Lien-DOS is a holographic program that takes the form of an echidna. She was created by Dimitri as an assistant after Lien-Da betrayed him. She developed a personality of her own and a desire to explore the world. She lives with Dimitri in Haven, helping him repair it.


Lien-DOS is loyal and helpful, trying to do whatever she can to help her allies. She was programmed to be very polite, and will call new acquaintances "Mr." and "Ms." She is also excitable and sees everything with a sense of wonder, especially since she is new to the world. She wants to befriend everyone. She is sometimes naive and has an innocence about her. There are many concepts she doesn't understand and has a tendency to take things literally. Despite all this, she is still a computer and will on occasions ramble off a bunch of statistics. She is actively learning and thus her speech is a mix of strict computer-like speech and of casual speech she has picked up from others.

Physical Characteristics


Despite being artificial and made up of nanites, Lien-DOS is pretty realistic looking. She takes the form of a light red female echidna. She has light blue almost lavender eyes. Unlike other echidnas however, her dreadlocks start on the top of her head rather than the side.


Lien-DOS's form wears a simple yet sophisticated dark purple sleeveless dress. She never wears shoes.


Lien-DOS stands very calm and gentle, with a kind look on her face. She usually has her hands folded politely in front of her or behind her back. She stands very straight and proper, but sometimes when she gets excited she'll start jumping up and down.


Although she is a hologram, Lien-DOS is solid and able to manipulate objects since she is made up of nanites. This is similar to the way NICOLE is (or the Doctor on Star Trek). Also, she is able to use her nanites to create shields and the like. However, while NICOLE has a whole city of nanites, Lien-DOS only has those that make up herself, so she must use part of her form to make the shields. Her nanites are tightly compacted however, so she has many of them. She is able to disperse her nanites into a cloud to avoid hits.

Her base transmitter is with Dimitri but she is able to use other transmitters as bridges to boost her signal so she can be in most places. But she can't be anywhere with no technology nearby or where it is blocked.

She is able to interface with most computers and even control certain technology.

She is also able to fly through the air at high speeds.

She has advanced scanners, especially tailored to health diagnostics.

Being a computer she can perform advanced math calculations in an instant.



After Lien-Da betrayed him and he was rescued by Sonic and Tails, Dimitri decided to program an AI to assist him. He did it during his time at the Science Center in New Mobotropolis. He named her "Lien-DOS" after Lien-Da. Lien-DOS was especially designed to prevent the "box incident" from ever happening again. Dimitri began planning her while he was still trapped in the box. He then spent most of his time at the New Mobotropolis science center programming and designing her. NICOLE loaned some of her nanite technology to the project.


When Lien-DOS was first created she lived exclusively at the science center helping Dimitri. However, she was curious about everything and strongly desired to go out and see the world, so Dimitri set up her ability to use other technology as bridges so her signal would be strong enough that she could leave the center. She has gone out on her own as well as with Dimitri and Luger, meeting new people and having new adventures. These included going to her first Christmas party, a night club, and going to the Chaos Hotel with Dimitri. She also helped Roy retrieve the life emerald after it had been stolen, and was also involved in the search of the eighth chaos emerald. Later, she went with the others to Planet Q to stop the invasion. She was one of the people trying to solve the mystery of several super powered meteors that crashed to the planet one night, as well as the robots that will stop at nothing to get them. She helped Blizzard prepare a Christmas party in Glacier Plains.


Feel free to add your characters
