Bernadette Hedgehog

Bernadette Hedgehog (aka "Bernie" for short) is the mother of Sonic the Hedgehog and the wife of Jules Hedgehog. Bernie was one of the students of Nate Morgan along with Sir Charles Hedgehog and future husband Jules (with whom she debated with and won all the time). Both Bernie and Jules were agents of King Acorn's special forces during the Great War. Following the takeover of Dr. Ivo Robotnik, Bernadette was subsequently roboticized and became a mindless servant of the world despot. Years later when her free will was restored, Bernie became the mother that Sonic lacked for the majority of his life.

Early Life
Prior to the outbreak of the Great War, Bernie was a student of Nate Morgan. She would often debate with Jules in class discussions, resulting in Jules having a crush on her.

Veteran of the Great War
During the Great War, Bernadette became a soldier in the Acorn Kingdom Army. When Mobotropolis fell under mortar fire from the Overlander forces, Bernie and Cocoa led the Mobians into the secret underground shelters, using their superior eyesight to guide them through the catacombes. Eventually, the two females found themselves coming up behind enemy lines. Due to this discovery, the Mobians were able to suprise the Overlanders and attack, forcing them to withdraw.

Some time after this mission, Bernadette fell in love with Jules and the two got married. Later, during a secret mission to locate and rescue the famous Mobian historian Kirby, Jules was fatally wounded by an Overlander troop. While Charles tended to Jules' wound, Bernadette attacked and badly injured the Overlander who shot her husband. Though Jules' wounds were fatal, hope remained in the untested process of Charles' Roboticizer. Unbeknownst to the both of them, Warlord Julian tampered with the machine so that whoever was roboticized lost their free will. After Charles left in disgrace, Bernie was all alone to take care of her newborn son while Jules remained idle in her home.

Life as a Robian
When Bernie discovered that Julian was using Jules for labwork, she confronted him. However, Julian simply used his control over Jules to capture and throw Bernie into the roboticizer. Soon she too was roboticized and was robbed of her free will. When Charles came looking for her, Julian lied and said that Bernie was fooling around with the roboticizer and ended up her current state, adding on to Charles' grief.

Following Julian's (now renamed Dr. Ivo Robotnik) takeover, Bernadette worked as one of the many Robians in Robotropolis. Charles kept her and Jules' existence unknown to Sonic until after Robotnik's death, as he realized Robotnik would have used them to make Sonic's emotions consume his judgement and likely result in his capture. When Robotropolis was retaken, Sonic was reunited with his roboticized mother and father, though was unable to accept they were actually his parents due to Charles having lied to him for so long.

Sonic later presented his parents with wedding bands made of Power Rings, which prevented Bernie and her husband from loosing their free will upon the arrival of Dr. Eggman to Mobius Prime. Following the second loss of Mobotropolis, Bernie and Jules accompanied the other Mobians to Knothole.

Having found a home in Knothole, Bernie and Jules resumed their role as Sonic's parents, particularly since Charles' did not have his free will intact and was now under Eggman's control. Bernie was adamant that Sonic eat a full breakfast before leaving their home, and made sure he attended school.

In 3236, Bernie was one of the many Robians that was de-roboticized by the Bem. Although her husband Jules was not, Bernie continued to be the wife and mother she was as if nothing had changed.

After the Xorda
Following the Xorda's attack and Sonic's return from space, Bernie continued to be the mother Sonic lacked for years and made sure Sonic was well fed and attended school. She had to be reminded by Jules however that Sonic had grown up in her absence.
