3D Scan Mode, also called Lock On, is a feature used by androids and robots. Major Metallitron is seen utilizing it in Dragon Ball, and Android 15, Android 14, and Android 13 are seen utilizing in the movie Dragon Ball Z: Super Android 13!
When Goku goes up to the third floor of the Muscle Tower, Major Metallitron scans over his body to see that Goku is not human, but he is unsure what species of alien Goku actually is. The ability is later used by Cyborg Tao to lock onto Tien Shinhan's biological waves in order for his Super Dodon Ray to not miss when proceeding to fight his former disciple at the 23rd World Martial Arts Tournament.
In Super Android 13!, during their search for Goku throughout a city, Androids 15, 14, and 13 rely heavily on a mode that allows for a three dimensional scan of their surroundings. This feature even allows them to see straight through buildings, leading to their discovery of Goku. It also has some way of measuring power level, as seen when reading Goku's level before proceeding to attack. One final feature is a synchronization with Dr. Gero's Super Computer, which feeds them information and shows scans of weak points during battle. When using this mode, their eyes flash and make repetitive beeping noises. They also see a blue interface, filled with white graphs, numbers, and other various technological markings.
In Dragon Ball Z: The Return of Cooler, the Meta-Coolers possess their own version of 3D Scan Mode, which they can use to locate and Lock-On to their opponents in order unleash the Lock-On Buster technique.
Although he is not an android, Master Roshi utilizes a similar technique in Dragon Ball Z: Bojack Unbound, when he finds some ladies sitting at a table, though it was likely done for comedic relief. Another possibility is that Roshi's sunglasses, which he commonly wears, had been equipped with a 3D Scan Mode designed to locate attractive women, which would be a quite plausible scenario considering Roshi's perversion (nor would it be the first time he used technology to do perverted things, such as when he used the Micro Band to try and spy on Bulma and Launch).
- The 3D Scan Mode was based on the Terminator's HUD scanning modes from the film franchise of the same name.
- Although Android 16 is not officially stated to have used this form of scanning, it is highly likely considering he is a Red Ribbon Android and he can scan power levels.
