"Lighting them up!" - Marissa-B063, about to detonate explosives
A member of the Spartan-III Beta company, Marissa, like Kyle-B113, was brought to this universe during the events of Operation: TORPEDO, making the UNSC believe both were killed in the assault. They both helped form Spartan Team Zodiac (Marissa having to coax Kyle into joining up) and were integrated into Hellcat Squadran with the rest of the team.
When not on a mission, Marissa is a somewhat open individual, and is usually the only one who can get Kyle, a fellow member of Beta Company, to speak up.
When on a mission, Marissa chatters a lot, but she is sure to warn her allies of either enemy mines or when she's ready to blow stuff up.
