Personality[]
Gwen is a quick thinker and an instinctive person. She can handle dangerous situations well despite their often unfavorable conditions. An example of this being when her magical powers were drained and Charmcaster hit her with a bolt of magical energy; she immediately reversed the spell and, though she had no power left, she was able to hold herself. Gwen is at times shown to be very concerned with the well-being of things around her, such as her surroundings, the people around her, and those she cares about. She is very strong (physically and mentally) and well mannered, despite her inflating sarcasm and ego at certain times. Gwen is a very caring, compassionate person, as shown by her acceptance of Kevin's past and recent action, as well as her statements she does not care about Kevin's appearance. She is found of Kevin.
