alright, lemme school your dumbass because obviously you’ve never watched scooby doo before
yes, he canonically has anxiety issues, but when it comes down to it, he is there for his friends no matter how scared he is. he cares very deeply for his friends and he would absolutely not hesitate to put himself in danger to keep them safe
in ‘music of the vampire’ when the vampire threatens his friends, shaggy’s first response is to grab a bunch of wooden stakes to attack the vampire with
later in this same movie when he (albeit falsely) believes he’s fallen victim to the vampire curse, he runs away and gets as far away from his friends as possible so there would be no chance of him harming them or inflicting the curse on them as well
and in ‘camp scare’ when the fish monster they’re dealing with hurts scooby, shaggy’s first response was to shatter a two-by-four across its face. watch it go down here, skip to about 1:30
during the climax of ‘legend of the phantosaur’ after struggling with his anxiety for the whole movie, shaggy overcomes it for the sake of saving the lives of his friends and the villains who put them in danger in the first place
in ‘ghoul school’, without any help from fred, daphne, or velma, shaggy saves the lives of several monster kids, and in ‘reluctant werewolf’ when he’s cursed to become a werewolf, he wins back his humanity in just under two days, again without help from fred, daphne, or velma
hell, the whole plot of ‘goblin king’ was about shaggy and scooby travelling into the realm of monsters, the very things he’s afraid of mos, so he can save his friends from being turned into monsters themselves. and he does save them
and those are just the examples i could think of off the top of my head!
shaggy is as essential to the gang as everyone else is. he’s the one who repeatedly throws himself headfirst into the path of the monster of the week to lead it into fred’s traps, despite his anxiety issues, because he’s the only one fast enough not to get caught. fun fact! he’s won multiple awards in high school for gymnastics and athletics. he isn’t just all about fear and food. he’s a friendly, caring person who would do anything for his friends, and on top of all this?
he’s only seventeen. of course he’s scared, he’s just a kid.
tl;dr, shaggy rogers is more than his anxiety
