Mech is not the only thing Theo has ever worked on ever since he had become interested in robotics. At earlier age, he managed to build three advanced robots, each one with different AI (thus, different personality) and with different purposes around the house and his lab.
Number 1- Nevile-first of the robots, brain of the team. Using the full capacity of his AI and processors, Nevile can perform multiple calculations at once and come up with as many outcomes regarding experiments as possible, and is the one that helps Theo and Fey around the lab, often coming up with useful ideas. Despite being serious most of the time and overly sarcastic, he shows great respect towards his creator and Fey, and often shows concern for his two younger partners, Jenissa and Bruce (although he manages to hide all the worrying and concern deep under his sarcasm and poking at them.)
Number 2-Jenissa-While rarely working around the lab, Jenissa serves as some sort of maid in the house and assists Theo's mother with the house chores. Always happy-go-lucky, playful and loves to sing or just hum while working. Despite being somewhat ditzy and airheaded, she always manages to perform her duties with utmost perfection. Adores Bruce and always spends her free time around him. Excellent babysitter (ask Theo's little cousins XD)
Number 3-Bruce-Biggest and strongest of the three robots, Bruce is the muscle of the team and helps with the heavy duty work at the lab or assists Theo's father in his car mechanic shop (some customers come just to see the 7 foot tall mechanoid lifting cars with ease), or serves as the guard of the house and lab. His extremely tough build and systems allow him to pick up objects that can weight even for hundreds of tons, and thicker armor allows him to withstand heavy firepower. When not on duty or arguing with Nevile, he spends his free time with Jenissa, acting as her guard most of the time. Loves to call Fey and Ms. Cameroon "lil' ladies", his own way of respect towards them.
