Hubbard is an Agent with Homeland Security that arrives at the Miami Metro Police Department following an attack by Wormwood. She was previously stated to appear within the hour, due to the development of the biological materials required to create Wormwood on the boat named Ricochet Rabbit, however the attack by Beth Dorsey occurs just before this interview changing to an instant insertion of Homeland Security into the Doomsday Killer Investigation.
Agent Hubbard is the newest Federal Agent to appear in the series, fitting with the current theme that every "even" Season the FBI or some government agency becomes involved in a case. According to Hubbard, she understands the worries of Miami Metro Homicide and states that they are only "temporarily" taking over the Doomsday Killer Investigation to find out all known associations of Steve Dorsey and Beth Dorsey. Regardless, the team feels uneasy with the feds getting involved in this case and dislike cooperating with them.
Agent Hubbard is a woman who appears to be in her late 30s to early 40s with long, blonde hair and bright blue eyes. She has a moderate skin tone and wears professional attire fitting of an agent, basically a feminine styled suit.
Agent Hubbard is a practical agent, she retains her professional personality and the importance of national security in her work. She understands however the discomfort that the police force has with agents and tries to reassure them that their involvement is only temporary. This remains true following their realization that the Dorseys were in fact not "terrorists" and allow control to return to Miami Metro Homicide in the Doomsday Killer Investigation.
Agent Hubbard makes her initial appearance in Season Six.
