Let's have a fun weird thread.

Go to your pokemon/reaction folder, then go to https://www.random.org/ or any random generator,
get a random number and choose that numbered image from that folder.
Pretend that you chose that image yourself and say something involving that image in someway whether it be a supplement to your post text or your post text being about it.

Try actually reply to people following these rules, wait if you need to

Roll again if you need to, like you get a weird image.

eg;
I get a picture of nidoking screaming, my post RPs as nidoking screaming about how it only wants to fuck young girls and not old hags (a joke about how it breeds)

eg2;
I get a picture of charmander dead in the water, and decide to reply to the nidoking poster.
My post is cynical in nature and talks about death in the pokemon world is still a mystery and our time is short and how it wouldn't really matter what you do in life as long as you enjoy yourself or something like that.

eg3; I get Looker flashing a badge and reply to the nidoking and charmander poster saying that they're under arrest.

I think you get the idea, just adapt to your random image.
