I hear that’s because 4Kids had less input in it, and Peter Laird & Mirage had more say-so over the 2003-2008 TMNT show.
4Kids did manage to ban an entire episode “Insane in the Membrane.” (For being too gruesome & creepy.) Banning the episode in America, even left a small gap in the continuity with Baxter Stockman.
Still, surprisingly they didn’t censor Leonardo
decapitating the Shredder (though his helmet helped obscure any gory details) like in the original comic canon.
Granted… Unlike the comic,
he survives, due to not quite being “human.“
