Maria Robotnik

Maria was described as beautiful, yet frail in appearance. She was a young human girl who stood about a head taller than Shadow. She had wavy shoulder-length blonde hair, light blue eyes, and pale peach skin. For attire, she wore a dark blue puffy-sleeved blouse with a white stripe running down the middle over a light blue, knee-length dress with long sleeves, a dark blue hairband, and matching blue shoes with white soles.

She was born on Earth, and when she was young she traveled to Spagonia with her family. Sometime after, Maria contracted the incurable and fatal disease Neuro-Immune Deficiency Syndrome (NIDS). As a result of this, her grandfather Gerald Robotnik brought her aboard the ARK in order to try and develop a cure for her illness. Due to her illness, which left her frail and weak, Maria needed constant attention, which meant she could not leave the ARK's hospital, leaving her confined in space. Additionally, her condition was only mitigated by the low gravity onboard the ARK, further confining her to the station. Despite getting medical help, Maria only grew weaker over time. While looking down at the earth from the ARK, Maria developed an interest in it and longed to return home.

Onboard the ARK, Maria was looked after and cared for by her grandfather. Maria came to mean everything to Gerald, and the two of them would work and live together onboard the ARK. Maria also befriended a young boy named Abe whom she would play with.

Eventually, Maria and Shadow got to the ARK's escape pods in the research center. There, Maria saved Shadow by initiating his escape pod's launch with him in it. However, the G.U.N. soldiers were right behind them, and Maria ended up being mortally wounded by a G.U.N. Soldier's gunshot. With her last strength, before saying goodbye, Maria asked Shadow to protect the world for her sake and give everyone a chance to be happy, just as the black hedgehog was jettisoned from the ARK. Afterwards, as Maria perished, her last words were "Bring hope to humanity."

While frail in appearance, Maria was strong in spirit. Eternally cheerful, optimistic and positive despite her condition, Maria could see the good in almost anyone or anything. She was likewise a very kind, loving and generous soul who always put others before herself, supported her friends, and held an unconditional love for the people of the world, even showing compassion towards her enemies when they were distressed. Because she never got to visit Earth after she was moved to the Space Colony ARK, Maria was very interested in the planet and wished to see it. She was as well very encouraging as she could make others accept themselves and calm others down when in stressful situations, including Shadow.
