I can see Adult Swim quietly eclipsing anything Toonami that's out of the block's timeslot. Even Pre-Flight has Jason or Gill wear a Rick and Morty T-shirt every week despite the show having nothing to do with it. Maybe I'm just worrying.
Toonami kind of dug their own grave when they became more successful. Because they're bigger and have a bigger rep, it means they now need to compete with the other big players. The problem is that those other players beat them 100% of the time.
