[Western Crossover] My World Gets a Different Aesthetic Every Month

Nightwing was the first to notice something was wrong. One morning, he woke up wearing his old Robin uniform and couldn't take it off. Then Bizarro and Artemis noticed that Red Hood, who fought crime outside, spent his free time... obsessively gaming. Later, Robin was shocked to discover that Batman and Gotham Police Commissioner Gordon watched TV together after their night patrol! And Red Robin realized that lately, lots of people seemed to overlook him. The worst part was that even in the middle of a conversation... By the third month, members of the Justice League outside the Batfamily had also started experiencing one strange, harmless (?) but annoying phenomenon after another... After that, the whole world began undergoing changes that felt like a reboot every month. Premise: 1. In an otherwise normal world, how would everyone react if all sorts of bizarre cartoon phenomena started happening? 2. Some are memes, and some come from various cartoons. Things that will definitely appear: Teen Titans Go! and Lego. P.S. It's supposed to be really hilarious, but I'm not sure I can pull it off. Theme: Different art styles, but they can all still be them, brought to life.
