ENTRY 8 Paper: The Near-Perfect Entry in the H series of experiments, he was a substitute from trying to recreate the success of ENTRY 7 after their disappearance, but something went terribly wrong in creating him. Causing him to become too powerful to control, and eventually released into the world outside the lab. ENTRY 1 PLUSHIE: the first entry, they were rejected from looking too "uncanny" because of this they went into hiding and began to create miniature plush versions of himself to keep him company until Henrico found him. ENTRY 2 TECHNOLOGICAL: this entry was rejected for disobeying protocol regularly, he eventually ran into the dark forest and made himself one with nature, now he is more of a gentle giant but still has a wraith filled rage within him. ENTRY 3 PUTTY: "Oh.. WeIgHt... Is tHeIr SuPpOsEd 2 B a BiO hEaR, sOrRy I eAtEd It AlL." - Hatpy ENTRY 4 MEDICAL: Rejected for his greed to take control of the entire facility and was quickly foiled, he still remains in the abandoned lab to this day, thinking he has won control over it. ENTRY 5 & 6 MENTALITY: these two constantly argue, and have an extreme obsession over obtaining a soul due to them thinking it'll give them the power to separate, due to being trapped in one body. ENTRY 7: The Perfect entry, due to the same problem as ENTRY 8, ENTRY 7 quickly adapted and became stronger and superior for the scientists to handle, eventually releasing all of the other entries and ascending beyond the mortal plane, ENTRY 7 now sees everyone as pawns in his little game..
