I think this talk of invasion is silly, as though these aren't ideas voted on by his supporters. If they're what the people want (the people actually giving him money aka not us), we don't really get to complain about it.
Far as I know there is no rule determining what can or cannot fly with his characters, the MW cast being the exclusion for now. If Jack wanted all his OC's being untouchable unless by him, he'd say so.
If you don't want to see content of a milf doing something other than their son, fine. Just don't watch it. But don't be a lame ass and be like the character is ruined for you and you're gonna delete the previous animations they starred in, that's just weak. They're fictional characters, stop overreacting like those geniuses that flip out over Disney character casting.
All that aside now, looking forward to Anne's. Folks seem hungry for horse content around this time, since Catwoman's was also around this month last year heh. Must be a thing of the season
