You were in the city, and you see villains are trying to rule the world, it's Hydra Karen with 3 heads, that has a freeze ray and heat ray. So, the triangle shaped is Snarky Karen, the hexagon shaped is Evil Karen, the oval is shaped is Smart Karen, then you see Baldi and Null from Baldi's Basics, Mrs. Jenkins from Kingzippy, Spring Trap from FNAF, Astro Toilets from Skibidi Toilet. Like Troop Astro Toilet, Specialist Astro Toilet, Strider Astro Toilet, Impactor Astro Toilet, Interceptor Astro Toilet, Destructor Astro Toilet, Obliterator Astro Toilet, Carrier Astro Toilet, Mothership Astro Toilet, Astro Juggernaut Toilet, Overseer Astro Toilet, and Astro Duchess Toilet. She uses her normal form or her Titan form for upgrades to the Mothership Astro Toilet. And the last 2 are Neil from Raldi's Crackhouse and Sans from Undertale.

Snarky Karen: Well, well, well. What do we have here? Some human that is trying to fight alone?

Evil: Let's blast them! Say night, night!

Smart Karen: Hold it. We must get the human to meet our villains.

Baldi: Hi! I'm Baldi! I'm going to get you with my ruler and you will pay for getting my questions wrong!

Null: Aha! You idiot! Do you really thought you could actually beat this? No. Glitching Nah, you see, all of my friends are here for good. So, *Glitching quit the game! Right Glitching now!

Mrs. Jenkins: You better stay off of my lawn or I will get you with my powerful nerf gun!

Spring Trap: Hahaha! Do you really think you could stop me? I'm Spring Trap and I am holding an axe!

Astro Toilets: Skibidi, dop, dop! Dop yes, yes!

Astro Juggernaut Toilet: You... There is no escape.

Overseer Astro Toilet: This is just the beginning.

Neil: Haha, all right. I see how you wanna play this. No matter how many warnings I give you, it just seems to me that you don't wanna listen. Ahh, listen here, bud. I'll give you two options. The first? We end this right here, right now. And the second? Ah HA ha! I lied about the second option.

Sans: You gonna have a bad time.

The villains are ready to destroy you and rule the world, prepare for that. This is just going to be extremely harder!

You could also make an OC if you wanted too.
