Ruby "Pufferfish" Peet is an eleven-year-old with the worst allergies in recorded history. She is allergic to everything from pizza to talking about and being peppy. She is the leader of the group and as Ms.Holiday indicates, "stubborn". Before Brand became the director, the old director allowed the team in getting what they want, especially Ruby, and this is seen when the team asked for Jackson to leave the team, but Brand denied their request, nearly more than half of the first book. Even though it may seem that she seems that she is not very powerful in her upgrades, as seen with her fight with Flinch, she is powerful. The reason she is powerful in a fight is that she can detect danger, so she knows where and when one will try to attack her. Also, she can detect your exact weaknesses, so she knows where to strike.
