Powers and Abilities
According to Tadashi, Baymax was programmed with considerably impressive strength (he is stated to be able to lift 1,000 pounds) and the ability to store a massive amount of data, making him highly intelligent in several fields, should he take the time to access the information. He is also programmed with 10,000 different medical procedures and equipment, such as defibrillators equipped in his hands and an antibacterial spray that is dispensed from his fingers. His body is also equipped with a heating system that warms anyone lying on him.
However, his vinyl building made him rather vulnerable in harsh situations, resulting in Hiro creating a special, battle suit to utilize the healthcare robot in defeating sinister villains about the city of San Fransokyo. The first suit was equipped with Ninja-esque skills downloaded from one of Hiro's tai-chi videos, enabling Baymax with karate action.
Baymax's true powers, however, lied within his "2.0" version. The massive, red battle suit that gave Baymax incredible strength, flight via a set of rocket thrusters and back-mounted wings, and a scanning system within his helmet; giving him the ability to track and find anyone using only their medical information, such as body temperature and heart rate. Baymax was also given rocket-fists that, when unleashed, can cause an incredible amount of damage. The back of Baymax's armor was also equipped with magnetic extensions, allowing Hiro to safely ride atop the robot's back (when wearing his own armor) without the fear of falling.
