I liked the first idea, reminded me of Little shop of horrors,
Like have someone start off as it, somewhere randomly on the station, and have it so they can whisper to people.
Try to whisper to someone and it makes them an antag with an objective of feeding it meat. Start off with food from the chef, or monkeys, then eventually get a mission to feed it people. Each time it's fed it gets stronger and stronger, and the end game could be it gets strong enough that it's able to move on its own, then it become a sort of blob scenario, where it's moving around the station destroying shit and people have to stop it.
Also I liked the idea of the serial killer mode, where antags get more objectives as time goes on. Maybe just edit normal traitor mode, to where if the traitor completes their objective, they get another one after 5 minutes or so.
Also, I had an idea, what if there was a traitor mode, where everyone on the station except security are antags.
I think that would be fun.
