From the moment Silly PEs were implemented, you knew this guy was gonna be here. Let's just get this over with.
What’s the work?
Scooby-Doo (2002) is a live action film made by Raja Gosnell. Here, the Mystery Gang got invites to Spooky Island, where they have to stop Emile Mondavarious and his army of demons from taking over the world, but it's turns out that the true mastermind was a surprise nemesis, an old comrade (not)...
Who Is He? What Has He Done?
And that was the nephew of Scooby-Doo himself, Scrappy-Doo. Wanting revenge on the gang for abandoning him years ago, he uses the Daemon Ritus to absorb all souls in his quest for world hegemony. He begins by trapping the real Emile Mondavarious and making a robotic replica of him to impersonate him as a tyrannical mastermind.
After building his army, he realized that his monsters die when exposed to sunlight, so he had them possessed humans to become immune while Scrappy and his two henchmen, the insane N' Goo Tuana and masked wrestler Zarkos, stole their souls to absorb them. He now needs a pure soul in order to complete his transformation, so he kidnaps his uncle and manipulated him into thinking that Shaggy was not his friend, sacrificing him and attempting to absorb his soul in order to become unstoppable, but he was rescued by the rest of the gang. Scrappy then absorbs the Daemon Ritus with the other souls to become Scrappy-Rex, but the Mystery Gang to outsmart him by releasing and returning the people's protoplasm to their bodies and Shaggy uses the claw to pull the Daemon Ritus out of his chest, returning him to his normal form. He and his henchman are then arrested.
Migrating Factors?
He does a slightly understandable motive for being evil, being wrongfully abandoned by the Mystery Gang at the desert with only his suitcase with little to no means of survival. However, this has nothing to do with his plan to conquer the world nor absorbing the souls of people who had nothing to with his grudge against the gang, making his excuse very invalid at best. Not to mention, the whole reason he was thrown out in the first place was because he was being an insufferable jerk, arrogantly boasting about he'll fight ghosts with "puppy power", trying to take Fred's position as the gang's leader, saying he "did not have the scrote for this job", and peeing on Daphne and lying that it was an accident, making his motive all the more petty.
Other than that, it's safe to say he was none.
Heinous Standards?
He passes. His process of absorbing souls are very painful, as he uses the Daemon Ritus to remove the ectoplasms from their bodies and traps them in a cauldron where they cannot escape from, putting them in FWTDs, being fully aware of this. He may have more resources than the Evil Masked Figure but he uses them to their fullest to painfully absorbing souls and using their bodies as vessels for his demon army to take over the world.
Is He Silly?
Just like the good old Scrappy...
Oh, hell yeah. his entire character is just a parody of his original incarnation that was made to poke fun at how hated the original character was. Not to mention his backstory is played as as a joke than a tragedy, him growing a gut during his transformers Scooby telling his nephew to sit down and pokes him in his nose, Shaggy taunting that he's a bad dog, and his defeat where he's taken away in a dog cage and nearly curses out the gang by saying "And I would have gotten away with it, too! If not for you meddling sons of...". There's also this little homage to the original Scrappy-Doo right here.
Despite all of this, his crimes of absorbing souls are taken seriously in-universe, with Scooby being on the verge the gang doing everything they can to free the souls he captured to put a stop his plans of world conquest.
Final Verdict
A firm Yes.
