Andrew D. Kaboom

Andy is a bomb built by Tex using parts of a protocol robot with the purpose to kill O´Malley. Andy frequently expresses a desire to destroy things by detonating himself, much to the worry of the Blue Team, who attempts to calm him down through a "therapy session". However, Andy later wishes to avoid detonation when Tex threatens to detonate him if he will not translate for them. This desire resurfaces later when Andy attempts to convince Church to let him guard, and in the process, destroy the Blue Base. Caboose reveals that Andy had told him about the Reds' secret meeting, but the rest of the Blues refuse to believe Caboose at first, as Andy remains silent when they approach. However, he has an outburst when Gary insults him and reveals that the two "are not on speaking terms".

Because Tex built Andy from the remains of an old protocol droid found on the perimeter of the base, he is able to understand the Alien ("Crunchbite"). As a result, he joins the sacred quest group to act as a translator. After the failure of the quest, Caboose brings him back to Blood Gulch. In episode 76, the Reds replace Andy with first Lopez's head, and then a skull so he can translate a recording for them. This leads Caboose to believe that Andy has turned into a boy and then died.

Andy is very self-conscious about his weight. In episode 76, after O'Malley repeatedly calls him "bowling ball", Andy asks Caboose if he is that fat, claiming that he has been working out. When Sarge steals Andy, he remarks that Andy is much lighter than the last time he tried to pick him up and Andy is relieved that someone has noticed.
