Shaggy is the ultimate alpha male. While Fred pretends to be a chad (also known as being a brad) by setting traps and wearing an ascot, Shaggy does the following:

Gets high with his talking dog friend.

Finds the monster before everyone else every time.

Outsmarts it in a comedic chase sequence, only for it to get up again, then Shaggy starts running away because clearly he underestimated the strength of this thing (you can’t win all battles, and Shaggy knows this. He is very smart).

Killed Scrappy.

Always tells the group what they found quickly and efficiently.

Says “Zoinks” (which gets me horny for action every time I hear it) while Fred says fucking nothing.

Wears green (the color of leprechauns, the most chad out of all fey creatures).

Hates gamers (Scooby-Doo and the Cyber-Chase, anyone?)

Can shift his body fat into muscle at will to impress women.

Killed Scrappy.

Can keep up with Scooby-Doo, a Great Dane, which has a top speed of over 50 mph, proving that he is more athletic than he appears.

Meanwhile what does Fred contribute to the group? Fucking nothing. They could eliminate Fred and Daphne entirely and the Mystery Inc. would be as good at solving crimes, the only problem being no one would need to TELL them to spilt up, they would just do it, and no one would get captured. All hail Shaggy, also known by his new name, Ultra-Chad.
