Springtrap is known to be as an old Spring Bonnie spring lock suit that was rotten for 30 years until he ended up in Fazbear's Fright. He is known as William Afton as a corpse inside of the suit. He should sound like William Afton, as he is inside of a suit. Springtrap has a British accent, as he should sound evil. His tone should sound remorse, as he should look for redemption. Like he would sound like in Five Nights at Freddy's AR: Special Delivery. Try to make him sound relevant to what he sounded like in that game. Although he has the same voice as Scraptrap, he should sound a bit more menacing than him.
