One Green Lantern crossover put an unbelievable twist on the franchise's mythos. The rules of the hero's fear-powered rivals, the Sinestro Corps, got an interesting rule change thanks to a surprising duo of cartoon characters.

While the Green Lanterns are the most well-known ring bearers in the DC Universe, they aren't the only ones. The Corps is but one of seven divisions that make up the Emotional Spectrum. Like the Green Lanterns, the other factions that make up the Spectrum are powered by a light that is connected to a specific emotion. Sinestro, the fallen Green Lantern, fashioned his own Corps using the Yellow Light of Fear. Much like how the Green Lantern Corps is composed of those with the strongest wills, Sinestro chose the most terrifying beings in the galaxy for his army. It was so effective that the Sinestro Corps nearly destroyed the Green Lanterns in the Sinestro Corps War event.

Scooby-Doo and Shaggy Change the Rules for Green Lantern's Enemy

In Scooby-Doo Team-Up #6 by Sholly Fisch and Dario Brizuela, Mystery Inc. is summoned to the Hall of Justice to help the Super Friends after a collection of ghosts begins haunting their headquarters. One by one, the superheroes disappear before the ghosts are revealed to actually be the Legion of Doom in disguise. Sinestro tries to use his Power Ring to apprehend Scooby and Shaggy, but the relic instead chooses to induct the duo into the Sinestro Corps. Fred deduces that because Sinestro's ring is powered by fear, it would obviously gravitate to Shaggy and Scooby. When Sinestro asks who they could possibly instill fear in, Shaggy says that he and Scooby-Doo scare themselves all the time.

The idea of a Yellow Power Ring operating off of one's own fear might sound strange, but it actually makes sense in canon. New recruits for the Sinestro Corps are given a drained Power Ring and trapped in 'fear lodges' and forced to power their ring with their own nightmares to show they truly understand fear. This idea is reinforced when Sinestro's ring calls Shaggy and Scooby personal fear "The greatest fear of all". Not only is this humorous to think that a couple of scaredy cats could be the most powerful Yellow Lanterns, it completely turns the concept of the Sinestro Corps on its head.

Sinestro is Officially Not the Strongest Yellow Lantern

Sinestro was the one to pioneer the Yellow Light, and presumably, he knows how to wield it better than anyone else. But if the greatest fear of all belongs to the most terrified, then that means the Sinestro Corps' founding member and leader isn't the most powerful ring-slinger. Shaggy and Scooby's brief encounter with a ring proves the ones most adept at using yellow Power Rings aren't the ones who can instill fear in others, but those who feel fear down to their core. But if that's the case, then Sinestro, someone who rarely displays fear, could never be as powerful a Yellow Lantern as Shaggy or Scoob-Doo. Green Lantern's nemesis might think he understands fear, but he's got nothing on the two biggest yellowbellies in cartoon history.
