I guess Seitz's more "goofy" inflections would work for Gumshoe a bit more than Willingham's. actually. But still I just hear Scott McNeil's voice coming out of him as well.
I used to watch it as a kid, but I honestly forgot how certain characters sounded, particularly considering how there are different runs that take place in different continuities.
Can you do "Miraculous: Tales of Ladybug and Cat Noir" & "Tai Chi Chasers" Japanese Dream Casts because both shows was not released in Japan despite Toei Animation was involved in both shows?
