Ok so, I'm a geek... Sheila is named after the tank in
redvsblue . Call it irony.... Sheila is about 2.4 pounds at 4 1/2 months but she thinks she's huge
Here is a short description of who (what?) she is named after.
Sheila, originally named Phyllis, is the AI of the Blue army's M808B Main Battle Tank. She seems friendly enough, but, being a tank, she's got a habit of blowing people up (including her own teammate Church, thanks to the poor piloting skills of Caboose and the indiscriminate nature of her auto-targeting system). Sheila gets bombed to death by Sarge's dropship early on, but is repaired by Tex a few episodes later. She seems to despise Tucker, and calls him a retard over and over when he tries to drive her. She also seems to like Caboose at least a little (she's the only person in the canyon who does), however, she ends up falling in love with the robot Lopez, and the two of them elope. She appears to understand Spanish, and thus is the only "person" in the canyon who can comprehend Lopez. At one point, she and Lopez attempt to lead a robot revolution against the humans in response to the perceived abuse suffered by the Gulch's robots: being constantly blown up or possessed by ghosts (even though the others also suffer same), but after Lopez is kidnapped by O'Malley, she puts her differences aside to help retrieve him.
