- Shadaisy Robotnik

Maisy Shadaisy "Egggirl" Robotnik is the Diabolical daughter of Dr. Eggman who never heard  anything of Eggman Nega. She even has a crush on her Intern Cousin Snively, but he always declines the Relationship and rather date the Iron Queen over her. She's not only Princess of the Eggman Empire but also Queen of the Shadow Androids. Though she does only loath Shadow and Sonic for her father's failure of domination, but Metal Sonic for betraying her father in Sonic Heroes. In Angela O'Haru and the Royal Suspension she framed Princess Daisy for the attempted murder of King Richard of Sarasaland. and Daisy got the blame for it. After being thwarted by Team Dark, Team Chaotix, Wreck-It Ralph and Pauline, she was banished from Mobius by the Council of Acorn and sent to the Mushroom State.

Origins
When Maria Robotnik was killed, Henry Robotnik collected his Niece's blood and DNA as a boy, years later, he was at his desk, thinking that his son, Ivo (Alias Dr. Eggman), can help him clone Maria as the only way to bring her back, but when he died, he inherited the Tube of Maria's DNA and Blood to Ivo, and before the events of Sonic Heroes, Dr. Eggman accidentally added Maria's Blood in the first Shadow Android Capsule. And the only human Shadow Android (after Neo Metal Sonic was defeated) was born. Then Eggman realized that she's not wearing clother after she hopped out of the tube, so he made a replica of Eggman's clothes, only blue instead of red, and gives it to the girl then he named her "Shadaisy" (which happens to be his mother's Maiden name).
