Blue

From the moment they were introduced, Blue was described as the "hot doctor" of the crew, being very popular because of their physical appearance and career, as well as the most capable member, even outclassing Purple, who is a more serious and focused Crewmate, and Red, despite Red being the captain and technically having higher authority. Blue came off as charismatic, determined, and poetic, having a doctorate in poetry, and caused almost the entire crew to "swoon" over them by simply speaking inspirationally and looking at another Crewmate, including Purple who is usually the more grounded member of the crew. This is shown in "You Can't Be Hot and Smart" where they make almost every Crewmate in the episode fall in love with them. Blue had a very keen intellect, as they came up with the idea of using Orange's backup trust balls to seal a hole in Storage caused by an asteroid. They also knew their crew very well, as shown when they were able to lure Lime (who is usually paranoid and disconnected from the crew) out of the vents and convince them to scan. Blue cared for their crew's safety, being determined to ensure everyone's safety following White's death.
