Andrew D. Kaboom

"Hey, you can't make an omelet without blowing up a few eggs."

- Andy

Andy is a rude, foul-mouthed and short-tempered bomb built by Tex using parts of a protocol robot and some of her 'personal items' 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, at least when it is not on his own terms, when Tex threatens to detonate him if he will not translate for them. The desire to explode 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 when Caboose wasn't looking, and then a skull so Andy can translate a recording for them. This leads Caboose to believe that Andy has turned into a real boy and then died.

In Episode 54, Caboose tells the rest of Blue Team that Andy knows Sheila from the past, but doesn't give any kind of explanation afterward.

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. This is important since when Andy was first introduced he was too heavy for anyone except for Caboose to carry, but eventually he becomes light enough for others, such as Tex and Sarge to carry with ease.

During the logs of the crash in Reconstruction, Andy can be heard in the background, evidently disappointed with the size of his explosion. This is only shown in the Sponsor's version of Chapter 5. In Chapter 9 of Revelation, Doc mentions a talking, translating ball, but dismisses the idea because there were too many rude people around already.

Andy is known to make all kinds of rude comments, usually ending in a "Zing!". This is first shown when he commented on what Grif looked like when he was drugged.
