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."[66] He holds expertise in biology, chemistry, engineering, physiology, and nuclear physics. Using this knowledge, Banner 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.
