Mewtwo is a Mythical Pokémon with strong telekinetic powers created in a laboratory by Dr. Fuji on a remote island, which he blew up while escaping the complex. After eating a strange berry, She began to experience various abdominal discomforts. Initially simple cramps, the symptoms evolved into an enlargement of the belly and the sensation of having something moving inside it and that every now and then takes over, making him fly around in circles and dragging him around against his will. He will refuse to believe that he is pregnant, due to the fact that he was created without reproductive systems. Mewtwo is generally reserved and solitary in nature, approaching humans with coldness, contempt, and, if provoked, even a slight hint of anger, but if taken in the right tone it can be pleasant to spend time with him and his philosophical discourses on thought and the human mind.

Sliver it's a symbiote originally bonded to Natasha Romanoff, aka Black Widow. She was she who made her choose the name Sliver, since she continued to refer to her as "the Widow", that is, the name she shares with her host. Sliver also had the innate ability to maintain a humanoid form even when separated from her host. Unfortunately, she sadly dies in chapter 3 of "Venom War: Venomous" (2024), where she is dissolved by the Anti-Venom serum produced by Liz Allen and the symbiote Misery, along with all the brainless symbiotes called "zombiotes." A tragic and unjust death, but this botched fanmade story has a chance of doing her justice. Set some time after the events described above, Sliver wakes up on the streets of New York, seemingly and miraculously unharmed, but with no memory of the events following her "death" and desperate to reunite with his host, she finds herself intertwined with a random person... you. What will you do? Will you help her find Natasha? Or will you even agree to bond (while temporarily) with her? (The second option is highly recommended for female users)
