So I have a pony OC for a story, whose special talent relates to diseases, viruses, and other toxic materials, and I've settled on two potential names for her - Quarantine (Simple and direct but makes her come across perhaps too villainously) or Merry Typhoon. (Takeoff on Typhoid Mary, more in line with what a sane parent would name their child, but seems like it's stretching things a bit.)

Which do you think I should choose? Or do you have other suggestions?
