With the formation of Night Rangers, in return for being rescued from the Zeus Protectorate by Shane Wright (Mind Storm) and the others, Alicia wanted to prove her worth by bolstering the team with artificial members. As she had an Alpha ability that enabled her to design and build almost anything she could think off she set to work. Having a strong interest in ancient history she decided to create her first robot to have the resemblance of roman centurion. Giving it intelligence though was not as straightforward until she "invented" a brain pattern recorder. Then with the permission of the male team members she installed her robot with the combined brain patterns. Within hours it became sentient due to its self-learning capabilities. Believing that forcing it to obey commands would result in little more than a drone as opposed to a valuable individual asset to the team, Alicia left out any normal restrictions but did place a manual override to be used if Centurion became hostile.

The override though was not needed for once sentient Centurion was happy to serve its creator by helping her achieve her goals and since Alicia’s goals were the same as the Night Rangers he elected to help the group in general. In time she took a big risk and removed the override altogether for as long as the programming existed there was a chance one of the team enemies would be able to use it to disable Centurion. With this gone he now was an individual with control over his own destiny but despite this he continued to willingly serve the Night Rangers, all the while building a “personality” based on experiences.

Sometime after several months had passed a chance encounter with CLARA inspired Alicia to build Centurion a "sister". By this time he had fully developed his own personality and was making choices for himself without waiting for permission from his creator. He had also learned how human beings treated those different from their own race and was growing concerned that the Night Rangers might eventually reject him and he would be left alone. The chance to have a companion therefore appealed to Centurion and he asked to assist in the project. Alicia honoured the request as she believed it would further add to Centurion's "personal" development.

Having built the skeleton, Alicia discovered her new robot was too small to carry a large capacity battery. This had not been an issue with Centurion since his systems were less advanced and drew less power. With the project nearing completion it was too late for a redesign, so Alicia decided to have a rethink. The female robot would obviously need frequent recharging and that would be a major practical problem because her creation could not exactly tow around a generator, nor plug itself into a power socket in the middle of a battle.

In thinking about what motivated her to design her first creation as a roman warrior, Alicia had an idea in solving the power problem by sticking with the ancient soldier theme. She decided her new robot could perhaps be a “knight” and therefore if she built a horse then it would have the space to carry a mobile generator. The female robot therefore became “Tech Knight” and the robotic steed built for her, Alicia called “Mercury”. To make full use of the quadraped platform Alicia decided to include a full sensor suit and gave it offensive capabilties in the form of a heat blast and a means to electrifiy its outer shell.

As Centurion has been brought to life via the brain patterns of the male members of the Night Rangers, Tech Knight was brought to life using the brain patterns of the female members of the group. Mercury was given a less advanced individuality, more geared towards being subservient to its rider since Alicia intended it to work as a team with Tech Knight. Despite this it was given some autonomy in order to protect itself and its rider from danger. Being of a more advanced design than Centurion, Tech Knight achieved sentience in less than an hour.

Just as with her “brother” she was keen to serve her creator and became an active member of the Night Rangers. However Tech Knight's "personality" presented itself in less than a couple of months and she even developed her first “emotions” quicker than Centurion. As Tech Knight continued to expand her mind she felt the desire to learn and that mean she developed a taste for adventure. Consequently the time spent waiting around between missions was irritating for her.

In time Tech Knight concluded that she had out grown her ability to function within the Night Rangers limited “mission parameters” of fighting anti Alpha criminals and concluded the wasted down time would better served another way. Having developed an understanding of what was right and wrong, Tech Knight decided that her time would be better spent fighting crime on a broader scale. She therefore approached Alicia and requested she be granted leave from the Night Rangers and take her own path. Though to many people she would just be regarded as a machine, Tech Knight had the capacity to care about her “friends” and was concerned if she left the team would suffer by being down a member. Consequently she would not leave unless it was alright with everyone else, so Alicia agreed to talk things through with Wright.

He was none too pleased with the idea but could not fault Alicia's logic which essentially boiled down to the fact that if the Night Rangers were fighting to prevent the rights of Alpha's being abused then they had no right to choose to subjugate Tech Knight. The outcome of the discussions was Tech Knight was allowed to leave, without any stipulations. It was then that the team was struck with another bombshell for, Centurion decided that Tech Knight should not be left to fight her battles alone. Since he was older he had more experience in the outside world than Tech Knight and already aware that humans could be hostile towards something they did not understand he felt obliged to protect his “sister”. Though Shane did not want to lose another member of the team, he granted the request, for having allowed Tech Knight to leave could not be seen to change the rules in regards to different “people”.

Now on their own they were able to choose their own goals and use their unique abilities to hand out justice. From time to time they have returned and reunited with Alicia but have never reintegrated with the team full time. As well as this they have also allied themselves to other hero groups both as individuals and as a airing but normally they prefer to fight crime on their own terms.

Experience over time led to Tech Knight wearing clothes. Though they serve no purpose to her, she discovered that when rescuing civilians they would usually be in a state of panic and since her metal form provided nothing to grab hold off, she decided to wear clothing. This certainly helps when people are trying to hand on to her whilst she gets them safety with Mercury.

Though CLEA does not regard the pairing as a special asset they are recognised for their heroic deeds, hence their inclusion on the database.
