Otto (Archie)

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.

Past
Otto was born into the family which has protected one of Spagonia's Gaia Keys in secret, a duty which he eventually assumed. Becoming the dorm master at Spagonia University, Otto eventually came to be friends with Professor Dillon Pickle, though he 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 and Rotor 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, although Otto was calmed down by Rotor so he could tell who had the other Gaia Key.

Trivia

 * Otto originates from the game Sonic Unleashed, where he is a native of Spagonia.
