Banner is considered one of the greatest scientific minds on Earth, possessing "a mind so brilliant it cannot be measured on any known intelligence test." Norman Osborn estimates that he is the fourth most-intelligent person on Earth. Banner holds expertise in biology, chemistry, engineering, medicine, physiology, and nuclear physics. Using this knowledge, he creates advanced technology dubbed "Bannertech", which is on par with technological development from Tony Stark or Doctor Doom. Some of these technologies include a force field that can protect him from the attacks of Hulk-level entities, and a teleporter.
