Garry also counts. On a Facebook poll, he was voted the most popular villain in the comic.
There's also Coyote. When Lazerbot made a poll asking readers whether they liked Coyote, literally every vote said they liked him.
Don't forget Underbite Troll. He got popular enough to have a miniature spin off.
Fridge Horror: In Donkey Kong's first appearance in the comic, he was shown sleeping after having a threesome with Knuckles and Rogue. In his most recent appearance, he's prevented from helping the Troll Slaiyers out because Rogue gave him Gonnorhea. No points for deducing what this means for Knuckles.
It becomes Ascended Fridge Horror after the weed party: Knuckles knew he got the clap from Rouge so he invited her to the party (along with several other girls Knuckles gave the clap) to pass it onto Cheeto Man.
God-Mode Sue: The Troll King skirts dangerously close to this trope thanks to his Seven Deadly Curse Words, that would let him easily steamroll almost the entire cast if it weren't for a severe case of Genre Blindness that causes him to only use it as a last resort.
It seems to be implied that each of the words can only be used once or they lose power if overused.
Growing the Beard: At first, the comic gained attention due to how ridiculously bad it was. But as the story went on, the characters become more rounded, and Lazerbot's art improved drastically, and as a result, many people have actually become invested in the story, and have grown to like it unironically. It's difficult to pinpoint an exact moment at which people actually started caring about the story, but many will proclaim the 4th chapter, to be the point where the comic starts making big improvements, quality wise.
Memetic Mutation: Probably the reason why it has gotten so much attention on the internet is for how hilariously bad it is, and the fact that said hilarity made some memetic mutations. Many panels from the comics have been used as reaction images on imageboards and avatars on forums. We could sit and discuss them, but we'd be here forever, so for the really well-known ones...
"I'm so mad. im gonna have sex with my girl friend so I wont be so mad"
In one panel, Bugs Bunny is shown with the caption "the gay". It only took a few moments to guess how memetic the phrase eventually became.
"High shovel" has also became a popular meme.
"Sorry tails if this looks gay to the viewers."
"What? I don't have fucking ears"
"did you know that even with seatbelts people die all the time in car crashes? i thought that was interesting"
"Have you ever been bitch slapped for lack of listening? lack of doing what your told? cuz im not far from slapping you"
Nightmare Fuel: Dr. Eggman raping Amy to the point where she attempted suicide, not at all played for laughs.
Teasing Creator: Lazerbot, all the time. The most glorious example was his fake killing of Rob - what followed was a text-only panel where Lazerbot explained that basically no one is safe, fan-favorite or not.
Shocking Swerve: Quite a few plot twists come right out of nowhere, like the revelation that the guy with no ears is a Dragonborn, or Elmer Fudd being a necromancer.
So Bad, It's Good: Very much so, although the story manages to be oddly compelling and memorable in spite of the so-bad-its-good elements.
Unexpected Character: With members such as Batman, Doug Funnie, and Hello Kitty, the members of the Defenders were a surprise to everyone.
Viewer Gender Confusion: Alex the Emo Troll. Some people unknown with the comic have commented on him being a girl.
The Woobie: Tails. The title says it all, "Tails gets trolled." He also gets beaten down constantly by the trolls, gets ridiculed by them, and loses his best friend Sonic to the trolls.
Porky Pig. He's a religious fellow that got involved in a ton of bad events, eventually making him one of the Neutrals. When the Church he is a part of finds out, they see him as evil incarnate and kill his father and his mother before he has a chance to see them, and then murder his wife and child in front of him. It's no wonder that he is Driven to Suicide.
Mario and Luigi. One of the biggest moments of Mario's flashback is them meeting their parents, only to be told that they aren't loved and that their father just enjoys having unprotected sex. Luigi more so, because he was mostly dragged into doing all of this for the sake of his brother.
Amy Rose in "The Storm".
Any of the Defenders who aren't willingly working with Cheeto Man, but instead kept in line through Cheeto Man employing blackmail or I Have Your Wife. Kermit, Pac Man, Spyro, and Arthur are confirmed to be in this situation.
