Sally Acorn

Princess Sally Acorn is the daughter of the former King Max Acorn and brother to the current king, Elias Acorn. She was sent to the sanctuary of Knothole Village by her father when the Great War was going badly for the Mobians, and lead the Knothole Freedom Fighters against Dr. Ivo Robotnik when he took over five years after the Great War's end.

Supposed "Death"
When the four-part saga "EndGame" was first written, the intent of the writers was to remove Princess Sally from the comic permanently. The idea was to kill the character with enough dignity to not drive away any of the character's fans. During a mission inside Robotroplis, Sally is slain after her rappel wire is cut, sending her falling several stories to the ground; Sonic was framed for her death.[10] The reasoning on the part of the writers was that the arrival of King Max would displace Sally's power, making her unnecessary, and that the restrictions placed on the book by SEGA made it too difficult to continue writing the character as having a relationship with Sonic. SEGA, however, had promotional plans for the character and ordered her to be revived. The character's return was written into issue #50, which interfered with scheduling and caused several pages to be cut.[11] The issue was later revised and reissued as a Sonic Super Special.
