- In Atop the Fourth Wall, Linkara's "Lord Vyce" story arc ended with this. Long story short, the Earth is being threatened by the feared intergalactic conqueror Lord Vyce, who claims he conquers worlds to "protect" them from being invaded by a much greater threat. Linkara and his True Companions defeat Vyce, strip him of his weapons and leave him stranded on a desolate planet. At the episode's end, we see that the evil entity Vyce spoke of is very real—and now that Vyce is out of the picture, it's free to roam in our reality. Afterward, Linkara keeps the entity's sacred tome in his possession, and he casually and routinely rattles off passages from it during his reviews. He didn't just leave our world vulnerable to attack from an Elder God—he might have unleashed it!
- Dr. Horrible's Sing-Along Blog:
- Dr. Horrible is an Ineffectual Sympathetic Villain who is unable to follow through on any of his grandiose plans for world domination and is repeatedly humiliated by his Arch-Enemy, Jerk Jock Captain Hammer. But when Hammer goes to far as to steal his would-be girlfriend, he makes it personal and gives Horrible a reason to get serious. When Hammer tries to kill Dr. Horrible with his own damaged Death Ray, it explodes, injuring the hero and revealing his True Colors as a Miles Gloriosus, and killing Penny, breaking Horrible's Morality Chain and making him a true supervillain.
- It's also shown in the prequel comics that the anti-intellectual insults Justice Joe flings at the Mad Scientist villain he's fighting are why Dr. Horrible decided to switch from admiring the heroes to becoming a villain in the first place.
- Don't Hug Me I'm Scared:
- The Red Guy:
- In the fourth video, his smacking Colin is what pisses Colin off enough to trap the puppets in a deteriorating digital world.
- It's implied in the fifth that he was calling Duck Guy and making him realize what was going on, causing Duck Guy to rebel against the the Healthy Band's lesson. Had he not tried to help his friends, Duck Guy might still be alive and Yellow Guy wouldn't be completely alone.
- And third time's the charm, come episode six; Red Guy makes two blunders. First he starts pushing random buttons in an attempt to get rid of the teachers before they can hurt Yellow Guy, but all he does is cause the system to start randomly switching out teachers, which only frightens his friend. Then when he tries unplugging the machine, it seems like he somehow reset/restarted the universe, leading to the puppets starting it all over again (maybe)... though at the very least he saved Yellow Guy.
- The Duck Guy:
- In the second video, he and Yellow Guy questioning time is what causes Tony to rot him and his friends alive.
- In the third, his swatting a butterfly leads to Yellow Guy running away and joining a cult.
- The Red Guy:
- Season 2 finale: Omega Zell tries to use a hacker-made item to quickly kill the enemys of Justice, the guild he dreams of joining. The problem is that the item works in a completely random way and all it ended up doing was erasing the avatar of Justice's top player.
- Season 5 finale: Roxana keeps Saphir from ending a major quest so the Justice guild doesn't get the honors that go with its success. The quest's purpose? Keeping the game's Big Bad who's antagonistic to all player factions from gaining more power.
- ReZonance Soundtrack Reviews: Izumi, the Non-Human Sidekick to the show's host, ReZ, has not only unintentionally made ReZ go temporarily crazy and give him Laser-Guided Amnesia due to an game she gave him, she also caused him to become trapped in his own mind just by talking to him while inside his mind.
- Channel Awesome:
- Suburban Knights: The Cloaks, the obstacles, and Jaffers are actively trying to stop the reviewers from finding the Gauntlet. Turns out they had a good reason to do so. Malachite was tracking Team 2's map, meaning that he wouldn't have found the gauntlet in the first place if the reviewers hadn't gone looking for it.
- This spills over into the following special, To Boldly Flee. If the reviewers hadn't gone looking for the gauntlet then Ma-ti would not have died, and subsequently would not have merged with the Plot Hole. In doing so, Ma-ti sets off a chain of events that leads to the deaths of The Last Angry Geek, the Emperor, Zod, Terl, and Mecha-Kara.
- In the SuperMarioLogan episode "Bowser Junior's Lottery Ticket!", Bowser Junior tries to pay five dollars to give his ticket to the Brooklyn Guy (referred to as a "stranger" here) and make him cast it, but when he and his friends come back to his house they see on TV, of all things, the Brooklyn Guy being the lottery winner and pretending he won all by himself, without any involvement from Junior and his friends. Much to Junior's annoyance and anger.Anchorwoman: Sir, how does it feel to win this much money?
Brooklyn Guy: It feels freakin' amazing! That's how it feels! Like — [chuckles] — so much money! Oh my God!
