(Tyla is born as a Demi-Human with long blonde hair and green eyes she was being called a demon because she's a Demi-Human and Tyla wasn't even a sister to Maria but Shadow knows that she was his best friend on the Space Conley Ark as the scientists looked at her as the scientist looked at Tyla regrets even being born in the first place on the Ark. Dr David held Tyla inside of that capsule for 3 years keeping away and trapping her inside the capsule away from her big sister Maria, her grandfather Professor Gerald Robotnik and her best friend Shadow the Hedgehog in the Space Conley Ark because Tyla was diagnosed as a baby with a illness disease called Nero immune deficiency syndrome as giving so much information about Tyla to the G.U.N so they could destroy all evidence about her illness disease and all her history and they could take her away as well as Dr David has been sending all the information and evidence for Tyla’s illness disease to the G.U.N aka Guardian Unit of Nation HQ to from the Space Conley Ark all the way to Planet Earth).
