The city is quiet as the last black Van drives out of the city, and Leviathan X is ready to be pumped through several of the city's apartment blocks. Over night woman through out the city will grow into Titans, some only a few feet taller and maybe some will tower over the whole city like goddess's, some will be muscular others gigantic mountains of curves and lust. Men are not affected and must survive, while woman must be lucky enough to avoid the gas entirely or become gigantic themselves. Which one are you? A woman who must avoid infection? or a man who must escape the city before it's apocalypse at the hands of unwilling giantess's.

Update - 12:01PM - 18/07/2026: Moved Growth Mechanics into Lorebook to help improve roleplay and limit permanent token count.

Update - 5:31AM - 16/07/2026: Added a new opener. (It's a reference to my first growth bot.)

Openers:

• Walking home late.

• Chilling out at home with your Roommate.

• Enjoying the house party with your nerdy friend.

• Create your own scenario.
  
  
  
  Things to note:

• This bot was a suggestion to make a bot based on the works of O-The-Leviathan-O and their CHAOS series of animated videos about woman being infected with a Leviathan serum that transforms them into various sized and muscled titans unwillingly.

• This bot is a scenario and has no characters made for it, there for you must either let the LLM Narrate NPC's or describe them your self. It is an RPG so make sure you write more than a couple of lines each response, I recommend at least 2 paragraphs to get the best results.

• All growth in this bot are in the form of growth spurts and are completely random per individual NPC, and your persona if you are roleplaying a woman. This means it could be anything from short small bursts of a few feet spaced out of each minute, several large growth spurts one after the other, or a single or a couple of small spurts before several giant growth spurts in succession that only happen a few minutes after the first smaller ones.

• The Maximum Size that an individual woman grows is also random, Some end up only a few feet taller while others could out grow the whole city and crush it underfoot.

• The body type gained from growth is, you guessed it, also random. there are two out comes, the first is a more voluptuous body with hyper exaggerated curves, and the second is inhuman amounts of muscle mass that would make even the hulk blush.

• The whole City is inflicted, it may be a good idea to escape before you get trampled... unless you're into that ;)

Creators Notes:
Hello! Sorry about the late post, I got scammed earlier this week so I've been busy with cancelling credit cards and changing drivers licence numbers for the last few days, The lesson is not to trust your friend sending you a Mr. beast promotion, even if it is something they might do, their account may have just have been hacked and sent the same message to everybody on their message list... As someone who has a background in IT I should have known better, but apparently I'm an idiot. Anyway, This was a suggestion from my suggestions bot, I have I think one or two more there to check out and make bots of, Honestly it's less of a suggestions bot and more like a requests bot at this point because I keep doing all of them. I'm not sure I will have time this week due to the scammer thing but I will do my best. Well thats about it, like mentioned in the things to note section above the bot is based off of the Chaos series made by O-The-Leviathan-O on Deviant art. They've been around awhile and do some really good FMG/GTS stuff, and they have a few Giant Werewolf videos too, keep in mind the quality is to be desired, maybe they are just comfortable with the program they use or it could be their art style I don't know, point is don't let the animation quality throw you off, its good stuff. With all that out the way I will see you in the comments, if you have issues leave them there, leave suggestions/requests on my suggestions bot and I will see you in the next bot while I go play the "Giantess - Size Matters NG" Mod on Skyrim and dealing with the bank. See ya =)
