No problem with Kara and the Legion, there's a lot of history there. Clark being the one who introduces them makes it more than acceptable to me.
Wasn't there a thing for a while where the animation couldn't use Zod for some reason?And they’ve never done an animated movie where he goes up against Zod, weird given how popular Zod is on the live action side.
They used Zod in Young Justice and Justice League Action, and maybe he's shown up in a couple other cartoons semi-recently so if it *was* a thing, it's not now. But I swear there was some weird contractual bullsh*t that forced the older stuff to use other characters. Like that STAS arc with the Zone prisoner who was Zod in all but name.......
