well, for most of the personalities came from another chart off tumblr, but that one had only done 12 personalities and not all 16. but after looking over the personalities already given they made sense. you have your characters like t bonnie and freddy who you would expect to be extroverted, and then the ones like springtrap and golden freddy who you'd feel would be more kept to themselves. then you have the characters like toy chica and mike who if you look at rebornica's (don't know if you've heard of him/her) comics are always portrayed as judgmental. the 5 characters i had to do myself were mike, phone guy, purple guy, springtrap and phantom balloon boy. there were 2 introverted and 3 extroverted personalities left, so i gave the 2 introverted to springtrap and phone guy. springtrap because he is the only animatronic and always being surrounded by quiet would make him, as you would think, socially awkward, and phone guy because even though he is your guide to success, his never-ending stammering during the phone calls does show you that there is something hard about leaving the messages that is hard for him. as for mike, purple and phantom bb, they got the extroverts. mike because he is always represented in fan art as loud and outgoing, not always with the friendly words, however. purple because of just the general role he plays and what he's known for (cough)... and as for phantom bb, i suppose you could label any phantom as an extrovert because of how loud and careless of your business they are, but i chose BB because he was the first phantom anyone knew about. and believe me i didn't want to choose a phantom, it just seemed to me that the other characters (shadow bonnie, shadow freddy, balloon girl, etc...) were all portrayed as just too quiet for an extroverted personality. anyway that was maybe too long of an explanation, but at least you know. thanks for being interested, and you stay awesome as well
