Pterano has become extremely popular among fans, featuring prominently in fanworks and cited by many fans as their favourite character outside of the five main characters, or their favorite new character. Many fans claim that his voice-actor is what makes him such an appealing character, being one of the few new characters to be voiced by an actor other than a voice-actor. His voice-acting has even been compared to that of Tim Curry, due to their similar overacting and English accents.
