13. Peter Parker
Peter Parker, also known as Spider-Man, is one of Marvel’s most iconic characters. Parker has a genius-level intellect that has allowed him to become one of Marvel’s greatest inventors. Due to being bitten by a radioactive spider, he was able to obtain powers that essentially granted him the abilities of a spider. Yet it did not give him everything. Spider-Man’s suits and web-shooters are almost entirely made by Parker himself. The “Spider-Tracers,” stealth suits, and even specialized gear for his rogues gallery have been key inventions. Parker was able to isolate a unique and powerful energy source, known as “Parker Particles,” so powerful that he ultimately abandoned the research to prevent it from falling into the wrong hands.
