King Frederick Acorn is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He was a Mobian squirrel-chipmunk, the King of the Kingdom of Acorn during the Golden Age and the father of Maximillian Acorn. He was known for being extremely open and welcoming in his reign, earning him the moniker King Frederick the Gracious.
Like the former monarchs before him, Frederick immersed himself in the Source of All before becoming ruler. His son Maximillian was only a young boy when Frederick granted the wizard Ixis Naugus the title of Royal Wizard. This act was part of Frederick's efforts of opening the kingdom both to its neighbors and to incoming individuals like Naugus, the first real efforts to be made in generations.
Taking in Nate Morgan
After the Overlander scientist Nate Morgan arrived on the edges of the Kingdom of Acorn, expecting to die either from the strain of his travels or by the hands of the Mobians, he ran into Frederick, who took pity on him despite the fears of his royal guard. Invited to stay at Castle Acorn, Nate and Frederick became close personal friends and Nate became the adopted uncle of Frederick's son Maximillian.
Passing on the leadership and death
When Maximillian became ten, Frederick revealed the mysterious Source of All to him, and Max soon bonded with the Source as per royal tradition. The Crown and Sword of Acorns were forged from the Source material that had covered his body. Because of their bonding with the Source of All, the Acorns were granted guidance from the Source. The Source guided Frederick to select the young Alicia to act as Max's future wife. At age eleven, Max and Alicia were betrothed, and upon their eighteen commemoration, the two formally married. As Frederick aged and Max became old enough, he assumed the mantle as king, with Nate Morgan present at the ceremony. Frederick passed away some time afterwards.
