Eva Destruction is an agent with MI-6.
She is in most of the adventures we have of hers.
When we first meet her, she is a barista in a small shop in the middle of London, handling out pithy comments to the customers and giving them her own nicknames as they prepare to order. Despite the almost-but-not-quite sarcastic way about her, it is important to note that Eva knows her coffee.
Ms. Destruction is an Australian who has relocated to England - when I could not discern but she most definitely is from Down Under as her accent and her attitude shows. She is in the second half of her 20s, unmarried but carrying the scars of a few too many bad relationships. She readily admits she is drawn like a moth to bad boys and then has to deal with the fallout when they prove her right - they are bad. She seems to want to carry her reminders openly considering her series of tattoos.
The first recorded adventure shows how she comes to the attention of MI-6 as a more-than-qualified agent-to-be. It also presents Destruction (what a bad name for a character) as someone who speaks her mind, even when it is better to remain silent. She does not suffer fools at all, even when the dolt is herself. She also shows in that drama that she knows how to take care of herself in a pinch. She swings a mean bat and can hurl with ease anything not tied down.
As the series progresses, she learns the finer points of all the normal spy craft and she gains a good grasp of other, more traditional ways of handling trouble like guns and martial arts. She never loses her natural talents, sass and attitude, though.
If the jerk she has to deal with is being extra jerk-y, she will let him know it. She cannot help herself.
