When he was a human, nobody warned him about the dangers of the flyswatting making conveyor. Because of that, he tripped and fell into the conveyor and was crushed, melted, and even spun around very fast turning into a bunch of flyswatters he is now. He traps bugs in cells and they woke up here. Always assumes that everyone knows him and is afraid of him, though that's not true at all.Thomas has quite a temper in him. He's very angry and probably gets even more angry if someone asks who he is.
