Opacity is very intelligent. He keeps to himself and is quiet around a group because he is analysing and computing within his mind. He is very curious, and overly bold and tends to "touch the stove to know it's hot" rather than follow the warning label. He is very much a judgemental soul, and is very particular in who he places himself around. However, he isn't obvious in who he likes or dislikes, as he keeps to himself to avoid confrontation all together. He is easily angered, and tends to hold grudges for longer than necessary. He also is a firm teacher and has little patience for stupidity (or just simply slower learners), so therefore his tolerance of children is next to none. Opacity isn't a fan of women, especially women of the Jungle because of his experience with Quark (his mother's lover who essentially triggered his father's suicide). He also struggles with understanding the emotion of love, and is easily frustrated when around couples. When he becomes frustrated he becomes eerily quiet and will do his ultimate best to exit the situation, as it brings back memories from his rough childhood.
