Shaggy Rogers - Shaggy Wick

Came up with plot idea…

The gang disbands due to one of them dying (haven't decided who though). Shaggy, riddled with guilt, becomes a drifter and occasionally helping people out along his way but gets a bad rap with the cops for his more brutal methods (He became more hardened after the incident). Scooby tries to be the voice of reason but its no use, Shaggy is in a rage against all those people trying to do land schemes and suckering people out of inheritance.

It ends with Shaggy having to make a moral choice, to rise above his rage… once he does it is revealed that Scooby was just a hallucination brought on by his PTSD of what happened, but now he can finally move forward.

"Raggy… What did rou do?"

"Like, Scoob, the world isn't the same as it was. The gang… They're gone now, man."
