Characters
Red vs Blue
Private Michael J. Caboose
In the early episodes of Red vs Blue, Caboose was not originally intended to be "the stupid one". According to DVD commentary, he was originally supposed to be designed with only a hint of smarminess or chauvanisticness. As time went on, many fans would comment on how they loved Caboose's "stupid" antics, Joel Heyman began toying with the voice, which became slower and began to put emphasis more and more in unusual places. Caboose's IQ began to decline, at first being simply regarded as unintelligent, he eventually became childish with the IQ and behavior of a 6 year old. Lately his intelligence has dropped even further, to the point where he appears to be almost completely oblivious to the world around him and lacking any sense of reason or common sense, following broken logic instead. Fans have attributed his severe decline of intelligence to O'Malley's time spent inside Caboose, possibly leaving him with brain damage. It was also stated in the Season One DVD Commentary that his decline in intelligence was at least partially attributed to the bombing and consequent deactivation of Sheila.
O'Malley while possessing Caboose
While possessing Caboose, O'Malley had surprisingly limited amount of control (considering how well he was able to handle Doc), he would appear (mostly to Tucker) for only a few seconds every so often to deliver a threatening line to whomever was close by (such as, "Don't. Ever. Be. Alone."), giving him a demented personality. When O'Malley became present, Caboose's voice would drop very low. In Episode 40, after O'Malley has made the jump to Doc, Caboose is somehow able to summon incredible anger that parallels how O'Malley acted, albeit with his own inner thoughts such as certain objects that make him angry, like Red Bull and "kittens covered in spikes". In this same moment, Caboose's voice dropped in the same way it did with O'Malley. As of the fourth season, Caboose has yet to summon any outburst quite like this.
The Strangerhood
Wade
Wade appears to be a stereotypical party dude/hippie, and appears to be permanently stoned. He often recalls events that never occurred, and speaks slowly, often calling people "Dude", or "Man".
