Yeah, but the kid from South Park doesn't resemble Naruto AT ALL.
In fact, his jacket is more yellowish and his headband is a sort of lime-green.
In this case, we have a show where one blatant rip-off of Naruto has already been full-on confirmed. This chick, who fights with clay creatures that explode and even RIDES THEM, and who has a CLAY POUCH with a MOUTH for an opening...
It's more than coincidence. If it was any other show, maybe. But since we know this show DOES take a lot of shit from Naruto... For example, I just found this:
ZETSU, MEIN FUHRER?!?!?!?!?!
