Vincent Van Ghoul

I took elements from his classic and Mystery Incorporated designs and threw in some Doctor Strange influence.

Flim-Flam

Curse of the 13th Ghost was my main influence for his outfit but unlike that movie I didn't make him suddenly older.

Marcie Fleach (Hot Dog Water)

My main influence was her outfit from Menace of the Manticore. Like Velma I gave her a Hex Girls badge.

Some extra alternate costumes. Red shirt Shaggy, Cyber Chase Scooby, Mystery Incorporated Velma and Get a Clue Shaggy.

Think my design choices were too different? Here they are in their classic outfits. And since I was making alternate outfits I also decided to go with the A Pup Named Scooby-Doo designs.

Fred

Fred's design is mostly influenced by the hoodie he wore in Scooby-Doo and the Loch Ness Monster with the bulkier proportions from his Mystery Incorporated and Be Cool Scooby-Doo designs.

Daphne

My main influence was one of her The 13 Ghosts of Scooby-Doo designs. Originally I had a darker colour for her jacket like in Curse of the 13th Ghost but realized a lighter colour looked better with the darker dress.

Velma

I made the sweater yellow as a nod to her A Pup Named Scooby-Doo design while the darker hoodie is influenced by the one image we've seen of the upcoming Velma series on HBO Max. The alien on her sweater is because of my idea of making Velma an Occult Otaku.

Scooby-Doo

Not much you can do differently about Scooby's design. I did consider giving him a darker snout like many Great Danes with brown fur have in real life but it didn't look right.
