I can’t stop looking at this GIF as it gets reblogged.
Isn’t Naruto drawn by Mad House as well? That might explain the similarities from that early episode of Naruto when Sasuke’s fighting a disguised Orochimaru and The Hateocracy episode from Season 3 of the Boondocks.
Naruto was animated by Studio Pierrot. Mad House did Death Note and some other higher quality works. I guess Aaron McGruder liked this scene too and wanted it recreated.
