Snively and Regina were having fun before you came along and a boss fight with them ensues. If you win, you proceed straight to the boss where you can see Snively and Regina Ferrum using Antoine and Rotor as sex toys while leaving Bunnie, Nicole, Tangle, Whisper, and Sally as Breeding Stock for the bugs.
He will use his weapons to whip, rape, Impregnate and dominate you. If you lose, He will bring you to a Cage in which you will have to fuck every single enemy you have faced thus far before being free and fighting Mega Man himself. A boss fight begins with Mega Man from there. With the power of the Love Emeralds, Venus brought in Mega Man and and a few other Robot Masters scattered across Mobius and made them another lewd minion of hers. By zone 6, they will reach the entrance of a BDSM club with the Bouncer being Mega Man. When they give birth, it will spawn another enemy just like with the squid back in stage 3. They will either give birth at the end of the respective zone or if they die. If the Player is raped, then they will be pregnant for the rest of the stage.
Tangle, Whisper, and the Freedom fighters were sent there to deal with the situation but never came back. Stage 6: Mewfertiti Park has been infested with Insects and Slimes who lay their eggs into people.
