Gloria Baker is shown during her day job as a driving instructor. In the first shot the outside of the car she is sitting in looks like her M.A.S.K. vehicle, Shark. The next shot it has changed to a beige color. Also, the background in these two shots is a quiet lane with trees in the background, but after she gets out the car is suddenly on a busy city crossing.
When Scott is fishing with Daniel, during one shot when he springs a wooden trap to catch a fish, he is wearing a native American outfit similar to Daniel's, whereas in the shot before and after he is wearing his regular blue clothes. He will not put on the Indian garb until the next scene.
The first time Matt Trakker uses the hang-glider function of his Spectrum Mask, (to float from Thunderhawk to Switchblade) the yellow glowing effects that are supposed to surround him during this activity are missing. When he uses it a second time and third time shortly thereafter the effects do appear.
When the M.A.S.K. computer is selecting the best agents for the mission, it neglects to mention Alex Sector's name.
During the selection of the M.A.S.K. agents, other agents are briefly visible each time before one is selected. At one point, Buddy Hawks is visible but is not selected.
When V.E.N.O.M. and M.A.S.K. come face to face and Matt says "You never will, Mayhem", Buddy Hawks is visible even though he wasn't part of the mission at all.
