Oh yes. He's like, the Batman of Marvel, with this constellation of characters spawned off from him in some manner.
Hank, Janet, Ultron, Vision, Scott, Cassie, Eric, Viv Vision, Jonas, Sparky, Bill & Tom Foster, Rita DeMara, Jocasta, Nadia. If there was ever an 'all-hands on deck' call put out to everyone whose powers derive from Pym's work to assemble, they'd be larger than most Avengers lineups! (Although Ultron's invitation might get lost in the mail. He's the black sheep of the family, much more so than O'Grady.)
Plus other characters whose powers derive from his technology, but are further afield, like Atlas/Erik Josten and the various members of the Order.
