Marie is voiced by Eden Riegel in the English version.

When Marie is first met, she seems to be a very cold and antisocial individual. She is sullen, cranky, sarcastic, irritable, very foul-mouthed and often prone to mood swings. She will not hesitate to voice out her opinion or express her thoughts, regardless of how it would make everyone feel. The team is also weirded out when she politely apologizes, commenting that she never seemed like the type who would say sorry.
