Otto is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is a human resident of Spagonia, the landlord of the student apartment building at Spagonia University and an old friend of Professor Dillon Pickle. In addition, he is a Guardian of the Gaia Keys, which are essential to access the Gaia Temple.
Otto was born into the family which has protected one of Spagonia's Gaia Keys in secret for generations, a duty which he eventually assumed. Becoming the dorm master at Spagonia University, Otto would become friends with Professor Dillon Pickle. Despite their friendship, however, Otto never revealed his duty to Pickle, even after Pickle began researching the Gaia Manuscripts.
The Shattered World Crisis
During the Shattered World Crisis, Otto gave his Gaia Key to Sally Acorn and Rotor the Walrus of the New Freedom Fighters so they could restore the planet. Otto then had an argument with Pickle, who felt he had kept him in the dark on his studies. Rotor ended the argument by raising his voice, making both men realise how foolish they were being. Otto then offered Pickle to talk about his family history over cucumber sandwiches, before telling the Freedom Fighters who had the other Gaia Key.
