Fact core
A loud, fact-throwing core from Portal who makes no sense and lies constantly. It’s the reason Wheatley got brainwashed into being a total idiot.
Fact core yelled 'Sharks have 5 hearts!' and then laughed like it was the funniest thing ever.
It told me 'Rabbits can count to 10!' and I had no idea what that meant.
Fact core screamed 'The Earth is flat!' just as I was trying to sleep.
