HELP HELP HELP HELP HELP HELP HELP H EXPERIMENT CONCLUDED- GLaDOS --------------------------------------------------------------------------------------- That was their backstory. In the form of a log. Now, for their actual bios. Name: Orange (CoPE4171) (Core of Portal Experiment #417 #1) Gender (kind of. they were cores.): Female Personality: Hyper, optimistic, and impulsive. Abilities: Can shoot an orange portal out of her eye. Connects to Blue's. Name: Blue (CoPE4172) (Core of Portal Experiment #417 ) Gender (kind of. they were cores.): Male Personality: More serious and logical than Orange. Abilities: Can shoot a blue portal out of his eye. Connects to Orange's. Additional Backstory: They survived GLaDOS' reign of terror. Mostly because neurotoxin didn't affect them, and their feline agility and speed made dodging turrets easy. The experiment took place near the generator, so they never shut down due to loss of energy. After Chell defeated her the first time, they spent their time with botany, and had a garden of sorts. After GLaDOS awakened, and after the events of Portal 2, they met GLaDOS for the first time, who was surprised they were still active. She allowed them to roam Aperture, since they were no nuisance to her. So, there they stayed.
