History
Origin
Pym Technologies was the scientific research and development firm founded by Dr. Hank Pym. After years of working together, Pym's disenchanted former protégé Dr. Darren Cross ousted Pym from his own company with a narrow margin of one vote by the board of directors. With Pym out of his way he proceeded to embark on a lengthy research project to recreate Pym's discoveries with Pym Particles.
Cross Technologies Enterprises
Within a few short years Cross had managed to build a functional method of using Pym Particles to shrink inorganic matter to tiny sizes and created the weaponized Yellowjacket's Suit designed specifically for combat and espionage. However, the means to shrink organic matter continued to elude him. Ongoing frustration and continued exposure to Pym Particles also had a detrimental effect on his sanity, and when estranged Pym's daughter Hope, who likewise worked at the company, saw this and how close Cross was to perfecting the technology, she grew alarmed and turned to her father for help. However, Cross continued his plans to sell the Yellowjacket technology and rebrand Pym Technologies as Cross Technologies Enterprises, even contacting Hydra.
Along with Hope, Pym organized an infiltration plan to prevent Cross's sale of the Pym Particles. They recruited Scott Lang and were ultimately successful in destroying Pym Technologies and stopping Cross's plans.[1]
