Bonnie

Bonnie (ボニー, Bonī) is the Derringer 's automated computer, specifically a new 8000 model, as remarked by Matt. When Matt is playing darts, he yells at Bonnie to lower the temperature as it is too humid in his room. Later, when Matt and Hiroshi are inspecting the second bomb, Hiroshi almost touches it, but Matt stops him and shows him that Bonnie has detected an invisible barrier around it. While disarming the bomb, Bonnie had already analyzed its composition and later moved a camera to allow Hiroshi and Matt to see the leaking pipes in the block with the bomb.
