Hope Pym is the daughter of Hank Pym and Janet Van Dyne, and twin to Henry Pym Jr. (aka Big-Man). Hope became obsessed when the newest team of Avengers appeared, feeling they were disgracing the memory of her father (who died as an Avenger) and mother (who died "of a broken heart"). She used her fortune to arrange for an unknown individual to become Ion Man, sending him to assassinate Cassandra Lang . Hope felt Cassandra was a mockery of her parents and that she, herself, should have been the one to carry on the legacy started by her father when he first appeared as the original Ant-Man. Ion Man failed in his attempt and was temporarily dispersed by Mainframe.
Hope Pym was created by Tom DeFalco and Ron Frenz and first appeared in A-Next issue 7 (1999) as part of the MC2 Universe. As of yet, there is no 616 or 'main Marvel Universe' counterpart of Hope Pym.

Hope arranged for the formation of the Revengers and she and Henry, using their parents' security codes invaded the Avengers Mansion. There, they captured Tony Stark, Clint Barton, Edwin Jarvis and Scott Lang and ambushed the Avengers. She then set about torturing Cassandra Lang, planning to kill the Avengers, convinced she could lead a better team. Her brother, Henry, turned against her and after the two teams fought it was he who stopped her from initiating the Mansion's self-destruct, which would have killed both the Revengers, the Avengers and their allies.
Sometime later, Hope recruited Magneta, the 'mistress of magnetism' to replace her brother, Henry and launched another attack on the Avengers, who were left weakened following the events of Last Hero Standing. After two unsuccessful attempts to destroy the Avengers during Last Planet Standing, both Killerwatt and Sabreclaw defected to the assembled heroes to prevent the planet's destrution. Meanwhile, Hope led the Revengers and other villains (and civilians) in looting the ravaged New York City.
