Humans aren't afraid of mutants because we're different. They're afraid of us because we're not.


Theo grew up the son of a railroad worker, and born 5th of eight children. When he was fifteen, a Friends of Humanity offshoot known as the Cleansers discovered that he was a mutant, and stirred panic in the local residents. Theo's own neighbors burned his house to the ground to try to kill him, and failed due to his best friend, Kyle Adams.
After the fire, Theo fled, trying to find other mutants for protection. He ended up being held hostage by a family trying to hold young mutants hostage for ransom. The police were able to rescue the teens and get them medical attention, but before he was released, Theo escaped the hospital, in search once again.
After a very careful search on the internet, Theo deduced that there was a place for mutants somewhere in Westchester, New York. So after hotwiring a car, he made his way to New York, hoping to find a better future than present.

  • Humans aren't afraid of mutants because we're different. It's not the fact that we have powers that strikes fear in their hearts. It's how we are the same that makes us a threat. Because everyone is evil. All it takes is the right button. They know that and we know that. They are afraid because they know if the right button is pressed with us, they won't be able to stop us. And that's their button.
  • (After Kael speculates what Christmas will be like) "Are you kidding? With this place's track record, it'll probably be 90 degrees and we'll get kidnapped by elves."
  • "Too many people are like cotton candy. They seem sweet, but there's really no substance, and too much of them will make you sick."


  • Theo is left-handed.
  • Theo is a homophobe.
  • This kid is crazy about trains.
  • He works for Tony Stark and invents cool stuff!



  • Technopathy: Theodore has power over machines. Whether electronic or mechanical, he can control machines with his thoughts. This is still a very elementary ability in its early stages. He has not nearly tapped the power for what it is worth. To control a device or machine, Theo must be within 40 feet of the subject. He must also have at least a basic understanding of how the technology works in order to utilize it. For example, he can operate a car because he has a general understanding of how cars work, but he would not be able to operate a space shuttle, because he has no idea of how space shuttles work. He is able to dive into networks and bypass simple security settings like passwords, but anything that requires a competency in algorithms he will find himself outmatched by. Alien technology of course, he would be unable to manipulate until he learns how it is operated. If someone were to talk him through operating a vehicle or device that he is unfamiliar with, he would be able to operate it, just as if someone showed him manually. He can maintain his control on a device as long as a person normally would be able to comfortably interact with whatever he is controlling. For instance, he could control a car for as long as he could drive it. He can operate a computer just as easily. If Theo is mentally exhausted, he is completely unable to manipulate any devices. He can only operate one device at a time.
  • Technotelepathy: Theodore is able to instinctively know what a machine is processing. Right now he can only understand one machine at a time, and it must be either within 20 feet of him, or connected to a machine that is within 20 feet. For mechanical devices such as cars, this means that he can understand exactly what function a car is performing even if he cannot hear the engine shifting gears or see the parts moving inside. For electronic devices, such as computers, this means that he knows exactly what functions a computer is computing. He knows what program a computer is trying to open or prioritize, and if he focuses closely, he can give fairly good detail on how the process is coming along. In order to know beyond the general details of what a computer is doing, he needs to be fairly undistracted. If someone is talking to him or he is listening to music, he will not be able to use this ability. For sentient computers, such as androids or cyborgs with technology enhanced brains, he can presently hear the surface thoughts of the synthetic beings, but if there are guards against such things, or the being tries to resist at all, he can be easily blocked.
