Marble

Marble is a  technician from the Wasp Kingdom, a bug responsible with both building explosives and safely handling them. Though banned from the field for a number of reasons (mainly a general disregard for the safety of both her and her squadmates, but also including a general disregard for things like "laws intended to prevent war crimes"), she would pass the time with a mix of supervised repairs and hanging out in various semi-legal out-of-kingdom venues. Generally cool-headed and mature, their demeanor can allows them to pass off as a significantly more grounded individual than they really are - they pass as calm, cool, and reliable, despite the fact that they are not generally the sort of person who you would actually want dealing with important work.

During the Wasp King's takeover, she would be mobilized into the field and promptly wind up on the bad end of one of her own bombs, losing an arm and an eye and badly scarring over nearly half of her chitin. As she is, her sense of smell is basically gone, and her sight really isn't much better.
