Shaggy

Entrance
The Mystery Machine drives out onto the battlefield, and Shaggy hops out of it.

Neutral B: Scooby-Doo, Where Are You?
Shaggy cries "Scooby-Doo, where are you?!", which puts his loyal Great Dane at his side. Scooby follows his master around the battlefield, acting like support for Shaggy. He can run towards nearby opponents, but he is affected by traps and items set up in his path. After 11 seconds or after he is KO'ed, Scooby will disappear and Shaggy will have to wait four seconds to call him back out. If you press A, Shaggy will throw a Scooby Snack forwards, causing Scooby to run to the spot where the treat landed and eat it.

Side B: A Frozen Fright
Shaggy throws a sheriff's star forwards, which causes the opponent to get stuck in some ice for two seconds, temporarily limiting their movement. Holding the attack will increase the star's distance, allowing for better accuracy. If the star does not reach the opponent, it acts like a trap, staying in position for five seconds, and freezing the opponent once they land on the star.

Up B: Swoocin' Right In
First a barrier appears next to Shaggy, allowing him to go right through it and gain a horizontal recovery.

Down B: Super Shaggy Sandwich
Shaggy takes out one of his famous Super Shaggy Sandwiches, then has two options regarding what to do with it: 1. Eat it, which restores a small portion of his health. 2. Throw it at an opponent which can restore their health, but also make their attack and moving speed slower than usual. To prevent spamming, Shaggy has to wait four seconds after he eats a sandwich or three seconds after handing one to an opponent to take out another sandwich.

Final Smash: A Coward's Instinct
Shaggy starts to run and is chased by one of four monsters:

The Black Knight chases Shaggy slowly but can deliver powerful blows to those in the way.

Captain Cutler floats while chasing Shaggy, being faster, and often having the ability to swim in the air.

The Ghost Clown hypnotizes opponents in his way, reversing their controls for five seconds.

The Caveman uses his club to bonk opponents in his way. However, he is the slowest of the bunch, meaning that he is easy to avoid.

One of these monsters chases Shaggy for twelve seconds. After that, the monster disappears and everything returns to normal.
