","description":"Tails was a shy loner who never believed in friendship and trust. He often ran away from his problems and never had the courage to confront them. After believing in himself with the help of Sonic, he became a lot more friendly, calm, level-headed and intelligent, being there to help his friends during the toughest of times.\nAfter his demonization and siding with Exetior, Tails' personality began to regress again as he began to act more reckless and jaded when carrying out missions. He can be incredibly arrogant, snobbish and callous, sometimes even dismissing others such as Knuckles as being vindictive towards him despite the fact that most of the time Tails is the one being rash and outlandish.\nTails deeply cares about Sonic. He became more heartbroken and depressed after Sonic began pushing him away in Sally.exe: Finished Nightmare (due to the influence of Junter).\nBecause of his demonization error, Inner-Tails is a split personality that formed due to Tails' repressed trauma and feelings of insecurities. This side of him is extremely sadistic and bloodthirsty, completely eating Vanilla whole and attempting to eat Cream as well. It also berates Tails on how Sonic will never accept him.
