics or selfish needs, but Slog was concerned about Dingle being turned into a basketball. This can also be seen in The Broken Chair. While running around on fire, he stops mid scream to come up to the screen and warn children that he is a cartoon and fire doesn't actually hurt him, but the kids who are viewing the show are real and shouldn't ever play with fire. This also shows Slog constantly breaks the 4th wall. Another example of Slog breaking the 4th wall would be in Labyrinth when he acknowledges the fact that if Gweelok doesn't complete the maze in 10 minutes, him and the others will be stuck with the Troll King forever with commercials.

Dingle

Dingle is one of the five main protagonists of Secret Mountain Fort Awesome.

Dingle is a small blue disgustoid that is similar in appearance to Gollum from Lord of the Rings. His back is hunched over with long arms and bend hind legs, his teeth are sharp, he has a rather robust chest, big round eyes, and scraggly straight black hair with a bald spot at the top.

Dingles personality is usually quite calm despite his voice sounding a bit crazed. Like Fart, he can serve as a voice of reason sometimes amongst the other disgustoids. It is also shown that Dingle is more intelligent than he gets credit for. An example of this would be in President the Fart where he gives a well thought out presidential speech that brought the rest of the bros to tears. Another example of this would be in The Broken Chair when Dingle explained to Festro what he had been doing all day, and it included activities such as inventing several things, winning a Nobel peace prize, and horseback riding competitions.

However, there is another side to Dingle's personality that can be mischievous and a bit sadistic. An example of this would be in The 6th Disgustoid when Dingle suggests that they should make fake money to solve their debt issues with the land lord. Another example of this would be in Funstro when Dingle suggests something in his usual gibberish voice and Gweelok comments on how illegal the plan he's suggesting sounds.

Uncle Grandpa characters

Uncle Grandpa

• Uncle Larry Jeff "Bobo" Grandpa, Jr. (voiced by Peter Browngardt, Pendleton Ward in "For Pete! Love, Pen") is a magical shapeshifting humanoid who is the uncle-grandpa of everyone in the world with a large, rectangular head, a brown horseshoe moustache, a pink nose, a propeller hat that talks and an outfit consisting of a white T-shirt, lederhosen with rainbow suspenders, knee high tube socks, and black slippers. His outward appearance is depicted as rather clownish and unsophisticated, but he is well-meaning, fun-loving, supportive, and surprisingly competent when need be. His catchphrase is "Good morning!"

Mr. Gus

• Little Michael Marshal "Breakfast-Mysterious Gus" Gusford, currently better known as just Mr. Gus (voiced by Kevin Michael Richardson) is usually the voice of reason. He is a large, serious, yet somewhat grouchy green dinosaur (Reptoid) who was Uncle Grandpa's rival in "Leg Wrestler", but eventually became his friend and bodyguard. He is unfazed by most of Uncle Grandpa's eccentricities and seems to have an even temper despite his roommates, but often loses his temper, especially where Pizza Steve's antics are concerned. He's older, and more mature than Uncle Grandpa. One of Mr. Gus' favorite parts of the day is 9:00 PM, which is his designated bathroom time, and during that period he likes to take a bubble bath and read for an hour. His catchphrase is "You're just sayin' that to get under my skin."

Pizza Steve

• Little Nacho Pizza Dough James Walter Stevens "Steve" Cheese (voiced by Adam DeVine, Pendleton Ward in 'For Pete!

The rainbow trail is also expelled from Tiger's rear end when she passes gas. Her personality is a cross between that of a stereotypical teenage girl, a house cat, and a real-life tiger.

Beary has a positive outlook on life while Hot Dog Person is more gloomy. Each of their segments consist of the two of them trying something different for the first time (taking a bath, getting a haircut, etc.). Beary is always excited to try whatever they're doing, while Hot Dog Person is more reluctant as it seems every time he tries something new, something bad happens to him. Beary's excitement also leads to him being self-centered, as he is so wrapped up in his own emotions that he pays no attention to Hot Dog Person's plight.
