Pedia is a Wizard and partner of Zack Temple in MegaMan Star Force 3. Pedia's appearance is that of a dictionary with glasses and is able to access the Internet in a nanosecond. Pedia's role is nothing more than an "Info. Wizard", and assists Zack and the others by providing them with the information they need.
Pedia and Zack's names are a pun on "Zackpedia", the name of Zacks own website which he gets his information from.
