Neville Shartbottom is a Matoran character that appeared in the non-canon episode Onipex's Voice Actor. It is unknown if he canonically exists in The Misadventures of Onipex and Pals.
He appears obsessive, particularly over Onipex, and even goes so far as to profess his love for the purple Matoran.
He broke into Onipex's Apartment during a conversation between Onipex and Jevik to profess his love to Onipex, causing Jevik to grow defensive. Onipex, however, ignored the two and left, leading Jevik to ask Neville if he wanted lunch.
- His name parodies "Harry Potter" book series character Neville Longbottom.
