Shaggy is the most powerful character in any cartoon lore. Here’s why Shaggy is the most powerful than all of them. Have you ever noticed just how much food he constantly eats, while never getting fat? That’s because he’s actually spending all those calories. His body is extremely powerful and that’s why he needs all those calories to sustain himself.
But why is he so afraid all the time? That’s because fear is a weakness that the CIA scientists, who created him, gave him when they realized he was too powerful. The same applies for Scooby-Doo, which is why he eats as much as him and can talk. Shaggy was meant to be a secret weapon for the US military, but the project dropped when they realized Shaggy and Scooby couldn’t be controlled, which is why they gave them the weakness. However, Shaggy and Scooby escaped before the serum they gave took effect and wiped their memory. Shaggy was then adopted by Samuel and Wendy Rodgers, and they never told anyone.
Fred knows about this and that’s why he never feels bad about splitting up the group and using Shaggy and Scooby as bait. He knows monsters are going to be drawn to Shaggy and Scooby because of how easily scared they are, but he also knows they aren’t in danger because they are invincible. Even if he doesn’t know it, I’m guessing Skip jones must’ve worked for the CIA in the past.
