[Non canon]

Gismo has been accused of (allegedly) raping Cyberlife Bus 8. Cyberlife Bus 8 defended the dog, saying it was all part of God's plan.

Info
Gismo likes raping other female dogs while out for walks.

When RoTech Bus was asleep he chewed out all of his tires and RoTech Bus couldn't move. He told Gismo to give him the phone to call a tow truck but Gismo chewed the phone instead. RoTech ended up staying inside his house for a whole week until Todd Car visited and called a tow truck.

All of RoTech Bus' family and friends call Gismo a demon dog due to his erratic behavior during family reunions.

Gismo helped defeat the main villain in Cyberlife Car IV.
