It takes L an entire arc to solve there myteries
It takes the scobby gang 1 episode
theres your answer
You guys are missing the point here. Scooby and the gang go up against criminal masterminds at the level of Dr. Doom and Thanos that have discovered that the key to scarring people away is to dress up like monsters. And they go up against geniuses like this on a weekly bases and solve the case within the night. Where as L only goes up against moderately intelligent criminals who haven't even figured that the best plans involve costumes that scare away people and even then it takes him entire arcs to do so. Scooby and the gang stomp.
scooby do owns allYea, and since when did the Scooby villains leave clues? scans or it didn't happen. But going by feats, the scoob team wins. They each had 2 Live-Action movies, but Scooby had 10 different series based on the scoobyverse, and a Johnny Bravo spin-off. The Scooby gang also has about 40 years experience. I don't think L is even 40, plus The SD gang are basically immortal/ eternal youth. They haven't aged at all the entire series.
