(Not that anon.) SU is old. AT is ancient. Ben 10 is kind of old now and also a reboot. An example from current year might be The Last Kids on Earth. The main character is obnoxious, but he's a straight white lead. (Of course he's also a useless buffoon next to the mandatory badass action girl in the group.) I haven't watched Rise of the TMNT, but I'd say the turtles qualify as white, though of course that's another reboot of a much older franchise. Ollie's Pack qualifies, but that's not an action show. I like me some Big City Greens, but, again, not an action show, and Cricket isn't exactly a competent protagonist anyway. Sprig from Amphibia might qualify if you ignore the fact that he's, you know, a frog. Actually Glitch Techs might count depending on how you feel about Hispanics. I always thought of Marco Diaz as white.
I like Kipo. I did notice the lack of whypipo, but I never felt like the show beat me over the head with it, and I appreciated Kipo's parents being black male/Asian female instead of the same old black male/white female combo you see in every show ever.
