Tecna is highly intelligent. Like any good nerd, Tecna thoroughly enjoys math and science. She spends a lot of time doing things on her computer. As intelligent as she is, though, she does not always understand non-technical things, like manual labor. Some of the simplest things, like brooms and buckets, are completely foreign to Tecna.
Tecna is not very good at expressing emotion. She looks for logic behind everything, and is not good at understanding emotional-based decisions. She also does not outwardly show a lot of concern for her friends, though deep down, she truly cares for them all, and would do anything to help.
Tecna has an irritatingly forced crush on Timmy.
