Barry sometimes talks to himself and calls himself "Other Barry." Occasionally he refers to himself in the third person. In addition to conversing with himself, he has also been known to speak to, but not with, his gun.

Following his conversion into a cyborg, Barry seems to have developed a more focused obsession on getting revenge on Archer for twice dropping him off rooftops and once stealing his girlfriend, whom Archer later described as "the Pel\xe9 of anal." Barry, though he appears to be a good guy, is considered an annoyance at times. Additionally, he has a darker side. After a fight with his alleged fianc\xe9, Framboise, he told Lana he was planning to blow up her car (most likely with her in it).
